A mug like that would be quite handy during those meetings to talk about how we're going to fix the problem I was working on fixing until I got dragged into the friggin meeting...
your HR skit there at the end is darn near what happened to me a few days ago at work. Our "safety department" is having a new safety slogan contest and were in my departments office along with a few managers and some supervisors. With a dead serious face and an upbeat excited tone in my voice I told them I had the first place slogan and at the very least third place. The safety goons were all smiles urging me to share my slogan. Alright, here it is. "It does the job as safe as it can, or else it gets the hose again" . needless to say they were not very supportive of my slogan and for the next few days I had random people coming up to me asking me about my slogan or to tell some other random dingus they brought with them my slogan. Anyways, I would love one o' dem mugs there so I can stop sniffing the cat box in the mornings to wake up and start drinking coffee instead.
That last one is SPOT on.. Our last HR "person" came to us with a big smile (straight from the military with the whole; "education in leadership" and all), She left with a diagnose and a broken faith in humanity... Serves her well for pestering productive and "value generating" peoples lives..
At least you didn't have a Hazard Chemical Training Person with a degree in Child Psychology who thought she knew everything. Yeah, she didn't last all that long.
Holy-ol-FACK, the Patreon SNR is so amazing that I actually got through to AVE about the crustiness of their TIM-job AND he also went and took the time to make a video about it to spread the knowledge to the rest of the club! Honestly, this community is amazing.
Simon Ashton; TIM =Thermal Interface Material, a.k.a. the white goopy schmoo inbetween two mating surfaces. Similar to other types of hand jobs, the quality of a TIM-job can easily be determined by inspection of the quality (and quantity) of schmoo deposited on the working surface. :)
I used to work in IT. In the '90s, Sun server CPUs used to be shipped with a nifty 1/4" drive torque wrench (calibrated to 5 in-lbs). They were all metal construction, looked like something NASA made, and you could recalibrate them. I had a drawer full of them, but I only kept a few. I haven't actually _used_ any of them... but that's what having tool cabinets are for. HS Schmoo usually comes off with Acetone, but you don't want to be using your "Sunday" shop rag for cleaning it, as like NevrSieze it gets on everything in the damn shop. I'd like a mug, but watching your channel is entertainment enough. (I left Tronna for Switzerland in 1990, so I like hearin the Canajun every now and then.)
Not a bad Bob Ross impression, you know, for a Canadian. :) My 7yo son wants to take everything apart, but doesn't care much for puttin' it back to together. I need a coffee mug to maintain my sanity.
"Keep your Richard in a bad habit" That is the best damn thing I've heard all day! And said so cutely too! Better have the boss do all your tag lines from now on. The mugs look great too.
Cheers from another cold wasteland formally known as Sweden. Regarding how to wipe of the diaper rash creme: In confusers, we use acetone and coffee filters, since it leaves no residue on our CPUs. Also the proper way to apply the new paste is in a single line and then letting the assembly of the component press it out since that leaves no air pockets. On a CPU it can differ 20 degrees Science depending on if this is done correctly. Now as we say in Sweden, Have it nice!
It's actually been shown numerous times that application method has minimal effect on thermals, as well as applying too much does nothing but simply waste thermal compound! GPU manufacturers on high end graphics cards apply a LIBERAL amount, it's almost crazy how much they use but as more doesn't effect cooling, but too little can be critical they do this! (better safe than sorry). Over time and thermal cycling it all flattens down evenly with the pressure of the sync, and just oozes out the edges. I totally agree with your application adivce though a simple line of it down the middle horizontally would have been the way to go (same as the rice grain amount on cpu's).
I wouldn't recommend using acetone since it dissolves quite a few common plastics. Isopropyl is much better as a general cleaning solvent, including electronics, and it also doesn't leave residues. Didn't know about coffee filters, I'll have to try that out.
When the blokes are around ya toast off that mug with your right-but when those clipboard warriors come a-rollin’ you done hold that mug up high for a sip with your left. Here’s to another laugh in the shop!
Dear lord, thank you AvE - you are the first RUclipsr I've seen (including Linus and EEVBlog) who actually understands that the thermal compound is ONLY to fill the tiny voids. You don't need 10 litres of the bloody stuff
Feel free to send a mug my way. Or don’t. I’ll still buy at least one for work. I’ve found arctic silver, while expensive, tends to not dry out too quick. I checked it on a PC I built 12 years back and it was still nice and schmooey.
We got an egghead computer 'zine here in Tschörmeny. Last year they tested all that thermal conductivity schmoo. Way up high ranked: ketchup! Dries out fast but chooches better than some stuff you can buy on that purpose.
Hey AvE, probably better not to pre-schmear the thermal interfiddley schmoo what for not creating bubbles in the middle of the heatsink when stripping the philips heads. Like I tell the wife just leave the schmoo pasted on there untouched gooped in a line in the center as the load will schmear it much better than you by hand.
For large heatsinks like this pre-smearing the heatsink compound is always best in industrial applications where you want to get good consistency from batch to batch. We have certainly had no issues applying it this way in many years of manufacturing high power/heat devices. And when you remove a heatsink it always looks like when AvE pulled the original heat sink off (what he describes as the mars like surface).
I'm no electromagical surface enginerd and I've never dealt with a heat-sink that large. However, while laying TILE, you use a trowel to KEY the mortar. Keying in this way allows you to develop and ensure even DEPTH of adhesive (because the keyways/teeth/notches act almost like a go/no-go, while simultaneously removing excess at high spots and forcing material into low spots). It's essentially a non adjustable metered dispensing unit. The result is a fairly even coating to be squished into a given area. Just food for your big gorilla brains. And, I just read James Banana's comment about applying one thick single line while using the mechanical force of the components to spread it out - leaving no pockets of air. Pretty sure his method makes more sense... Edited to say - I don't think I have commented on your tube before (haha), however I have been watching your content for a long time and want to thank you for being real. I feel that, not only have I learned a lot from you, but you've also proven to me that I'm not weird for thinking the way that I do... Thanks AvE.
nam Sake I was thinking about this too. The difference is that, with tile, you want a full layer of adhesive. With a heatsink the thermal paste is only filling in microscopic cracks on each surface. You don't even have to use paste if you lap the surfaces together.
+William Chamberlain I'm a bit of a carby cleaner fan actually, it just seems to take everything of anything, so it makes it easy to decide what to use. And Shellite is my other favorite cleaner if there is any plastic or melty bits.
Another subtle difference on Hitachi VFD vs others: heat sink channels closed with baffle plate, creating chimney effect cooling on heatsink, fans running or not. 2 hp model could be improved by just sheet of metal blocking backside airflow, creating chimneys of each pair of fins. Non-intuitive, but really werks!
Doc Pedersen I suspect duty cycle has a part to play in the size. I imagine a municipal waste water pump or something similar that cycles and perhaps ramps up to 200% of rated speed on occasion to match demand?
Doc Pedersen my guess was simply that the hitachi has a larger heat sink and active cooling because it may be subjected to more extreme conditions (load and frequency swings).
The “cracked” schmoo pattern is actually a sign of well applied schmoo. You only get that pattern when there’s good schmoo coverage WHEN you pull it off. The pattern isn’t there while the two schmoozing parts are together. Try it out for yourself!
This has probably been mentioned a dozen time already, but regardless, my $0.02 on the thermal stuff: With most chips, the header plate is massive, but you're just interested in where the specific die seats on it. Once you know (or guess) that, apply a pea sized strip along the die(s). The pressure when you crank the heatsink down on the plate is enough to spread it out. and get good enough thermal conductivity. I've seen tests with people using all sorts of crazy things for thermal conduction including peanut butter and all do fairly well. I'd look more at dissipating the heat on the heatsink itself (by a fan, etc) more than getting *perfect* thermal conductivity on the heatsink to the chip itself. All the thermal goo does is fill the pours in the top plate and heatsink surface to get better transfer.
What Kaz said.. specifically the last 2 sentences. I repair servo drives. All the thermal paste is doing is filling microscopic imperfections in the metal to allow better heat transfer. Too much is bad bc you're creating insulation. "A dab'll do ya" is the right way to go. And if it's dried up and flaky, it isn't working anymore.
The fewer barriers/interfaces the better. The best contact would be a weld but once you achieve that you kind of have to start over. Next best would be perfectly fit and polished surfaces with nothing between them.
That would be the computer geeks. Real engineers will buy it in the packaging that is closer to what it really is for a price that isnt marked up more than car dealership motoroil.
When the Xbox 360’s came out and you were sending on back to Microsoft once a month to then just get a pos refurbished one back, I actually took the last one I received apart and used some arctic silver and replaced the fans with some that were not so anemic. It’s lasted over 6 years now, I’d dare say 8.
A mug would be great. Although I can't be sure of my superiors' approval, I've been taught to go for it first and ask for forgiveness later. What's the worst that could happen?
Here's a suggestion about thermal grease from a recently-paroled professional: squeeze a reasonably thick stripe of grease in a line that goes from one screw to the other, and extend the line out paste both screws. Width of said line of grease: maybe 4 mm. As you tighten down the screws, the excess grease will be squeezed out perpendicular to the line and get squirted out from underneath the base of the device. It's clear that the two surfaces make contact near the screws, so the grease layer will end up as thin as it can be, and it will probably cover the entire contact area. Typically, with a square device held in place by weak springs, you can't expect this kind of optimal thinning, and the pros sometimes apply the grease in a matrix of small dots. If your mating surfaces were accurately flat (they're not) and the were clamped with uniform pressure (they're not), then there's another trick you can use to get a uniformly thin layer: Run two pieces of kapton tape along either long edge of the contact area (thickness: about 0.1 mm, just right for silicone thermal grease), put a big blob of grease on one end, and run a razor blade over it to spread it out over the surface. With practice, this makes a uniform layer of thickness 0.1 mm. Last trick: use better thermal grease: Laird T-grease 2500.
Correct me if I am wrong, but in my PC modding days. I read that one can expect about a 50% increase in life expectancy for each 10°C you drop the operating temp for electronics.
That sure sounds like it still is. The surprise recently came from a study from Google? Facebook? one of the big ones surely, stating that that doesn't hold with hard drives as we all used to believe.
There is a rule of thumb in chemistry that for every 10°C increase in temp, the rate of reaction doubles. If parts are degrading due to chemical wear (oxidation etc) then sounds like you might be right!
It is true that lower temperature will extend the life of most electronics as failure rates follow the arrhenius equation. The much quoted doubling in failure rate for every 10C rise in temperature starting at 20 C ambient. However, there are all sorts of caveats, such as ensuring that the temperature is not reduced below the dew point and mechanical parts have problems with lubricant failure at low temperature. However, modern electronics is very reliable, with electrolytic capacitors being arguably the must unreliable component. The real problem with modern electronics is if it contains software, as manufactures are using software to build obsolescence into equipment, usually by ensuring incompatibility with newer versions. A lot of perfectly good and working electronics is consigned to the scrap heap, simply because a computer operating system no longer supports the necessary drivers. This form of obsolescence is creeping into brown and white goods as well as automotive electronics. As internet connectivity is added to almost all electronics, manufactures are using software obsolescence to force consumers to constantly replace products.
Ohhhh fak yeah, I could sport one of those fine mugs around the office... shop..... errr.........probably just walking around the house in my underwear.
a This Old Tony and an Ave vijeo in my box after battling the clip board warriors all damn week; hurray! Just what I needed (along with a couple beers)! Thank you gentlemen.
Hey Uncle B. Here to thank you for another laugh and lecture. Half the time I've no clue what you're talking about. Partly my lack of knowledge in the field, partly the language barrier, don't speak Canadian too good. But I learn a lot and laugh a lot listening to you ramble on. It's that time of year to spread a little extra love around, so I wanna thank you for doing so all year long with your videos. Have a good one Dad.
Chickadee has become everyone's favourite, imagine big laughs behind hundreds of thousands of cockford ollie themed monitors. Even my wife burst when I showed her your pubehairy painter's impersonation! And every laugh makes the world a bit better. Thanks for that!
No love for the Allen Bradley? Well, you know what they say, you can buy a better piece of industrial controls equipment, but you can not buy one more expensive.
"Keep your Richard in a bad habit" That was absolutely the funniest thing I've heard in MONTHS! I come for the learnin' wha, and a laugh or two. But from the Chickadee? Priceless!
So I know in the build a PC community, there are all sorts of this that and the other ways of putting on thermal paste, with each one being morally superior to the next- but it made me think of laying tile and how to properly put down mortar so there are no air gaps and you get perfect coverage. I wonder how those two fields might overlap here since it's the same basic principle.
Its not quite the same principle, though. With tile, you’ll accept air gaps to allow a tile to be in the same plane as the ones adjacent. Mounting to a heatsink, you want both surfaces as close as possible and any air gaps filled with something more conductive than air (down to a microscopic level). I say load her up, clamp her down, heat her up a few times, re-torque, heat her up a few more times, then scrape the excess schmoo off the sides.
Altera Max II CPLD: $7.50 to almost $40 USD at Digi-Key, depending on model. Basically, it’s a programmable logic chip; and is probably implementing some “glue” logic for the main microprocessor that runs the drive. 🤔
I don't think I would like to have to explain that mug to the wife... Depending on surface finish the thinner the thermal paste the better. More metal to metal contact the better as the paste is meant to just fill in the voids on the surface. Most of the time these days everyone just slaps a dollop in there and squeezes her together.
Xylene and better yet, Toluene (if you can find them) will properly act as solvents for silicone oils. "White Spirits" sort of work, but....not that well.
Also try citric acid, theres a well know brand of cleaner that smells of fresh cut limes!!, for removing thermal compound from pc processors, think its made by alaska or akasar?( ive prob spelt both wrong!!lol!) Hope this help for some one. All the best mateys!
White mugs are great. You can clean the schmoo off with bleach and the little lady will never know you had it in the shop. I'll take one if the givings are still there to give.
I just bought an America Rotary static phase converter for my little tiny hardinge milling machine. It's about a quarter of the mazak but it has a Bridgeport high speed c head and a horizontal spindle. It still has the scraping on the ways. I will be the most accurate 16 year old on the internet. That is if I don't break it in a week, fingers crossed.
My ability to invibe tea in the workshop formerly known as garden whilst fabracobbling my latest creation would be greatly inhanced by the addition of a cockford ollie mug. No ones touched my tools since the sticker warning to their tenancy to bite has been applied.Thanks Dan
The ridges from the milling is a result of not doing a small finishing cut when using an end mill. It happens because of tool or material deflection, not the clearance angle of the cutter. That only comes in play when plunging with an end mill, when going sideways the clearance prevents galling and the rotation will ensure a flat surface just like a fly cutter. That’s the only reason the clearance angle is there.
Those big caps reminds me of my dad trying to fix the old tube tv. I told him that that one big tube in its own cage prolly should be left alone, but no, he had to touch the metal clip on top of the tube. Learned a whole lotta new words that day! Btw, would love a new mug for the shop!
If they wanted to keep the electronics running hot, they wouldn't do it by doing a crap job on thermal paste. That doesn't save any money. They'd just give it a smaller heatsink, since that makes it cheaper to produce at the same time.
Being the technical guy in my job I get called for everything from computer freezing to on-site electric machinery fixing, I work in an art shop, I need that mug!
Your little girl is freaking adorable. Keep up the good work. It’s a lot better to raise them right then to trouble shoot problems later. The wife is a psychologist and trying to repair damaged people is a nightmare.
There are different patterns created depending on how dry and crappy the thermal goop is; you can usually tell when it's got some life left by the different patterns you find.
Hey! @4:10 your torque wrist didn't click! Though, honestly, the way the original TIM looked is pretty normal for what most applications look like on the computers I work on regularly. Also, what does Dewclaw think he's doin'? Actually doin' work in the shop?! Would love a Cockford Ollie mug, though I'm pretty sure I'm probably too late to the vidjeo to get noticed. Ah well. Always enjoy your vids either way, and is nice of you to give 'em away. Hope you have a good Christmas!
FAAAAK. Those Capacitor's look like they should scare you as much as that starter motor did... Maybe you should repurpose them into giving the Mrs' filling rattler a little more chooch ;)
I have a guitar amplifier from ~1975 that has caps about that size in it. 8000 uF at like 32 volts. Given how far the technology has come, I suspect those pack quite a bit more punch.
Hey AvE, I know you got mugs and other knickknacks, but I'm still waiting for my "Certified Licensed Diploma in Destructive and Reconstructive Engineering." Is there some kind of form I need to fill out?
Form 93fa-6Z. Its a little hard to find but it should have everything you need. The 93fa-4H may work if you have all supporting documents. Don't go for the 93fa-5G though.
I need that mug for my enginerding cubicle. Desperately.
That would be greaaaaaaat...
I'll go ahead and come in on Saturday to deliver it. PM me your name and addy.
WAHOOO! THANK YOU SIR!
I'm gonna need you to come in on Sunnnnday too. Thanks Peter
Two mugs at the same time, man.
Way to go Lundberg
I told a Chinese co-worker to engage his safety squint's...HR wants to have a talk with me now for some reason.🤔

AuMechanic does vinegar get that silicon off?
I've used rubbing alcohol or hand sanitizer to clean off thermal paste from CPUs and heatsinks with good success
+1 For finger painting the compound. I usually use a sandwich baggy tho, on account of being cheap.

MikeCookie1973 Huh? I was referring to method of getting heat out of heatsink better.....
Doc Pedersen my guess was simply that the hitachi has a larger heat sink and active cooling because it may be subjected to more extreme conditions (load and frequency swings).
I just sat through a 5 minute ad for an oscilloscope because I like this channel that much!
tell chickadee that we say hello, and good job with the outro. :)
Oh man those mugs are awesome. Always wanted some Cockford Ollie in my cup
Paul's Garage Your engine light is on.
Frank Gormanns uh oh, the electrical tape fell off
umm,, did u want to rephrase that??
It puts the schmoo on the heat sink, or it lets the smoke out again.
Chase Konop @AvE lookie here! ^^^^^
The “cracked” schmoo pattern is actually a sign of well applied schmoo. You only get that pattern when there’s good schmoo coverage WHEN you pull it off. The pattern isn’t there while the two schmoozing parts are together. Try it out for yourself!

The enginerds are gonna be mad because you used genero silicone paste and not ARCTIC SILVER PLATINUM TITANIUM PASTE!
Fuck that. Coollaboratory Liquid Pro is what she needs! Only $20 a gram!
Damn straight!
That would be the computer geeks. Real engineers will buy it in the packaging that is closer to what it really is for a price that isnt marked up more than car dealership motoroil.
Getsome Thermal Grizzly Conductonaut $9 a gram! save some denero and chill your sil
When the Xbox 360’s came out and you were sending on back to Microsoft once a month to then just get a pos refurbished one back, I actually took the last one I received apart and used some arctic silver and replaced the fans with some that were not so anemic. It’s lasted over 6 years now, I’d dare say 8.
A mug would be great. Although I can't be sure of my superiors' approval, I've been taught to go for it first and ask for forgiveness later. What's the worst that could happen?

Here's a suggestion about thermal grease from a recently-paroled professional: squeeze a reasonably thick stripe of grease in a line that goes from one screw to the other, and extend the line out paste both screws. Width of said line of grease: maybe 4 mm. As you tighten down the screws, the excess grease will be squeezed out perpendicular to the line and get squirted out from underneath the base of the device. It's clear that the two surfaces make contact near the screws, so the grease layer will end up as thin as it can be, and it will probably cover the entire contact area. Typically, with a square device held in place by weak springs, you can't expect this kind of optimal thinning, and the pros sometimes apply the grease in a matrix of small dots. If your mating surfaces were accurately flat (they're not) and the were clamped with uniform pressure (they're not), then there's another trick you can use to get a uniformly thin layer: Run two pieces of kapton tape along either long edge of the contact area (thickness: about 0.1 mm, just right for silicone thermal grease), put a big blob of grease on one end, and run a razor blade over it to spread it out over the surface. With practice, this makes a uniform layer of thickness 0.1 mm. Last trick: use better thermal grease: Laird T-grease 2500.
That mug is exactly what’s needed on my workbench that way people can see how I feel during our morning “safety” meetings
Correct me if I am wrong, but in my PC modding days. I read that one can expect about a 50% increase in life expectancy for each 10°C you drop the operating temp for electronics.
That sure sounds like it still is.
The surprise recently came from a study from Google? Facebook? one of the big ones surely, stating that that doesn't hold with hard drives as we all used to believe.
There is a rule of thumb in chemistry that for every 10°C increase in temp, the rate of reaction doubles. If parts are degrading due to chemical wear (oxidation etc) then sounds like you might be right!
It is true that lower temperature will extend the life of most electronics as failure rates follow the arrhenius equation. The much quoted doubling in failure rate for every 10C rise in temperature starting at 20 C ambient. However, there are all sorts of caveats, such as ensuring that the temperature is not reduced below the dew point and mechanical parts have problems with lubricant failure at low temperature. However, modern electronics is very reliable, with electrolytic capacitors being arguably the must unreliable component. The real problem with modern electronics is if it contains software, as manufactures are using software to build obsolescence into equipment, usually by ensuring incompatibility with newer versions. A lot of perfectly good and working electronics is consigned to the scrap heap, simply because a computer operating system no longer supports the necessary drivers. This form of obsolescence is creeping into brown and white goods as well as automotive electronics. As internet connectivity is added to almost all electronics, manufactures are using software obsolescence to force consumers to constantly replace products.
This is true for electrolytics, which is typically the part that fails most often, specially in motherboards.
cool (no pun intended) thanks for that.
Ohhhh fak yeah, I could sport one of those fine mugs around the office... shop..... errr.........probably just walking around the house in my underwear.
I work with my brother. One of those mugs could save me the trouble of having to speak dozens of syllables a day.
a This Old Tony and an Ave vijeo in my box after battling the clip board warriors all damn week; hurray! Just what I needed (along with a couple beers)! Thank you gentlemen.
Your daughter is delightful, she reminds me of my daughter when she was that age.
Hey Uncle B. Here to thank you for another laugh and lecture. Half the time I've no clue what you're talking about. Partly my lack of knowledge in the field, partly the language barrier, don't speak Canadian too good. But I learn a lot and laugh a lot listening to you ramble on. It's that time of year to spread a little extra love around, so I wanna thank you for doing so all year long with your videos. Have a good one Dad.
Fack I need a mug it even has a Monday side
Monday side. Yoinks. I'll pay you royalties in mug. PM me your name and addy.
All that fancy info headed your way!
How's about one of the free mugs come my way please.
- A gal that watches AvE and has her own empire of dirt
The guys on the construction site would certainly get a kick out of seeing this mug in my hand. Perfect!
Chickadee has become everyone's favourite, imagine big laughs behind hundreds of thousands of cockford ollie themed monitors. Even my wife burst when I showed her your pubehairy painter's impersonation! And every laugh makes the world a bit better. Thanks for that!
there’s always someone with bigger capacitors
i cant drink coffee ona counta it makes me have to poop. hard.
Tony Fleetwood there's nothing hard about mine after coffee.
Take 20 for safety!
that's why i drink coffee
boss makes a dollar, i make a dime, thats why i poop on company time!
I find choc chip cookies with coffee tends the balance things out.
The wakefeild is good stuff, I use it from time to time on Bombardier's Global's and Challenger's. Typically on the wing leading edge temp switches.
I've said it before and I'll say it again. You, sir, are my spirit animal.
OOH that mug looks mighty fine for telling the collegues where to over the hollidays!
No love for the Allen Bradley? Well, you know what they say, you can buy a better piece of industrial controls equipment, but you can not buy one more expensive.

All-in Ballsdeep
Now all I want for Christmas is a “keep your Richard in a bad habit” t-shart.
STK Hook I will second that
You and I have a lot in common. We both drink out of cups. Look at us!
Looks more like a mug to me.
YOU THINK YOU'RE BETTER THAN ME?!?! DAMN CUPISM IS ALIVE AND WELL... oh. Yeah you right.
Thanks AvE, I can always count on you for a laugh, even when HR tells me to get my stick off the ice.
"Keep your Richard in a bad habit" That was absolutely the funniest thing I've heard in MONTHS! I come for the learnin' wha, and a laugh or two. But from the Chickadee? Priceless!
How feasible do you think a crowdfunded Tesla BOLTR is?
beastly5569 Fuck Yeah! Even if it comes via copart or some other auction, a motor and tranny tear down would be the Cockford Ollie!
The inverter alone is a thing of beauty.
Don't forget, AVE's afraid of schparks. Lots of schparks in that battery...
So I know in the build a PC community, there are all sorts of this that and the other ways of putting on thermal paste, with each one being morally superior to the next- but it made me think of laying tile and how to properly put down mortar so there are no air gaps and you get perfect coverage. I wonder how those two fields might overlap here since it's the same basic principle.
Its not quite the same principle, though. With tile, you’ll accept air gaps to allow a tile to be in the same plane as the ones adjacent. Mounting to a heatsink, you want both surfaces as close as possible and any air gaps filled with something more conductive than air (down to a microscopic level). I say load her up, clamp her down, heat her up a few times, re-torque, heat her up a few more times, then scrape the excess schmoo off the sides.
Preferentially, the chip would be printed directly on to the massive, silver (Ag) heatsink. ;)
Dying here with the Keep your Richard in a bad habit comment, YT video bombing at its finest, Would love a f*** Off mug tho
Thank you for putting the giggle in my giddy-up
Just discovered the channel Cant stop watching. Awesome stuff.
Altera Max II CPLD: $7.50 to almost $40 USD at Digi-Key, depending on model. Basically, it’s a programmable logic chip; and is probably implementing some “glue” logic for the main microprocessor that runs the drive. 🤔
I don't think I would like to have to explain that mug to the wife... Depending on surface finish the thinner the thermal paste the better. More metal to metal contact the better as the paste is meant to just fill in the voids on the surface. Most of the time these days everyone just slaps a dollop in there and squeezes her together.
Xylene and better yet, Toluene (if you can find them) will properly act as solvents for silicone oils. "White Spirits" sort of work, but....not that well.
While we're adding things, trinitrotoluene is less good at cleaning up silicone oils. Unless you use it the other way.
Also try citric acid, theres a well know brand of cleaner that smells of fresh cut limes!!, for removing thermal compound from pc processors, think its made by alaska or akasar?( ive prob spelt both wrong!!lol!) Hope this help for some one. All the best mateys!
HellBilly Austin Arctic Silver thermal compound emulsifier. I use it a lot on my GPU/CPU and it cleans it up easily.
Orange oil too.
@Ilearch n'n'daCorna Oh Hush. It works perfectly well at converting problems to memories.
As a literal safety professional, I absolutely love that mug. Love the vidjeos, man!
I thought it was an awesome mug when I only saw the Cockford Ollie logo. When you turned it around, I realized it was a glorious mug.
I can just imagine surprise of a guy who accidentally shorts out that capacitor with a screwdriver.
Probably gunna melt off the end of the fucking screwdriver with the ark they can produce
I don't think he'll stay surprised for long.
My heart sank just reading this comment.
I think both him and the screwdriver would be headin straight to low Earth orbit
White mugs are great. You can clean the schmoo off with bleach and the little lady will never know you had it in the shop. I'll take one if the givings are still there to give.
PM me name and addy please and I'll drop a note for the fat man to slide one down your stovepipe.
I just bought an America Rotary static phase converter for my little tiny hardinge milling machine. It's about a quarter of the mazak but it has a Bridgeport high speed c head and a horizontal spindle. It still has the scraping on the ways. I will be the most accurate 16 year old on the internet. That is if I don't break it in a week, fingers crossed.
Rowan Dunn Tightest little ways to get your gibs on.
I don't understand how a rotary device like that can have zero backlash. Definitely looking forward to the next vid! Thanks!
My ability to invibe tea in the workshop formerly known as garden whilst fabracobbling my latest creation would be greatly inhanced by the addition of a cockford ollie mug. No ones touched my tools since the sticker warning to their tenancy to bite has been applied.Thanks Dan
Try 91% Isopropyl alcohol for getting the schmoo Thermal Compound off?
Works for me!
The finger cleaning sachets you get from KFC work a treat
Nice coffee. I'm drunk. Yay, internet!
The way we add paste to CPU coolers is a pear sized dot. might try a long bead up the middle
a pear sized dot? or a pier sized dot?
Jegus! How many containers do you use per application?
The ridges from the milling is a result of not doing a small finishing cut when using an end mill. It happens because of tool or material deflection, not the clearance angle of the cutter. That only comes in play when plunging with an end mill, when going sideways the clearance prevents galling and the rotation will ensure a flat surface just like a fly cutter. That’s the only reason the clearance angle is there.
Those big caps reminds me of my dad trying to fix the old tube tv. I told him that that one big tube in its own cage prolly should be left alone, but no, he had to touch the metal clip on top of the tube. Learned a whole lotta new words that day! Btw, would love a new mug for the shop!
Dude, I gotta sleep!
LazerLord10 even so, this takes priority.
LazerLord10 that's what crockford ollie solves
I love your videos AvE. However, I must spend my legal tender buying the love and affection of my wife and children.
Nothing says affection like a Skookum as Frig T-shart or a Cockford Ollie sticker for your child's sticker collection. ;)
I could get a shirt for my wife. She is convinced that AvE is Mike Rowe.
Coffee! I love coffee, but coffee dont love me. It always makes me release the schmoo.
That mug is exactly the right amount of subtle.
Nothing like a good stealth mug for one's coffee spillin' hole. Win or buy, I will have one. Keep up the quality work.
BOB ROSS FTW!!!!!!!
Beat the Devil out of it :D
Happy lil mistakes
ALAPINO Rob Boss.
i like the mug; but I'm left-handed.
There are dozens of us!
If they wanted to keep the electronics running hot, they wouldn't do it by doing a crap job on thermal paste. That doesn't save any money.
They'd just give it a smaller heatsink, since that makes it cheaper to produce at the same time.
Being the technical guy in my job I get called for everything from computer freezing to on-site electric machinery fixing, I work in an art shop, I need that mug!
Your little girl is freaking adorable. Keep up the good work. It’s a lot better to raise them right then to trouble shoot problems later.
The wife is a psychologist and trying to repair damaged people is a nightmare.
Does the shmoo look all mars-scape just because you pull off the heatsink. It's going to look like that no matter how nice you put it on.
Doesn't look that dry
There are different patterns created depending on how dry and crappy the thermal goop is; you can usually tell when it's got some life left by the different patterns you find.
it wasn’t a pattern from tension from pulling on a paste. it’s a pattern of dry cracking
12:03 Got to be one of the funniest things in the world.
Hey! @4:10 your torque wrist didn't click! Though, honestly, the way the original TIM looked is pretty normal for what most applications look like on the computers I work on regularly. Also, what does Dewclaw think he's doin'? Actually doin' work in the shop?! Would love a Cockford Ollie mug, though I'm pretty sure I'm probably too late to the vidjeo to get noticed. Ah well. Always enjoy your vids either way, and is nice of you to give 'em away. Hope you have a good Christmas!
The back of that mug would be perfect for putting the chief engineer in his place in the office!
If you could just slip it in nice and quickly..... the mug in the mailbox I mean! I would love to have a Cockford-Ollie mug!
R.I.P. Bob Ross.
FAAAAK. Those Capacitor's look like they should scare you as much as that starter motor did... Maybe you should repurpose them into giving the Mrs' filling rattler a little more chooch ;)
I have a guitar amplifier from ~1975 that has caps about that size in it. 8000 uF at like 32 volts. Given how far the technology has come, I suspect those pack quite a bit more punch.
in car audio we had 20 FARAD caps. They could weld instantly. it was great.
I found it scary enough changing out a 16uf Cap from a generator.
Hey AvE, I know you got mugs and other knickknacks, but I'm still waiting for my "Certified Licensed Diploma in Destructive and Reconstructive Engineering." Is there some kind of form I need to fill out?
Form 93fa-6Z.
Its a little hard to find but it should have everything you need.
The 93fa-4H may work if you have all supporting documents. Don't go for the 93fa-5G though.
purple won lol
One of those mugs would boost the hell outta the morale round my ranch
This mug has the potential to save lives. I need one!
eeeeehhhh click! You and I have the same brand of fork wrench!
Ooh a new video
Is that mug Metric or Imperial?
no its actually a Pott, a Tasse is a tiny Pott!
Personally, I only need a cup. A whole pot makes me jittery.
definatley love the mug gotta love telling people to get lost in no uncertain terms
holy moly, "Keep your Richard in a Bad Habit" killed me, I've disturbed the whole damned office. So much for covertly watching vi-jay-ohs.
