I was just interested to see if you were using toothpaste cuz you had toothpaste sitting on your counter last time and if so maybe the active ingredient of peppermint is what's giving you the ability to make this work.
I'm glad you were showing this video without any secrecy. You say water is the most thermally conductive of liquids but what about gasoline... gasoline is kind of like peppermint oil maybe it's not the purpose to find something that's naturally cooler maybe these liquids don't conduct thermally as well... Either way super fun video thanks 💯
I was fortunate enough to have someone of similar ability to clearly explain for chemistry one year. He was considered a bit of a "hottie" by the girls too, so that kept them quietly shy so we could learn, which no doubt helped.
Hi, compounding pharmacist here! Tips for those using the mortar and pestle: start off with small quantities of stuff you need to pulverize or mix, then start adding in larger and larger quantities stepwise to avoid clumps and ensure uniformity! Adding all at once will especially make the fine powder just puff up on you and you'll have a cloud of material on your work surface!
Im a german pharmacy student and alot of the stuff he is doing, really reminds me of compounding lab back at uni, pretty interesting how that pharmaceutical knowledge can be applied in a totally different field
@@herrpez No. You could do the two largest sizes by hand, with enough time and patience. But the surface tension of the oil is too high relative to the particle size on the nano particles, so you'll get clumps that don't suspend properly (think hot chocolate powder at the bottom of a cup). You *might* be able to thermally excite the nano particles enough to break that up. In the same way the sonicator imparts thermal energy, imparting thermal energy causes vibrations that disrupt the surface tensions. But that sounds like a good way to make a big mess. Just going with the two largest size particles is likely to get you about 60% of the way from the cheap to the expensive product in performance, which is likely enough for most applications.
There's no other channel on YT that goes so effortlessly from smoke bombs to banana liquor to thermal paste. It's like finding a channel that has been created through AI just for me. Keep it up!
This reminds me of a lecture on densification. The professor starts by adding golf balls to a bucket and asks the students. Is the bucket full? Some of the students say yes some say no. The prof then adds small bearing balls and ask the question again. The student mostly agree the bucket is full. The prof then adds fine sand and asks again, is the bucket full? Yes the students say. The prof then pours a pint of beer into the bucket. He asks what does this demonstrate. The students postulate and hypothesize. The prof says he is impressed with their answers and then exclaims what this proves conclusively is. There is always room for beer!
This was demonstrated to us by a pastor in church about 10 years ago. Instead of beer, he added water as the last part but I don't remember anymore what he said about it.
@@Dark_eVader Same, except lemons and grains of rice. The rice was supposed to be our unimportant interests and daily life, and the lemons were big Christianity. Lemons first the rice fits, rice first the lemons don't. Only reason I remember because the pastor fucking embarrassed me when he asked my hobbies. I'd rather him sing more gospel for a hour than call me out publicly ...
This guy just matched Noctua (one of the best thermal paste on market) in his FIRST attempt!!! Der8auer is sweating right now Lol. I hope you continue to improve and make it better and beat Noctua by a huge margin :)
I agree with the people suggesting sending some samples to the channel "Gamers nexus". They run comprehensive and thorough tests which I think meshes well with your type of videos. They also aren't afraid to tear you a new one so be aware they'll be brutally honest with whatever result they may reach, good or bad. Though I have confidence in the thermal compound you've made here.
tech ingredients testing is far more methodical than anything GN can come up with. tech ingredients guy is literally a scientist and is more experienced giant in comparison to GN
@@lordjaashin Probably, but the relevant comparison here is between GN and LTT, since not only independent review is needed to gain more credibility but these other guys might be more knowledgeable in software test suites and can potentially test in a wider range of scenarios. Also tech ingredients seem to want the additional reach that these guys can provide.
@@lordjaashin GN is arguably the best independent outlet doing testing specifically for PC hardware. They have the flatness measuring equipment, pressure testing, dummy CPU heat load to control for CPU power variability, and they're working on getting a thermal chamber to control for ambient temps, which is on par with, if not more thorough than the testing in the previous video. LTT will just slap it on a CPU, maybe.....MAYBE turn of dynamic boosting in BIOS and record temps while running some benchmarks. They both have their place on the platform, but GN has a much more scientifically methodology than any other PC tech tuber out there, hands down.
This is the most honest and best explained request for subscribing I've ever seen. I'm in. As an engineer, I really admire your work. I wonder how large is the team behind the videos, they are really well prepared and amazingly well explained. You must have some bloopers, it can't be that much perfect all the time :D
The amount of education you pack in each video is incredible. I feel like I'm at University taking a top level lecture and the best part, is free. Thanks so much for the amout of effort you put in your videos, I really like the videos you make.
This is one of the highest quality channels that I've run across. Tech Ingredients and Applied Science's channel are the two top tier science channels on RUclips. Great stuff! By way of a request, could you do a video on making expanding polyurethane foam, which, coincidentally is the opposite of this one on thermally conductive paste? I've had no luck at finding info on it and would love to see how it could be DIY-ed since it so expensive commercially.
My friend has a spray foam insulation business and I worked with him for a number of years as well as partnered with him for a time. It's not too complicated as there are only 2 parts; isocyanate (iso) and a resin. I'm not certain how easy it is to acquire those for ordinary people but it's probably not. They are pretty toxic by themselves (not immediately life threatening unless ingested but not something you want to be exposed to regularly) and when combined they off gas fairly toxic fumes as part of the chemical reaction and foam making process (off gas = "air" bubbles = foam). Once the reaction is done it's safe though, it's just polyurethane plastic. The resin compounds vary a bit by manufacturer and to buy them require licensing and are sold with each brand's iso even though it's more or less the same (the point being getting iso by itself from these companies isn't very easy). Even if it turns out to be relatively easy to obtain and produce your own resin blend and iso, using it to insulate something won't be so easy. The parts are only liquid when separated and once combined quickly start turning into plastic foam. The reaction only speeds up with heat and mixing which you'll want to incorporate because incomplete reactions are bad (toxic chemicals remember). A large portion of the expense for commercial spray foam is the equipment to apply it and the experience of the insulator. The equipment is purpose built and expensive. Where anyone can install batt insulation with a knife, staple gun/ hammer tacker and a ladder, a spray foam rig is many MANY thousands of dollars. You need a plural component propportioner (google that if you're interested), related pumps, hoses and "gun," heavy duty air compressor, sufficient generator to run everything (~40KW), a method to transport all this equipment, and relevant safety equipment (toxic chemicals remember). Not knowing what you are doing can lead to too many problems to list. None of them are anything you'd likely be willing to live with because you DIYed it. If you have a small area to do, a products like Froth-pak exist but seem unavailable right now. These aren't cheap either and if you need more than 1 or 2 it'd probably be cheaper to have professionally done anyway. To try and replicate these for a DIY method of application is also likely far more costly than it's worth. Unfortunately, not everything can/ should be DIYed. But I would be more than interested if Tech Ingredients proved me wrong in this case.
I believe some of of the precursors for the synthesis of the components of expanding foam are toxic (cyanide derivatives) and are tightly regulated. It would be difficult to do the subject justice without an industrial account / licence with one of the few manufacturers. Synthesising the ingredients for making your own precursor and doing it long way to prove it is possible albeit difficult and uneconomical is more Nile Red than Tech Ingredients.
I'll say it again, this man possesses the ability to articulate exceeding that of my professors or the chief chemists with which I have associated. It is a thrill to listen as sometimes complex subjects are explained simply.
Most teachers regurgitate the book like they are reading to a child. They don't express it in their own words because they either don't truly know it, or because they expect students to not read the book and not want a parent figure in the classroom. I hated school for this very reason - it is a waste of time if you read the material unless you have an actual teacher and not someone just wanting a job.
I just want to say that I truly appreciate the amount of respect you show to the viewer. Both in respecting their intelligence, and their wallet. It's one of the things I appreciate most about this channel, and the cool things you make.
What I love about this video is that it is not just mix this ingredient with that. You will also get an in depth explanation of why certain ingredients are chosen. Thank you
Love it! Going to echo what so many have said about Gamer's Nexus. They have extremely stringent test methodology. They have a dummy CPU heater to control for normal CPU power loads. They do flatness testing as well, so they'll be able to use it on the flattest IHS and heatsink cold plate they have. (they're also working on getting a thermal chamber for controlled testing, too.) :)
I would love to see GN test "both" compounds vs the usual assortment, and the new lab that's in the works will allow them to control the environment far better than the current segmented office building rental. At the bare minimum, Tech Ingredient's explanation of thermal pastes is vastly better than anyone else's aside from maybe Buildzoids explanation of the maths of thermal resistance under the IHS vs direct die for LN2 overclocking.
I’ve always loved your videos. You’ve genuinely helped me think, scientifically, about everything around me. I’m listening to this video on my own DML speakers that have phenomenal performance for pennies. And the best part about them is that I know exactly how they were made and how they can be improved upon. Please don’t let anyone or anything stop you. You are helping my children learn how to think and process and create the world around them for the better.
Excellent work my friend. I, for one, really appreciate the secondary details when you go over this stuff. For instance, you didn't just say "get a paste mixer and toss it in", you described how the machine works. That sort of detail opens if a lot of ideas when I watch your stuff, so it is really appreciated.
I love how you keep no secrets from your viewers, show all the steps, and give us authentic expectations by telling us what we need access to before getting started on each exciting project
Another great video. It's interesting what you said about the zinc oxide (neat vs silane treated) having lower viscosity when mixed with the silicone oil. I think you said that the silane coating on the zinc oxide was supposed to make it more hydrophilic. My understanding is that most (all?) metal oxide surfaces are already hydrophilic because they form hydroxyl groups on their surface (the surface hydroxyl groups are what the silane compounds bond with). In my experience, silane treatments on metal oxide particles are typically to make the normally hydrophilic metal oxides more hydrophobic (by including a hydrophobic group in the silane molecule) for better dispersion in organic solvents. So if your silane coating was actually hydrophobic it might explain the improved dispersion of the zinc oxide in the oil and the lowered viscosity. If the silane is hydrophilic it would be interesting to try and figure out why the viscosity is going down because that seems very counterintuitive so the explanation should be surprising.
The scientific accuracy over all your videos is quite impressive and enjoyable. Only few take the time and pay such attention to detail in order to achieve this level. Thank you for this amazing high quality content, please keep up the good work. Now I just need to come up with a reason why I should order a few kilos of your thermal paste to support you ;)
Спасибо большое, что делитесь информацией и даже помогаете советами, хотя, по сути, это продукт ваших трудов, интеллектуальных терзаний и огромного количества потраченного времени. Я поражён вашим умением объяснять технически сложные термины даже для такого человека как я, я не очень хорошо знаю английский и изучал язык по сериалам и кино. В общем, удивительно, что вы распространяете полученные знания, за это вам моё уважение!
Thank you for the most informative videos! I have 2 comments that might help. 1) I made a pourable KNO3/Sorbitol propellant by using about 30% powdered and 70% 200 mesh KNO3, heated with Sorbitol at a 65/35 O to F ratio. Initially it is as thick as stiff mashed potatoes. I then add 0.2% surfactant ( Polystep B1) and the mixture thins out enough to easily pour! It is like magic! 2) Using multimodal powders, surfactants and mixing under vacuum can greatly reduce the viscosity of a high solids mixture. I make pourable mixtures of powders and polyurethane with up to 88% solids using trimodal powder mixtures, mixed in steps. I mix using a Red Devil 1 gallon paint mixer and a stainless steel beaker with a lexan lid which I attach to a vacuum pump. I only use 1 mix container so there is no loss between process steps. Note, this probably won't work in batches too small on the Red Devi.
Another vote to send this to Gamers Nexus. They do thorough, scientific testing with lab equipment. I love LTT, but it seemed like they really flew by the seat of their pants for their video on your thermal epoxy.
That was part of the point of the video though. Alex was just going ham doing that most pc enthusiasts. I do agree that it's needs more extensive testing.
I concur Gamers Nexus is far better at testing things than LTT. If you wanna be able to put numbers up there that PC builders will under and know they are the way.
It would be interesting to see your thorough treatise of ptfe greases, and their properties. I recently encountered a use case where they were involved, and unintentionally opened a pandora's box. There are various compounds commercially available, all resembling what we would call a ptfe grease, but their properties, and quality vary from one end of the spectrum to the other. High-end (and very expensive) products like Krytox, Christo-Lube, and Tribolube are a world apart from bicycle shop products, even though its not immediately obvious why this would be so. Even the expensive ones vary considerably. They are typically used as oxygen/nitrox safe lubricants for gas cylinder threads and O-rings, amongst others. I'll bet any money you have at least one of them in your lab/shop over there :-). For what its worth, Tribolube stands out head and shoulders above the rest IMHO. Best regards.
thank you for sharing the fruits of some obvious long and hard work. It's interesting to see the difference in levels of effort to get the results between these 2 materials. I've already seen some others mention it, but sending samples of it to Gamers Nexus would be a great idea for testing. LTT has the larger following, but Steve at GN really does have the equipment and methodology to test these claims more thoroughly.
@@mytech6779 Peer review and recreation of results is the cornerstone of the scientific method. It's part of the reason why sending samples to LTT is mentioned. I don't doubt the sincerity of the claims or the work done to achieve these results. But any informed consumer doesn't simply take the manufacturers word. You look for the review from trusted third party sources.
@@ericepperson8409 to be fair neither Gamers Nexus nor LTT have very scientific testing setups. What they do have is knowledge about real world performance testing. But there is more to test about this than just the thermal performance. Spread, conductivity, changes over time (e.g. drying out), etc. Alex of LTT has already tested the first two, I hope we will get a longevity test as well. Now we just need at least one more tester with a precise thermal testing setup.
I thought the isopropyl on the table was for that use at first. I'd try it with acetone and toluene and use the absolute bare minimum that facilitates mixing by hand to avoid any differential settling of the solid particles prior to the vaccum chamber. It would have to be a very low amount too to avoid depositing a super thin film of highly flammable Al powder on the sides of the mortar.
I would go a step further and suggest that it may be possible to achieve a thinner layer during application with the addition of some volatile compound. It's worth exploring.
cool seeing the ultrasonic rod i´ve recommended, it´s a bliss working with them, they make for some efficient and fast extraction, but the noise is worse than fingernails on blackboard
@@jaro6985 we use it in food chemistry analysis to speed up the process of extraction, for samples like fat in cocoa beans, caffeine in coffee beans, trans-fat-acids in all kinds of edible oils, pectine extraction. or to speed up chemical reactions, it uses less energy than a soxhlet extractor. it is also used to clean up some nasty organic residues, a cool multipurpose machine, though watching a soxhlet doing it´s thing is very relaxing. like everything in life there are trade offs
You are absolutely the best expository teacher I've ever encountered. I believe that Prof. Richard Feynman would highly approve of your style. Bravo on your most excellent work. How I wish I had had such teachers when I was in school. Perhaps I would not have been so thoroughly bored with school by the time I graduated.
Two years ago, but still one of the best you have done. Speaking for my son. You do a very good job of explaining difficult things in a simple, interesting and educational way. Wish I had a hint of this ability that you have. Well done !!! 👍
The long term stability of your compound would be interesting. Some of these commercial products just fall apart and seperate into cookie dough after a year or so, which causes them to fail, with very expensive consequences. Could not help smiling when you turned on that "hacked" compounding machine. Your distrust of the device was very obvious :-). I'm familiar with that...
Most times, when the paste 'drys' out it is still fine but only when it is disturbed that you get issues, eg the need to reapply over just gooping it back to the middle and locking it down again.
Depends on what you use. I just disassembled a ~10-y-o machine and the paste was still gooey. Granted, it was a white paste from very old scythe cooler, so probably less effective compared to current mixes.
Watching these videos always makes me feel smarter. Half the time I have no clue what you're talking about but you do such a good job explaining things I feel like I do.
Check out pottery shops and ceramics supply stores. They often have many of the compounds needed for experiments that don't require medical or food grade ratings. Sometimes you need to learn alternative names or the raw ore forms to get a "good enough" alternative.
@@djdjukic Wow, according to my Civilizations III chart, without pottery you're somehow in the stone age with internet access - weird. At least you now know a potential business opportunity that could provide several jobs and further the arts.
Another fascinating video! Though usually quite good, the voice audio is quite low in this one. I took a look at the audio track and though it is normalized, it has quite a bit of dynamic range and likely needed to be compressed to bring up the voice volume, which seems to average -21dB or so. Environmental sounds like the Newton's Cradle create peaks that likely pushes the average down. I had to apply quite a lot of range compression (-24dB knee, 1:5 slope) and re-normalize to get the voice volume near normal to my ear, but I admittedly don't produce youtube videos and don't know your workflow. Even a -18dB knee with normalization afterward noticeably reduces the peaks. This would be done before mixing in the music, of course. Music suffers if over-compressed, but spoken word tends to benefit. Thanks for the great content!
Yes, I agree there is something wrong with the audio here. It sounds a bit like automatic gain control in reverse, resulting in an overall low volume except on voice peaks which are excessively boosted. An odd effect.
It's always fun when you're forced to up your volume, forget about it, then blow your eardrums off when you visit another video! D; Excellent videos however, I absolutely love it!
Please sell more of your stuff in your shop! All I see is a wooden computer and thermal paste. DIY kits would be amazing! You could piece together kits with suppliers and take a handsome margin from the value you created by making it easily available. I think most of us viewers would happily pay a little extra to support you! And we don't really want to go through the trouble of sourcing... Not every country in the world has the ease of access to raw materials you seem to have, so this would be a great high value service you can charge for! Anyways I really enjoy your videos and the detailed explanations of complex projects. Thank you for not dumbing it down too much!
Expensive thermal compound makers: "Nooooo, you can't just undermine our entire business model!!1!" Tech Ingredients: "Haha, science go brrrrr." Seriously though, love these videos and look forward to the testing by LTT and hopefully, Gamers Nexus!
i agree that LTT would make a great video and i would enjoy watching it. but gamers nexus, on the other hand, man id love to see him get ahold of this paste and run some test.
Love your projects. Your authenticity and passion for learning & experimentation is refreshing. Subscribed! ❤ *By the way,* for future videos, can you keep the zoom dialed back a little during nearby shots? Even for closeups, it's good to show a "stage" so viewers can see what is holding up an object (like a hand, a stand, or portion of table) plus items like meters/sensors. It's just a bit too zoomed in sometimes - typically during handheld shots. Remember, you can always digitally zoom in while editing, but you can't zoom out after the fact to show more of the scene.
This very much reminds me of experimentally finding how much oil a given pigment can absorb back when I was learning about paints in university... and also the problems with dispersion of small particles because dispersing pigments is very much an issue when you're mixing paints from pigment.
The consistency of the paste at the final mortar and pestel stage reminded me of chocolate grinding. I think a 'chocolate melanger' aka 'wet grinder' could work as a cheap solution. Though a problem might be the minimal quantity of product required for the mill to work.
Given that a lot of them have lids that seal tightly, I'm curious if you could just dump the final weight of all ingredients into the melanger and just set it to running. Since they're designed to run continuously for hours, it should be able to manage integrating and de-clumping even the finest of the metal powders.
@@mndlessdrwer This would only work for the largest size powder, I highly doublt it would be sufficient even for the intermediate size. Like he said you simply cant mix nano size powders with normal mechanical means, doesnt matter if you mix 1 hour or a decade.
This stuff should always be compared to Dow Corning 260. It's the standard for conduction cooled devices where high voltage is in use, such as conduction cooled power tubes and power transistors.
Love this channel, youre partially responsible for me rediscovering my creative drive as a hobby inventor! Im for sure not the first one to think about this, but using the Kessler effect for a weapon that can be used as deterrence against an enemy invasion, is much cheaper and quite easily accessible compared to nuclear weapons for dictators all around the world ;P
This was mentioned a lot in the comments on your previous video, including by me. Linus Tech Tips are kid-tailored. They do very little deep-diving on anything and stick to flashy catchy topics. Steve at Gamers Nexus is the proper guy to test this.
Understood. However, they were kind enough to review our thermal epoxy last year and based on the much greater interest in a non adhesive thermal paste we wanted to get their feedback regarding our new material.
@@TechIngredients It’d be nice to see a review from both. After all, I’m assuming the point of this experiment/video is to educate people on how potentially overpriced high-end TIM is. GNs viewer-base would love that type of content. Edit: GN* not GM.
@@Mikkel111 Often when someone in a comment section labels unlabeled acronyms it's so other people who are ignorant of the subject matter don't need to look it up. I was ignorant about what TIM meant, and trying to save other similarly ignorant people some time.
We should let this genius try his hand at any problem thats plaguing the world. Not only would he find a solution but he'd create an awesome video of how he did it and share it with us.
I was thinking the same thing. My initial suspicion is that you could just put all the ingredients in the right proportions into a small ball mill and let the thing run in a vacuum chamber. I expect you would end up with the same or better results.
I'm so glad you guys have been able to partner with LTT! Have you reached out to some of the other major computer hardware youtubers, like GamersNexus or MKBHD?
Video idea: vegan leather, you can make it using mushrooms mycelium, or using SCOBY (Symbiotic Culture of Bacteria and Yeast) it is the starter an somewhat of a byproduct of the production of kombucha. I was experimenting with the SCOBY because I was searching for plastic alternative, but mine grew to thick (1.3-1.5 cm in 2 weeks) and still decided to dry it, the one made using honey was stiff, but the one made using mollases as a cheaper alternative of sugar, was leather like, and I want to improve it but I don't have the time to do another experiment. I think it's very interesting and would be a good video idea
Do know that there are plenty of coatings which could be used to waterproof the vegan leather, because placing two sheets of vegan leather overlapping eachother causes them to end up glued to eachother, but soaking them in water unglues them. Not only that, but one might be able to add very thing plastic fibers or metal wires or both into the vegan leather, to significantly increase it's strength. Also, it would be interesting to see what are the possibilities of having the parts which need to be sewn together placed in a container where more of that liquid gets used to have the two margins organically welded together. If it's like glue, then causing some shredding on both ends prior to adding them to the container could increase the strength of the weld. Also, it's easier to grow more material than needed and remove some around the weld area, than to not weld enough and have the product tear from the weld.
@@SapioiT yeah i also made a coating, first i buffed the surface with avocado oil, or any oil high in unsaturated fats, then i coated it again in a mixture of beeswax and pine resin. Maybe I should've used the coatings they use for leather bags, but the thing i was researching for is biodegradability and long lasting in the right condition (e.g. in your drawer, above desk, and places with some sunlight, or places you store leather wallets/bags). But that second coating kind of ruined the leather like texture of it, and that's where I think they could improve it. Although for general purpose like only a splash of water or just sweat, just buffing the surface with oil is enough and without ruining the texture.
Vegan leather is the most stupid term I have ever heard. It's like "Vegan Hamburgers" that taste just like meat. Why would a Vegan want something that tastes like meat? Why would a Vegan want something that is like leather? Very strange and illogical people.
@@johncoops6897 I agree with you there, but the thing is that term is (as of now) the most widespread and agreed upon for leather-like material that isn't from "animals"
I'd be very interested in seeing how the addition of graphene affects concrete properties in your ultimate concrete video. The first couple commercial uses of "Concretene" has just been poured this year in the UK and was developed here in Manchester. Supposedly can increase the strength by 30% for the same cement content and speeds up curing time + other benefits.
Love your videos! One question though, is the thermal compound electrically conductive? one would think with aluminum or copper it would be. Another great job can't wait to see what's next .
I would be interested to see this tested as well. It's worth noting, though, that similar commercial compounds containing metal powders, including silver, are not conductive, just capacitive. There must be enough of the silicone oil between each particle to prevent conduction.
@@slimal1 arctic's "silver" paste also has conductive silver, but its not conductive. amount of conductive material is way too small to make electrical path
Why do you use Aluminium powder and not Copper powder? Since you said in the beginning that Copper has a higher thermal conductivity than Aluminium, I would expect that Copper should work better.
copper and aluminum can under go galvanic reaction under certain conditions. aluminum powder between aluminum heatsinks is adequate enough for this application
I'm not sure galvanic reactions will ever be a concern because this is all a suspension in a non-polar solvent. I imagine copper would be significantly more expensive.
Would these pastes work in the temperature range of liquid nitrogen? If so, they could be quite interesting for people racing for overclocking records.
Superb video! At the start I was thinking no way there's any sense to create over 45 min video about this but you pointed me wrong. The important point of this video is to understand that using just particles of identical size is actually much worse for performance than using mixture of different sized particles.
Man how did I just spend 45 minutes watching a video about making your own thermal paste. This was fascinating and informative from start to end, can't wait to see what other topics you've covered. Thank you for sharing your knowledge with us!
I really enjoyed this video. I used to hate chemistry because of how teachers rush to force the information into our minds, making it seem worthless. These types of videos showed me a more in depth description of what you can do and how it works. You didn't just say that it works. You explained why and how. That made it more of an actual informative video. I'm definitely watching more of your videos to help me understand physics and chemistry better. Thanks for helping the community!!! As a lot of the comments suggests, you are what our high school physics teacher was supposed to be.
You absolutely deserve any possible effort that will help you devlop, and not only gather funds to cover the cost of equipment shown, but also to earn decent income out of all the brilliant work that you do. Therefore, going "commercial" with your inventions is the best idea ever. All the best and good luck. Greetings from Poland (by the way 😉), yes we watch you and we admire you here too.
As a kid, going to school was my least favorite thing to do. I couldn't wait to be done with it and never go back. But you sir, make me want to do it all over again, but only if you're my teacher. Not sure if you already have, but a colab with you and @nilered would be awesome. Keep up the great work.
Nearly perfect video. (Volume issue is only problem, trivial really.) Master class in how to do it right. As a viewer I feel respected, and that's extremely hard to do. Hyper ethical and effective way to promote yourself and your work. Three parts mainly: Transparency of business model, Open source DIY hackable alternative, and An actual product for those willing to pay for convenience.
I think there would be real potential for another version of the mix-at-home kind. If people that use thermal paste often, like repair shops etc, can buy a self mix kit for a liter or something for a fraction of the price of artic silver, but it performs the same or better... I mean... You'd be a hero! (I don't know the results of the last video by heart, maybe this cheap paste already outperformed it)
I remember watch CPU "lapping" videos several years ago and always wanted to try it along with getting a super thin layer of compound. This is awesome.
I hope that you make a fortune with your thermal paste. You are very thorough and scientific in your approach to things. I really appreciate your videos, and I always recommend them to my friends.
Check out the first video on our Thermal Paste if you didn't see it already! 👍 ruclips.net/video/Glfak2B9J5U/видео.html

Did you test using peppermint essential oil pure concentrated inside your paste?
I was just interested to see if you were using toothpaste cuz you had toothpaste sitting on your counter last time and if so maybe the active ingredient of peppermint is what's giving you the ability to make this work.
I'm glad you were showing this video without any secrecy. You say water is the most thermally conductive of liquids but what about gasoline... gasoline is kind of like peppermint oil maybe it's not the purpose to find something that's naturally cooler maybe these liquids don't conduct thermally as well...

Hi, compounding pharmacist here! Tips for those using the mortar and pestle: start off with small quantities of stuff you need to pulverize or mix, then start adding in larger and larger quantities stepwise to avoid clumps and ensure uniformity! Adding all at once will especially make the fine powder just puff up on you and you'll have a cloud of material on your work surface!
Same when making glaze for cinnamon buns. People can't believe that a thimble full of liquid can mix a bowl full of powder!
Im a german pharmacy student and alot of the stuff he is doing, really reminds me of compounding lab back at uni, pretty interesting how that pharmaceutical knowledge can be applied in a totally different field
Something kind obvious but everyone forgets those things sometimes. Not me. Lol .. JK
I wonder though, if I don't have access to the fancy machinery... could I feasibly make this thermal paste with just the mortar and pestle?
@@herrpez No. You could do the two largest sizes by hand, with enough time and patience. But the surface tension of the oil is too high relative to the particle size on the nano particles, so you'll get clumps that don't suspend properly (think hot chocolate powder at the bottom of a cup). You *might* be able to thermally excite the nano particles enough to break that up. In the same way the sonicator imparts thermal energy, imparting thermal energy causes vibrations that disrupt the surface tensions. But that sounds like a good way to make a big mess. Just going with the two largest size particles is likely to get you about 60% of the way from the cheap to the expensive product in performance, which is likely enough for most applications.
Please send this to Gamers Nexus as well as Linus, Steve is one of the best when it comes to methodical and thorough thermal testing.
Tech Jesus testing this would be great.
I actually hope GN goes through the process of making at least the cheap one.
Just Steve. Linus thinks changing DNS server "gives you better wifi".
Yes, they have specialized equipment that could thoroughly test the thermal compound

This dude overclocked his solder paste mixer. That's the coolest thing i've seen in a while.

This reminds me of a lecture on densification. The professor starts by adding golf balls to a bucket and asks the students. Is the bucket full? Some of the students say yes some say no. The prof then adds small bearing balls and ask the question again. The student mostly agree the bucket is full. The prof then adds fine sand and asks again, is the bucket full? Yes the students say. The prof then pours a pint of beer into the bucket. He asks what does this demonstrate. The students postulate and hypothesize. The prof says he is impressed with their answers and then exclaims what this proves conclusively is.
There is always room for beer!
And then he goes and makes cider.
LMAO
This was demonstrated to us by a pastor in church about 10 years ago. Instead of beer, he added water as the last part but I don't remember anymore what he said about it.
@@Dark_eVader he conclusively proved water is inferior to beer?
@@Dark_eVader Same, except lemons and grains of rice. The rice was supposed to be our unimportant interests and daily life, and the lemons were big Christianity.

I'd rather him sing more gospel for a hour than call me out publicly ...
This guy just matched Noctua (one of the best thermal paste on market) in his FIRST attempt!!! Der8auer is sweating right now Lol. I hope you continue to improve and make it better and beat Noctua by a huge margin :)
I agree with the people suggesting sending some samples to the channel "Gamers nexus". They run comprehensive and thorough tests which I think meshes well with your type of videos. They also aren't afraid to tear you a new one so be aware they'll be brutally honest with whatever result they may reach, good or bad. Though I have confidence in the thermal compound you've made here.
tech ingredients testing is far more methodical than anything GN can come up with. tech ingredients guy is literally a scientist and is more experienced giant in comparison to GN
@@lordjaashin Probably, but the relevant comparison here is between GN and LTT, since not only independent review is needed to gain more credibility but these other guys might be more knowledgeable in software test suites and can potentially test in a wider range of scenarios. Also tech ingredients seem to want the additional reach that these guys can provide.
@@lordjaashin GN is arguably the best independent outlet doing testing specifically for PC hardware. They have the flatness measuring equipment, pressure testing, dummy CPU heat load to control for CPU power variability, and they're working on getting a thermal chamber to control for ambient temps, which is on par with, if not more thorough than the testing in the previous video. LTT will just slap it on a CPU, maybe.....MAYBE turn of dynamic boosting in BIOS and record temps while running some benchmarks.
They both have their place on the platform, but GN has a much more scientifically methodology than any other PC tech tuber out there, hands down.
@maxpower1819 Excitement or thoroughness; you can't have both.
But then again, maybe you can ... I dunno
Honestly, they could just make it themselves and test their results
This is the most honest and best explained request for subscribing I've ever seen. I'm in.
As an engineer, I really admire your work.
I wonder how large is the team behind the videos, they are really well prepared and amazingly well explained.
You must have some bloopers, it can't be that much perfect all the time :D
@@adolfocervantes41you just didn't get the joke
The amount of education you pack in each video is incredible.
I feel like I'm at University taking a top level lecture and the best part, is free.
Thanks so much for the amout of effort you put in your videos, I really like the videos you make.
This is one of the highest quality channels that I've run across. Tech Ingredients and Applied Science's channel are the two top tier science channels on RUclips. Great stuff!
By way of a request, could you do a video on making expanding polyurethane foam, which, coincidentally is the opposite of this one on thermally conductive paste? I've had no luck at finding info on it and would love to see how it could be DIY-ed since it so expensive commercially.
My friend has a spray foam insulation business and I worked with him for a number of years as well as partnered with him for a time. It's not too complicated as there are only 2 parts; isocyanate (iso) and a resin. I'm not certain how easy it is to acquire those for ordinary people but it's probably not. They are pretty toxic by themselves (not immediately life threatening unless ingested but not something you want to be exposed to regularly) and when combined they off gas fairly toxic fumes as part of the chemical reaction and foam making process (off gas = "air" bubbles = foam). Once the reaction is done it's safe though, it's just polyurethane plastic. The resin compounds vary a bit by manufacturer and to buy them require licensing and are sold with each brand's iso even though it's more or less the same (the point being getting iso by itself from these companies isn't very easy). Even if it turns out to be relatively easy to obtain and produce your own resin blend and iso, using it to insulate something won't be so easy. The parts are only liquid when separated and once combined quickly start turning into plastic foam. The reaction only speeds up with heat and mixing which you'll want to incorporate because incomplete reactions are bad (toxic chemicals remember). A large portion of the expense for commercial spray foam is the equipment to apply it and the experience of the insulator. The equipment is purpose built and expensive. Where anyone can install batt insulation with a knife, staple gun/ hammer tacker and a ladder, a spray foam rig is many MANY thousands of dollars. You need a plural component propportioner (google that if you're interested), related pumps, hoses and "gun," heavy duty air compressor, sufficient generator to run everything (~40KW), a method to transport all this equipment, and relevant safety equipment (toxic chemicals remember). Not knowing what you are doing can lead to too many problems to list. None of them are anything you'd likely be willing to live with because you DIYed it.
If you have a small area to do, a products like Froth-pak exist but seem unavailable right now. These aren't cheap either and if you need more than 1 or 2 it'd probably be cheaper to have professionally done anyway. To try and replicate these for a DIY method of application is also likely far more costly than it's worth.
Unfortunately, not everything can/ should be DIYed. But I would be more than interested if Tech Ingredients proved me wrong in this case.
@@houndofhysteria2327 Thanks for all that insider info! Very helpful!
@@SapioiT Thanks. Sounds interesting. I'll check it out.
NileRed did something similar when he turned plastic bottles into foam.
I believe some of of the precursors for the synthesis of the components of expanding foam are toxic (cyanide derivatives) and are tightly regulated. It would be difficult to do the subject justice without an industrial account / licence with one of the few manufacturers.
Synthesising the ingredients for making your own precursor and doing it long way to prove it is possible albeit difficult and uneconomical is more Nile Red than Tech Ingredients.
I'll say it again, this man possesses the ability to articulate exceeding that of my professors or the chief chemists with which I have associated. It is a thrill to listen as sometimes complex subjects are explained simply.
Most teachers regurgitate the book like they are reading to a child. They don't express it in their own words because they either don't truly know it, or because they expect students to not read the book and not want a parent figure in the classroom. I hated school for this very reason - it is a waste of time if you read the material unless you have an actual teacher and not someone just wanting a job.
These videos are pretty much well written lab report... but in video format. im all for it.
I just want to say that I truly appreciate the amount of respect you show to the viewer. Both in respecting their intelligence, and their wallet. It's one of the things I appreciate most about this channel, and the cool things you make.
What I love about this video is that it is not just mix this ingredient with that. You will also get an in depth explanation of why certain ingredients are chosen. Thank you
Wow... Just Wow... This is how a demonstration is done properly. I can't even imagine how much effort is put into this content. Priceless.
Thanks
There was a lot.
Love it! Going to echo what so many have said about Gamer's Nexus. They have extremely stringent test methodology. They have a dummy CPU heater to control for normal CPU power loads. They do flatness testing as well, so they'll be able to use it on the flattest IHS and heatsink cold plate they have. (they're also working on getting a thermal chamber for controlled testing, too.) :)
I would love to see GN test "both" compounds vs the usual assortment, and the new lab that's in the works will allow them to control the environment far better than the current segmented office building rental. At the bare minimum, Tech Ingredient's explanation of thermal pastes is vastly better than anyone else's aside from maybe Buildzoids explanation of the maths of thermal resistance under the IHS vs direct die for LN2 overclocking.
GN aren't going to impartially test anything. Their test setup is only to demonstrate the superiority of their sponsor's thermal interface product.
'They have a dummy CPU heater to control for normal CPU power loads'
I’ve always loved your videos. You’ve genuinely helped me think, scientifically, about everything around me. I’m listening to this video on my own DML speakers that have phenomenal performance for pennies. And the best part about them is that I know exactly how they were made and how they can be improved upon. Please don’t let anyone or anything stop you. You are helping my children learn how to think and process and create the world around them for the better.
Wow, thanks!

That sort of detail opens if a lot of ideas when I watch your stuff, so it is really appreciated.

thank you, good health to you and your loved ones from South Africa
Another great video. It's interesting what you said about the zinc oxide (neat vs silane treated) having lower viscosity when mixed with the silicone oil. I think you said that the silane coating on the zinc oxide was supposed to make it more hydrophilic. My understanding is that most (all?) metal oxide surfaces are already hydrophilic because they form hydroxyl groups on their surface (the surface hydroxyl groups are what the silane compounds bond with). In my experience, silane treatments on metal oxide particles are typically to make the normally hydrophilic metal oxides more hydrophobic (by including a hydrophobic group in the silane molecule) for better dispersion in organic solvents. So if your silane coating was actually hydrophobic it might explain the improved dispersion of the zinc oxide in the oil and the lowered viscosity. If the silane is hydrophilic it would be interesting to try and figure out why the viscosity is going down because that seems very counterintuitive so the explanation should be surprising.
The scientific accuracy over all your videos is quite impressive and enjoyable. Only few take the time and pay such attention to detail in order to achieve this level. Thank you for this amazing high quality content, please keep up the good work. Now I just need to come up with a reason why I should order a few kilos of your thermal paste to support you ;)
Спасибо большое, что делитесь информацией и даже помогаете советами, хотя, по сути, это продукт ваших трудов, интеллектуальных терзаний и огромного количества потраченного времени. Я поражён вашим умением объяснять технически сложные термины даже для такого человека как я, я не очень хорошо знаю английский и изучал язык по сериалам и кино.
В общем, удивительно, что вы распространяете полученные знания, за это вам моё уважение!
thank you for being who you are. you are a great teacher.
Thank you for the most informative videos! I have 2 comments that might help. 1) I made a pourable KNO3/Sorbitol propellant by using about 30% powdered and 70% 200 mesh KNO3, heated with Sorbitol at a 65/35 O to F ratio. Initially it is as thick as stiff mashed potatoes. I then add 0.2% surfactant ( Polystep B1) and the mixture thins out enough to easily pour! It is like magic!
2) Using multimodal powders, surfactants and mixing under vacuum can greatly reduce the viscosity of a high solids mixture. I make pourable mixtures of powders and polyurethane with up to 88% solids using trimodal powder mixtures, mixed in steps. I mix using a Red Devil 1 gallon paint mixer and a stainless steel beaker with a lexan lid which I attach to a vacuum pump. I only use 1 mix container so there is no loss between process steps.
Note, this probably won't work in batches too small on the Red Devi.
Another vote to send this to Gamers Nexus. They do thorough, scientific testing with lab equipment. I love LTT, but it seemed like they really flew by the seat of their pants for their video on your thermal epoxy.
Ok.
@@TechIngredients woot!
That was part of the point of the video though. Alex was just going ham doing that most pc enthusiasts. I do agree that it's needs more extensive testing.
I concur Gamers Nexus is far better at testing things than LTT. If you wanna be able to put numbers up there that PC builders will under and know they are the way.
Link to LTT video ruclips.net/video/75AhrTQWs70/видео.html
It would be interesting to see your thorough treatise of ptfe greases, and their properties. I recently encountered a use case where they were involved, and unintentionally opened a pandora's box. There are various compounds commercially available, all resembling what we would call a ptfe grease, but their properties, and quality vary from one end of the spectrum to the other. High-end (and very expensive) products like Krytox, Christo-Lube, and Tribolube are a world apart from bicycle shop products, even though its not immediately obvious why this would be so. Even the expensive ones vary considerably. They are typically used as oxygen/nitrox safe lubricants for gas cylinder threads and O-rings, amongst others. I'll bet any money you have at least one of them in your lab/shop over there :-). For what its worth, Tribolube stands out head and shoulders above the rest IMHO. Best regards.
thank you for sharing the fruits of some obvious long and hard work. It's interesting to see the difference in levels of effort to get the results between these 2 materials. I've already seen some others mention it, but sending samples of it to Gamers Nexus would be a great idea for testing. LTT has the larger following, but Steve at GN really does have the equipment and methodology to test these claims more thoroughly.
This channel actually has the proper thermal test equipment and tested a range of pastes in the last 6 months.
@@mytech6779 Peer review and recreation of results is the cornerstone of the scientific method. It's part of the reason why sending samples to LTT is mentioned. I don't doubt the sincerity of the claims or the work done to achieve these results. But any informed consumer doesn't simply take the manufacturers word. You look for the review from trusted third party sources.
@@ericepperson8409 to be fair neither Gamers Nexus nor LTT have very scientific testing setups. What they do have is knowledge about real world performance testing. But there is more to test about this than just the thermal performance. Spread, conductivity, changes over time (e.g. drying out), etc. Alex of LTT has already tested the first two, I hope we will get a longevity test as well. Now we just need at least one more tester with a precise thermal testing setup.
This was the coolest freaking video I have seen all year, science is amazing. I subscribed to your channel!
Welcome aboard!
Great video. I especially appreciate your description of heat and sonic energy at the beginning.
Thank you.
I was wondering if you could speed up the mixing by an addition of a low boiling solvent that would be removed at the v-pump
I thought the isopropyl on the table was for that use at first. I'd try it with acetone and toluene and use the absolute bare minimum that facilitates mixing by hand to avoid any differential settling of the solid particles prior to the vaccum chamber. It would have to be a very low amount too to avoid depositing a super thin film of highly flammable Al powder on the sides of the mortar.
I though the same thing.
maybe acetone? i think it would evaporate in a couple of hours at worst.
I would go a step further and suggest that it may be possible to achieve a thinner layer during application with the addition of some volatile compound. It's worth exploring.
Was thinking the same thing. Maybe a little camp stove alcohol or acetone
cool seeing the ultrasonic rod i´ve recommended, it´s a bliss working with them, they make for some efficient and fast extraction, but the noise is worse than fingernails on blackboard
What do you use it for
You need a cabinet for it, lol.
I've never run across one in operation, but with first-tooth experience with an ultrasonic dental scaler, I'd definitely trust you on that.
@@jaro6985 we use it in food chemistry analysis to speed up the process of extraction, for samples like fat in cocoa beans, caffeine in coffee beans, trans-fat-acids in all kinds of edible oils, pectine extraction. or to speed up chemical reactions, it uses less energy than a soxhlet extractor. it is also used to clean up some nasty organic residues, a cool multipurpose machine, though watching a soxhlet doing it´s thing is very relaxing. like everything in life there are trade offs
Would a sealed glass jar in an ultrasonic cleaner work the same?
For some reason this really reminded me of those educational videos from the island.
You are absolutely the best expository teacher I've ever encountered. I believe that Prof. Richard Feynman would highly approve of your style. Bravo on your most excellent work. How I wish I had had such teachers when I was in school. Perhaps I would not have been so thoroughly bored with school by the time I graduated.
Thank you!
I've heard him speak. That's a huge compliment.
Two years ago, but still one of the best you have done.
Speaking for my son.
You do a very good job of explaining difficult things in a simple, interesting and educational way. Wish I had a hint of this ability that you have.
Well done !!! 👍
The long term stability of your compound would be interesting. Some of these commercial products just fall apart and seperate into cookie dough after a year or so, which causes them to fail, with very expensive consequences. Could not help smiling when you turned on that "hacked" compounding machine. Your distrust of the device was very obvious :-). I'm familiar with that...
Most times, when the paste 'drys' out it is still fine but only when it is disturbed that you get issues, eg the need to reapply over just gooping it back to the middle and locking it down again.
Depends on what you use. I just disassembled a ~10-y-o machine and the paste was still gooey. Granted, it was a white paste from very old scythe cooler, so probably less effective compared to current mixes.
Nice! Been waiting for this!
Really great video, I was looking forward to seeing how it was made and you were very clear and explained the process and reasoning well.

Another fascinating video! Though usually quite good, the voice audio is quite low in this one. I took a look at the audio track and though it is normalized, it has quite a bit of dynamic range and likely needed to be compressed to bring up the voice volume, which seems to average -21dB or so. Environmental sounds like the Newton's Cradle create peaks that likely pushes the average down.
I had to apply quite a lot of range compression (-24dB knee, 1:5 slope) and re-normalize to get the voice volume near normal to my ear, but I admittedly don't produce youtube videos and don't know your workflow. Even a -18dB knee with normalization afterward noticeably reduces the peaks. This would be done before mixing in the music, of course. Music suffers if over-compressed, but spoken word tends to benefit. Thanks for the great content!
Yes, I agree there is something wrong with the audio here. It sounds a bit like automatic gain control in reverse, resulting in an overall low volume except on voice peaks which are excessively boosted. An odd effect.
Glad I'm not the only one. Thanks for pointing this out! I had a hard time watching the entirety of this video due to the audio issues.
Agreed - it's as if the compressor is working in reverse, to expand the dynamic range. A difficult listen this time (but not usually).
It's always fun when you're forced to up your volume, forget about it, then blow your eardrums off when you visit another video! D;
Excellent videos however, I absolutely love it!
Please sell more of your stuff in your shop! All I see is a wooden computer and thermal paste.
DIY kits would be amazing! You could piece together kits with suppliers and take a handsome margin from the value you created by making it easily available. I think most of us viewers would happily pay a little extra to support you! And we don't really want to go through the trouble of sourcing...

*By the way,* for future videos, can you keep the zoom dialed back a little during nearby shots? Even for closeups, it's good to show a "stage" so viewers can see what is holding up an object (like a hand, a stand, or portion of table) plus items like meters/sensors. It's just a bit too zoomed in sometimes - typically during handheld shots. Remember, you can always digitally zoom in while editing, but you can't zoom out after the fact to show more of the scene.

This very much reminds me of experimentally finding how much oil a given pigment can absorb back when I was learning about paints in university...
and also the problems with dispersion of small particles because dispersing pigments is very much an issue when you're mixing paints from pigment.
This boiling water demo is a really great demo. Something you wish you could have seen in middle school science class.
Been looking forward to this.
The consistency of the paste at the final mortar and pestel stage reminded me of chocolate grinding. I think a 'chocolate melanger' aka 'wet grinder' could work as a cheap solution. Though a problem might be the minimal quantity of product required for the mill to work.
Given that a lot of them have lids that seal tightly, I'm curious if you could just dump the final weight of all ingredients into the melanger and just set it to running. Since they're designed to run continuously for hours, it should be able to manage integrating and de-clumping even the finest of the metal powders.

Video idea: vegan leather, you can make it using mushrooms mycelium, or using SCOBY (Symbiotic Culture of Bacteria and Yeast) it is the starter an somewhat of a byproduct of the production of kombucha. I was experimenting with the SCOBY because I was searching for plastic alternative, but mine grew to thick (1.3-1.5 cm in 2 weeks) and still decided to dry it, the one made using honey was stiff, but the one made using mollases as a cheaper alternative of sugar, was leather like, and I want to improve it but I don't have the time to do another experiment. I think it's very interesting and would be a good video idea
Do know that there are plenty of coatings which could be used to waterproof the vegan leather, because placing two sheets of vegan leather overlapping eachother causes them to end up glued to eachother, but soaking them in water unglues them. Not only that, but one might be able to add very thing plastic fibers or metal wires or both into the vegan leather, to significantly increase it's strength. Also, it would be interesting to see what are the possibilities of having the parts which need to be sewn together placed in a container where more of that liquid gets used to have the two margins organically welded together. If it's like glue, then causing some shredding on both ends prior to adding them to the container could increase the strength of the weld. Also, it's easier to grow more material than needed and remove some around the weld area, than to not weld enough and have the product tear from the weld.
@@SapioiT yeah i also made a coating, first i buffed the surface with avocado oil, or any oil high in unsaturated fats, then i coated it again in a mixture of beeswax and pine resin. Maybe I should've used the coatings they use for leather bags, but the thing i was researching for is biodegradability and long lasting in the right condition (e.g. in your drawer, above desk, and places with some sunlight, or places you store leather wallets/bags). But that second coating kind of ruined the leather like texture of it, and that's where I think they could improve it. Although for general purpose like only a splash of water or just sweat, just buffing the surface with oil is enough and without ruining the texture.
Vegan leather is the most stupid term I have ever heard. It's like "Vegan Hamburgers" that taste just like meat.
Why would a Vegan want something that tastes like meat?
Why would a Vegan want something that is like leather?
Very strange and illogical people.
@@johncoops6897 I agree with you there, but the thing is that term is (as of now) the most widespread and agreed upon for leather-like material that isn't from "animals"
@@aiki6378 - LOL... that is absolutely ridiculous.
I'd be very interested in seeing how the addition of graphene affects concrete properties in your ultimate concrete video. The first couple commercial uses of "Concretene" has just been poured this year in the UK and was developed here in Manchester. Supposedly can increase the strength by 30% for the same cement content and speeds up curing time + other benefits.
I always learn something new with each of your video. This channel is a rare gem on youtube
I had no idea how interested I was in homemade thermal paste until now. My mind is blown. You are my favorite engineer. Thank you for the knowledge!
Love your videos! One question though, is the thermal compound electrically conductive? one would think with aluminum or copper it would be. Another great job can't wait to see what's next .
I would be interested to see this tested as well. It's worth noting, though, that similar commercial compounds containing metal powders, including silver, are not conductive, just capacitive. There must be enough of the silicone oil between each particle to prevent conduction.
Our paste is not electrically conductive.
@@TechIngredients Nice.
Have you tried measuring it's capacitance? Bare silicon dies don't like capacitative pastes.
@@TechIngredients how is that possible? It's got copper and aluminium in it. Please do an explainer video. Thanks
@@slimal1 arctic's "silver" paste also has conductive silver, but its not conductive. amount of conductive material is way too small to make electrical path
Why do you use Aluminium powder and not Copper powder? Since you said in the beginning that Copper has a higher thermal conductivity than Aluminium, I would expect that Copper should work better.
The material it's being used on is aluminum. Aluminum and copper can have a reaction.
@@marcostreet3169 depends on the cpu cooler though, some have a copper contact plate, other an aluminum one.
copper and aluminum can under go galvanic reaction under certain conditions. aluminum powder between aluminum heatsinks is adequate enough for this application
@@marcostreet3169 Almost all CPU heat spreaders and heatsink cold plates are nickel plated copper.
I'm not sure galvanic reactions will ever be a concern because this is all a suspension in a non-polar solvent. I imagine copper would be significantly more expensive.
Would these pastes work in the temperature range of liquid nitrogen? If so, they could be quite interesting for people racing for overclocking records.
I suspect there might be problems with the compound shrinking vs the metal surfaces at LN2 temps.
My guess is that they would become too brittle
You're a master scientist and teacher. One channels with the best content on internet. You have got a Follower instantly
Superb video! At the start I was thinking no way there's any sense to create over 45 min video about this but you pointed me wrong.
The important point of this video is to understand that using just particles of identical size is actually much worse for performance than using mixture of different sized particles.
Would you be able to add an evaporative solvent for better mixing purposes, that flashes off during the vacuum stage?
I thought that was what he was going to do in the first step... mix it with Isopropyl to make a slurry, then evaporate it out after mixing
linus tech is a waste of paste compared to gamer's nexus lmao
Man how did I just spend 45 minutes watching a video about making your own thermal paste. This was fascinating and informative from start to end, can't wait to see what other topics you've covered. Thank you for sharing your knowledge with us!
Thanks.
The topics are the vehicle and the principles are the purpose.
I really enjoyed this video. I used to hate chemistry because of how teachers rush to force the information into our minds, making it seem worthless. These types of videos showed me a more in depth description of what you can do and how it works. You didn't just say that it works. You explained why and how. That made it more of an actual informative video. I'm definitely watching more of your videos to help me understand physics and chemistry better. Thanks for helping the community!!! As a lot of the comments suggests, you are what our high school physics teacher was supposed to be.
Thank you!
You absolutely deserve any possible effort that will help you devlop, and not only gather funds to cover the cost of equipment shown, but also to earn decent income out of all the brilliant work that you do. Therefore, going "commercial" with your inventions is the best idea ever. All the best and good luck. Greetings from Poland (by the way 😉), yes we watch you and we admire you here too.
As a kid, going to school was my least favorite thing to do. I couldn't wait to be done with it and never go back. But you sir, make me want to do it all over again, but only if you're my teacher.
Not sure if you already have, but a colab with you and @nilered would be awesome.
Keep up the great work.
This might be, hands down, the best RUclips video I've ever watched.
Thank you!
Nearly perfect video. (Volume issue is only problem, trivial really.) Master class in how to do it right. As a viewer I feel respected, and that's extremely hard to do. Hyper ethical and effective way to promote yourself and your work. Three parts mainly: Transparency of business model, Open source DIY hackable alternative, and An actual product for those willing to pay for convenience.
Thank you.
Wow.... truly amazing. I have just realized why there are very cheap and very expressive thermal compounds.
Love how you went over the densification process. The thermal results were quite good too.
My favorite channel to watch at 2X speed. Thank you for making this, it was very enjoyable. May have to grab a tube of the HP paste.
I think there would be real potential for another version of the mix-at-home kind. If people that use thermal paste often, like repair shops etc, can buy a self mix kit for a liter or something for a fraction of the price of artic silver, but it performs the same or better... I mean... You'd be a hero!
(I don't know the results of the last video by heart, maybe this cheap paste already outperformed it)
I remember watch CPU "lapping" videos several years ago and always wanted to try it along with getting a super thin layer of compound. This is awesome.
I wish I had this man as my teacher all through my years in school.
I hope that you make a fortune with your thermal paste. You are very thorough and scientific in your approach to things. I really appreciate your videos, and I always recommend them to my friends.
Thanks!
