Damn fine stuff Sorin.. As I always say you're a great teacher.. this really opened my eyes to preventative maintenance.. I can never thank you enough for all you have taught me..
I've been cooling my power supply too. I bought a tiny mains AC to 12VDC power supply and a bi-metallic switch. I stuck the switch in between the fins of the heatsink so it connects the 12V line when the heatsink is getting hot. I drilled a few holes into the bottom and top of the power supply and stuck a fan on top of the heatsink which is now being switched by the bi-metallic switch. Works amazing. I am sitting there, 6A@14V... the fan turns on, runs for a while, turns off again... super neat.
Perfect. I'm doing the same things to some of my electronic tools and specialy to my DIY projects. Good to see I'm not crazy and someone do it too :-)
Sorin, what have you done? With this video you have successfully transmitted your obsession 😂. Now I'll have to open up everything I buy just to make sure it lasts! Have recently started watching your videos and I have to thank you for sharing. Keep up the good work!
I thought I was the only one who did this. Especially for laptops, I really like to buy different sizes of thermal pads and use a thermal camera to see where the hottest spots are then apply to that area. Great video!
Sorin, I have a really nice Denon audio-video receiver. 11.2 channel, multi room, Bluetooth, WiFi, like ten HDMI ports. Every possible connector. Heavy like a bag of stones. Massive heatsinks and the thing gets hot like crazy. Unbelievable that they don't put a fan inside. If you open it you void the warranty but if you don't, it will die in 2-3 years.
I have an old Lenovo laptop that worked on charger only for 12 years. The battery is still great because it was taken out of the laptop when not used and it was stored in low temperature. The charger on those gaming models died afte Ra few years but mine is in great condition because the power brick always had two old aluminum CPU heatsinks on the charger. It works even through plastic and it keeps the charger cold. Usually they would get hot.
I have a pc which PCH (Northbridge, SATA controller chip) gets really hot. It has a heatsink, but no fan. Temp could go till 60 °C (140 Fahrenheit) when I check my drive speed for example. I added the small Noctua 40×40×10 fan. It fits like a glove between the heatsink and the graphics card. With this mod, the temp cannot rise above 40 °C (105 Fahrenheit). Thank you for the great video Sorin! Make more like this, very enjoyable to watch.
In 2013 I bought an MSI Apache High End Gaming Notebook for about 1300€ and it still runs cool, fine and stable and it does, so I think, just cuz I took it apart 2 times every year for maintenance, brushing dust from the heatpipes and out the cooling-sink, out the fan, its housing, the whole case and I also refreshed the thermal paste. Many Gaming-Notebooks I know and I heared from had died would do so as well, but if not maintaned the dust gets stuck just everywhere and thats mostly a dead sentence by an incoming overheat-damage. It even gets worse when you're a smoker and do so while using your electronics. A smoker I'd advise for doing like me as well, but twice as often. Maybe undusting every 3-4 month as smoked dust is hell of sticky. It actually glues that smokedust into your electronics and the longer you wait, the more sticky it gets. I love my electronics and taking care of it is fun for me every single time. I really appreciate your channel and the way you transport your knowledge straight to us. Please keep doing so.
Yes, that's what I do. Make everything run cool and get rid of the heat. Add extra heatsink or make air flow better with extra hole. But I just know that add more solder will help too. Thank you Sorin
Interesting notion adding the heat pads as a design improvement, though I’d be wary of doing so whilst under warranty though I used to open up everything as a kid just to see what was inside 😅 Makes sense to prolong longevity as best as possible beyond this however - does seem a bit excessive (obsessive!) in some of those examples though 😉
I love your videos ❤ I did the same with a PlayStation did put a big termopad on the memory chips and it is be quiet after it and is cooling down so nice. No noise what is normal. Bu better
Sorine... Nu m-am mai uitat la telenovele de la Sclava Isaura... Dar la postările tale ma uit mai ceva ca la telenovele. Ești de nota 10.(desi inițial am crezut ca ești rus 😃)
Bosorogii la putere:))) o sa caut si eu ceva cu " inventiile mele " sa ti trimit :) doar pe noi ne duce mintea la asa ceva. Eu le fac asta dupa garantie ( nici chiar ca tine ) ... cat sun in garantie le las in pace sa nu o pierd :)
I didn't think those thermal pads were any good. I'll need to buy some. I've got some projects for it. About adding solder. I also like to scrape off the paint from the traces and solder in some thick wire (whatever fits). The added copper will help wick away the heat.
I would say if there are things that are obviously getting hot or are well known to die, or that it is an easy enough job to improve their cooling, I just go ahead with that. For example old laptops with nvidia or ATI chipset that can go bad, I just replace their thermal pads with copper shims right away. I also have a BMS chip on an aftermarket battery that tends to overheat, I put thermal pads on top of that chip and then cover the top plastic with aluminium tape to dissipate the heat.
Do the thermal pads conduct heat longitudinally over their lengths? I was always told they were supposed to be between the device getting hot and the heat sink that would dissipate the heat, the thermal pad being an electronic insulator and if an insulator wasn't needed, neither was a thermal pad and simple heat sink compound could be put between the device getting hot and the heat sink. To use a strip of the thermal pad on its own, in free space as it were, does that actually conduct sufficient heat to cool hot semiconductors onto a plastic case???
I also make some pics of the electronic board and keep them with the manual in a cloud folder. If a component dies at least it helps me identify the blown part.
It is truly love. There is nothing worse than when a gadget fails at the most critical moment. Better to be safe. Am very grateful to you Sir, for this top advice. Thank you Sir, and stay well.
Sorin, about your bench multimeter, would it also need cooling pads? where would you put them? Cause I have an identical multimeter as yours, you know.
i learn something here , Mr. Sorin what is happening with my laptop charger? it would not startup the laptop. I came up with an idea to put the charger in the refrgerator freezer for 10 minuits , then i pluged the charger in and woooo, the lap top startup , i used it for three hours . Thank you for your videos , i are learning a lot from your videos. Pa pa God bless.
Yup. HP 4320s which belongs to my mother had a very bad heat issue. The video chip (some amd from 2013, you know what i mean) can get very,very hot, especially during games. This happened because two thisngs: 1. GPU and CPU (quite hot i5 480M) are on the same heatpipe. 2. GPU connected thru 2mm thermal PAD, not a heat-transfer paste. Solution was found in placing copper plate instead of thermal pad. GPU temps got down from 105C on GPU to like 60C. The downside - CPU gets hotter, like 70-80C, but its fine, its swopable.
Sorin... why cooling down inductors ... I think that is better to cool down mosfets on your laptop. Coils can rsch 55 degree without any modification on them...
Some people say thermal pads from AliExpress aren't good, some say they works. There are many brands, it's difficult to know who to trust. Sorin, which one do you use in your video?
great video due to family constraints its hard to whip out the iron out everytime, can you just replace the solder technique with a big sheet of thermal pad?
I wonder if it could be situations when more would be less. Sorin already hinted to this when he said in a MacBook the SSD heat was sent via a thermal pad to the motherboard and he moved it so that the heat is sent to the case. In another example I have, the Nvidia videocard in a laptop had a heatsink (with thermal paste) and had dedicated videocard memory chips in contact via thermal pads to the same heatsink. I was told because of that the memory chips are running more hot due to the video chip heat and I am better off actually removing the thermal pads since those do not actually produce more heat. In the examples from Sorin, when he places thermal pads around power mosfets, those thermal pads get in contact with electrolitic capacitors. Those are more sensitive to heat than a power mosfet so I can imagine one could make the situation worse if he's not careful while trying to make it better. But in general I agree is better to check inside the electronics and improve cooling where possible.
Hey Sorin, for years i do something similar to my electronic devices. e.g. my cable tv receiver i added a fan on the top and power it with its own usb port. the fan runs very silent at 5V no heat can stay in the case and my devices lives for ever.
Update -- I did check out some videos where semi-pros ran lab tests. Ends up, t-pads can act as "blankets" and increase heat!! So, a quick observation on this subject appears to indicate that like many things, there are good uses and bad uses. So, you might make matters better or worse using t-pads. Testing Required
Sorin please one question which are that fat heatsink pads which you use in video ? is there a way you give us link to ebay or where we can purchase it ? Thanks you very much ! Big fan and student! and what size use use? looks rly fat.
I'm still wondering why the black tape around the USB power supply, I guess is to keep the box closed but why is not closing as before ? Some plastic clips got broken ? Is the PCB inside with added thermal pads slightly thicker and need to be hold together with tape ? Some other reason ?
Fans are great to electronics but not to our ears. I confess that already mounted an resistance in series with the fan to lower the noise. But only in equipment that is not 100% requested. Maybe can be a solution to your linear power supply keep the fan on but in lower speed to not disturb.
Sorin thermal pads are not designed to only be a conductive material and not dissipative as such. What I mean is that it shouldn't be linked to some kind of heatsink? They do not become saturated with heat and function as a blanket?
But they will still make thermal mass bigger and dissipate some of that heat. But of course you try to make them contact something else (backplate, case or even other cooler(part) PCB), He probably did demonstration with that poor transistor just because comments like yours :)
Buna!O întrebare am și eu. Dacă lăsăm laptopul permanent în priză se deterioreza bateria? Știu că încărcarea se oprește automat la 100% dar atunci când e în priză se descarcă și incarca permanent ori se folosește exclusiv curentul de la priza?
have any of you guys tried using “high-temp” hot glue as a way of cooling components? I got the idea from high performance lithium cells that were wrapped in a “phase-changing heat dissipation material”. It occured to me that a high temp hot glue might have the same effect, plus it works great for waterproofing as well as holding together quickly built diy projects. seems to be working really well so far for me.
Hy Sorin. What do you think about using products like "ag thermoglue" with heatsink? (Maybe with small fan too) Is it conducting heat fast enough, and long enough through the years? Have you used this kind of product?
The first thing i did about my psu was to put thermal paste between the diode bridge and transitors against the heatsinks the only issue left is the loudness of the fan but i just got used to it now lol
Și încă ceva.... Din cauza/datorita ție am cumpărat vre-o 10 laptopuri defecte ca să le repar (probabil peste 20 ani când ies la pensie și o sa am timp) 😂
Nah you are not too poor, you are just oldscool, not giving in to the consumer world we have become! You are right, today everything is just made to survive the warrenty with mostly cheap components to make sure you have to buy a new one once those components are at the end of their life. But with a bit of electronics knowledge you can make the lifespan longer for most consumer electronics and the heatpads and extra solderings are surely a nice option.
Dear Sorin the help in dissipating the heat is not always the best solution! Checking your experiment with the transistor I can say that when you use a transistor that can handle only 100mA and you drive almost 220mA for sure will get hot and goes short. Then you used same transistor and you tried to help on dissipating the heat but the transistor still struggle to work in good conditions because is over loaded. and instead using the thermal pad if you use for example a BD237 or TIP31 transistor definitely you will not have this issue with the heat!
Could a circuit board, e.g. from an e-scooter, be filled with resin to achieve maximum cooling? There are companies that do that even with electric motors, they are often cast with resin (stator) What do you think dear Sorin?
filling with resin can help dissipate heat sure, but they don't do it to make it last longer. they do it so you can't fix it. it's a common trick that manufacturers have been doing for 30+ years.
Sorin can I ask you to take a look at something for me? I have a control unit that has blown a component but it’s taken some of the number off! I’d like to send a pic for you take a look at and see if you can see what it does? It’s only a 3 legged component but the power readings is throwing me! Anyway I can send a picture and details??
I put heatsinks on all my tv video boards. tv's are made to fail and the video chip gets _very_ hot. Manufacturers don't put enough heatsinks on purpose so it fails and you have to buy a new tv. Heatsink it all over and it will last many years. Don't do that and it will be dead in 2 years. I also do the same for all my old retro computers because the special chips run very hot and can't be bought so they must be kept cool or they will go to the great silicon grave yard in the sky.
Hi Sorin, l need to ask you a question ⁉️ I connect my DVR in reverse polarity with battery, it's was a little smoke How can l fix it. Is diode or switch. Thanks 👍
You just made people buy thermal pads more than the Ads for black Friday
Love the post💚🧡💚🧡
:) :)
I USE fans every were !
Sorin - I love my electronics, but I love you more for telling me how to properly take care about them!
Thank you very much 🤝

I never seen any of Sorin video that is waste of time. Every single video is a school. Genius
Sorin: "Do you really love your electronics?"
Still Sorin: proceed to kill a poor transistor.
Sacrificial demonstration 😂

Do you have a good trick picking the right height thermal pad? If you put too much thermal pads, you bend the pcb, then cracked joints appear...

This is pure gold in a video.
You will tend to find those pads in old large plasma TV's.
🙏💚🧡 Sorin, my chinese tablet, an octo-core never get hot, as in reading your videos, So I Love it!🧡💚🧡💚🧡💚

Best recommendation ever, be cool, make your devices cooler than cool

I bought a mini PC without a Celeron fan
That's what I did on the first day
I received it today oh my life five years
That scratch on your new desk bothers me! Can you wood stain it please 😂
i have been doing that for long time & its rewarding
Actually, what thermal pad are you using? Where have you bought it?
I found out that for CPU the best is PTM7950 from Honeywell (Phase-change materials , become liquid around 60°C nearly as efficient than liquid metal)
Sorin please one question which are that fat heatsink pads which you use in video ? is there a way you give us link to ebay or where we can purchase it ? Thanks you very much ! Big fan and student! and what size use use? looks rly fat.
check ebay amazon, usually i'm buying 100mm x 100mm/ 2mm, 3mm
@@electronicsrepairschool Thanks Sorin I have some 1 and 1.5 idk why but when I watch it on your videos they are looking like 5mm + thick :D
I'm still wondering why the black tape around the USB power supply, I guess is to keep the box closed but why is not closing as before ? Some plastic clips got broken ? Is the PCB inside with added thermal pads slightly thicker and need to be hold together with tape ? Some other reason ?
Fans are great to electronics but not to our ears. I confess that already mounted an resistance in series with the fan to lower the noise. But only in equipment that is not 100% requested. Maybe can be a solution to your linear power supply keep the fan on but in lower speed to not disturb.
What kind of thermal pad do you use/recommend ? (E.g. 6.0W/mK 5mm thick?) (I just discovered this thanks to you!)
Doing this on new products will destroy the warranty and maybe more.
Sorin thermal pads are not designed to only be a conductive material and not dissipative as such. What I mean is that it shouldn't be linked to some kind of heatsink? They do not become saturated with heat and function as a blanket?
The pads make contact with the backplate or whatever, I guess that works as a equivalent of a dedicated heatsink.
But they will still make thermal mass bigger and dissipate some of that heat. But of course you try to make them contact something else (backplate, case or even other cooler(part) PCB), He probably did demonstration with that poor transistor just because comments like yours :)
insane tips man.
Mulțumesc! Chiar îmi pasă de electronicele mele!
A really interesting video, I didn't know thermal pad can do such a great job. Thanks!
Buna!O întrebare am și eu.
Dacă lăsăm laptopul permanent în priză se deterioreza bateria?
Știu că încărcarea se oprește automat la 100% dar atunci când e în priză se descarcă și incarca permanent ori se folosește exclusiv curentul de la priza?
Thanks Sorin,for another imformative video.
have any of you guys tried using “high-temp” hot glue as a way of cooling components? I got the idea from high performance lithium cells that were wrapped in a “phase-changing heat dissipation material”. It occured to me that a high temp hot glue might have the same effect, plus it works great for waterproofing as well as holding together quickly built diy projects. seems to be working really well so far for me.
hmmm????????????

How do i get to meet you in person and have a photo together is this possible ?
Gas is expensive so we can use that heat :)) Educational video like always . Love your work Sorin !
WoOoOoOoOoW very smart idea perfect Love iT
Can you share what kind of heat pads you are using (buying)?
BigClive has also the same obsession. He under-run his LEDs always so that they could run at cooler temperatures and last much longer.
The first thing i did about my psu was to put thermal paste between the diode bridge and transitors against the heatsinks the only issue left is the loudness of the fan but i just got used to it now lol
That's what I always do when I design something: paying attention to keep it cool.
Și încă ceva.... Din cauza/datorita ție am cumpărat vre-o 10 laptopuri defecte ca să le repar (probabil peste 20 ani când ies la pensie și o sa am timp) 😂

I make vents on all chargers. It helps escape heat.
properly calibrated heatsinks everywhere!

I also do the same for all my old retro computers because the special chips run very hot and can't be bought so they must be kept cool or they will go to the great silicon grave yard in the sky.
Hi Sorin, l need to ask you a question ⁉️
