@@Spiralem That'd be pointless, since mercury is actually a very poor thermal conductor.

I think he kind of adressed this by talking about the water content of the honey, as long as the compound doesn't lose its fixitive ( like with water evap ) its thermal properties should remain

@@crashoverride93637 Evaporation isn't the only concern. Does it slowly react with metals normally used in PC components? Does it oxidize? How quickly? How does temperature affect all of those factors? An endurance test shows you what reality's doing to undermine you. Sometimes it takes a while for those effects to become apparent.

Since the motivation for this project was the apparent lack of public data on the topic, I'm guessing the reason why he's sharing the formula free of charge is so that the time and competence of other people will scrutinise their compound and find its actual properties.

@@Teth47 much like Tesla and fsd the best way to do massive scale testing is to have users do the test by putting the formula out there anyone can do the testing for massive scale

For Overclockers there is only the peak performance. so honey will do.

Correct, this is a time zero test. When validating thermal solution it is temperature cycled to accelerate life degradation. Another important aspect is measurement account part to part variability.

Took the words right out of my head!

This is very important. I've seen compounds degrade over time and some of the cheap ones even leaking out from under the heatsink which led to thermal shutdowns. I generally stick with NT-H1 / H2 or ArticSilver MX. The latter will retain its properties for years and makes taking off a heat sink easy.

@@1MRSomeguyunless we're talking about personal lubricants I fail to see the relevance of sexual preferences. After saying that I now have a very uncomfortable mental image of Linus using thermal paste as lube. Someone pass me the eye bleach, please.

The question is: Is it really necessary to control it to that point? Measuring temperature difference between the two sides after it has settled should be perfectly sufficient. As long as all thermal pastes are tested the same way (i.e. same surfaces, same pressure, same input (heat) power etc) it should be easy to find the best (and get a good indication by how much).

@asdrubale bisanzio Steve does pretty well controlled tests. Nothing on this level, but pretty good for determining real-world performance in a typical use case. Linus on the other hand veers more into the entertainment side of things. Still fun to watch, and not entirely useless info, but a lot less controlled.

@asdrubale bisanzio But is it actually important to keep the temperature of one side constant if you are only interested in the temperature difference between both sides? Actually it would be much more accurate and repeatable to measure the temperature difference only and let the experiment run until the temperature difference has settled. Instead of introducing additional inaccuracies from the cooler, measuring the 12 minutes and so on.

It actually got my hopes up that they had gotten a solid sponsorship. Was a bit sad they didn't.

And one with some kind of thermal insulator (sort of a "worse than nothing" test), so we can get a better sense of the scale of the results.

I agree, but how accurate of a test would it be given the bit about surface imperfections and small contact surface area?

Yes! Negative controls are super informative and basically essential. Surprised it wasn’t shown. I bet they did this at some point.

@@JustinWillis_actual it would show how good the surfaces already where and if the thermal compounds where acting as insulators. Thinner the better the more perfect the two surfaces are. It's probably a huge variable in how you should choose your compound for the job.

Its liquid Metal not this what Linus used in the no moving parts PC

@@Comedy4noobs he did use LM for that video but linus did a shout-out referencing this video.

Which LTT video? can you give me the link with timestamp?

@@tafsirnahian669 Recent one with the passive cooling.

Link?

In a discussion between Steve of Gamers Nexus and Der8aur, they discussed how different thermal compounds have different thermal conductivity at different temperature ranges. For example, "liquid metal" is outstanding at high temperatures, but performs terribly when cold, so it is useless when cooling with liquid nitrogen. Fortunately, we can all do our own tests and share our results!

That's a great observation, I came to the comment section looking for this. Taking into account the potentially compounding variability in the readings of the temperature sensors monitoring the water inside the chiller, the air inside the enclosure and the metal cylinder conducting the heat towards the interface, I also believe that 0.1-degree differences between test results are not statistically significant. I am not dissing the design of the equipment or the thought process behind the test methodology. I just think that the test in its current form does not have a sufficiently high discriminating power, and also is not particularly relevant for the product application that was hinted at in the video (namely, a thermal compound for use in a personal computer). Aiming for a higher temperature delta between the cooler and the temperature probe would likely increase the discriminating power and the relevance (as relatively modern processors can easily exceed 50-60C while operating with a run of the mill water cooler) - that could be achieved by pumping more power into the resistors to heat the cylinder. The radiating heat from the cylinder would then likely become an issue at higher temperatures, but that could be controlled with an AC feeding air to the enclosure. Also, this test is essentially evaluating the kinetics of energy transfer and doing so by taking a single point of data on the timeline (well, actually 2 points if you consider the starting temperature and time). While I understand the time constraints - these tests are already lengthy as they are, and everything from building the equipment to filming and editing takes a lot of effort (thank you for that btw) - I believe that the results would be more relevant if they would consider starting and ending the tests closer to equilibrium conditions. This would of course greatly increase the time required for each test and would involve careful tweaking of the power of the heating element and the dimensions of the cylinder that transfers said heat to match the capabilities of the cooling element. All in all, I would love to see a collaboration video with Linus, or Steve at Gamers Nexus, and will consider buying your thermal compound for my next build (as soon as you get some stability data on it as well).

@@benedictul Yeah, pretty much agree with this. This would have likely been solved if they ran the tests in the higher temperature ranges, since the temperature equilibria at higher ranges would also be higher as long as the heating doesnt overload cooling potential

If Professors = Professor's then videos = video's

Professors are employed for their research output and ability to attract funding - not their skills in teaching adults undergraduate courses. Generally professors make the worst teachers at any education level

It's because it's not his job... Every time I've had a hobby that I was great at (IT work, photography, RC, etc) that people started paying me to do, I quickly grew to hate the hobby. Maybe I am strange in that way, but I suspect this is a big reason a professor learns to stop caring. A bunch of 20-somethings that are aimlessly drifting through life would quickly wear on me as well.

@@jacobwcrosby Have you tried working for yourself where you have the freedom to accept or reject work/clients? It's a little bit like musicians that have given up creative control (sometime copyright) to the recording and music industry. This has happened to the biggest musical acts - even the Beatles. I recall George Michael's dispute with Sony. The company would not release George Micheal from his contract so that he can collaborate with other artists, so Michael stood down from any music for a few years until his contractual obligations with Sony lapsed. He hated the music industry at the time (and probably until his death). I tend to agree with you though - money and external non-creative demands often contaminate the passion and creativity that drives a hobby. There are some artists and scientists etc that have managed to avoid these pitfalls.

"Chill" - LOL. I see what you did there! :D

I get that well-executed scientific methodologies are rare on youtube but I feel like he was actually making a really good point rather than an unknowing meme. It's a testament to his scientific rigor that he understands their test setup's merit is only as good as its ability to stay consistent with itself and when compared to other's test results rather than just assuming that he really did account for every variable imaginable or that the experiment happens to be designed soundly just because it seems that way.

@@Chris-io2cs of course - I just found the intonation on 'pretty good' hilarious.

I think the tedium you are referring to is precise attention to detail.

Synonyms for "tedious" in this context: Rigorous, thorough, precise, meticulous, scrupulous...

Yeah, I missed the temp level but if he was pushing 100C it would be interesting, seems my old CPU that plays RU-vid videos at a temp of 34C Plays other games at up to about 72 which is a bit over the recommended value of 66. But if I push it harder and it gets into the '90s my computer says that enough of that silliness and shutdown :( Now I mean I'm glad it shutdown because otherwise, I would have already had to buy a new CPU, but this did make me wonder about changing my factory Heatsink for a replacement with a bigger heatsink, pumps and grills and all that seems like too much for me, but a big heat sink and a quiet fan would make me happy, my fan case has actually blown all its fans but the CPU and Video card fans are still working :)

@@basildaoust2821 If your CPU is getting so hot that the system shuts down it's likely that one of three things isn't working properly anymore - either the fan isn't spinning as fast as it should, the fins of the cooler are filled with dust and debris, or the thermal compound between the cooler and the CPU die has dried out (could be all of the above). Also, if the case fans are not spinning, you are not getting enough fresh cool air to help with cooling your CPU, video card and other components inside the case. If you don't feel like changing the case fans, I would recommend removing a side panel and keeping it off so the hot air inside the case at least has someplace to go. Then take your CPU fan off (remember the orientation) and take a vacuum cleaner or compressed air to the fins to remove the dust buildup, then screw it back on and see how it goes (you don't have to take the cooler off the CPU in order to do that). If this doesn't help with your CPU temperature, then it's probably time to change the thermal compound, as it might be dried and cracked and effectively insulating the CPU instead of helping dissipate the heat. This is all assuming that your cooler isn't seriously underspecced for your CPU, in which case you should look for a better alternative, however, you might as well try the inexpensive solutions first.

@@benedictul Yeah I don't think the issue is any of that, it's just if I push it too hard it gets mad. I mean my case fans have died and I have a house fan blowing air through the case with the side panel off. The CPU fan and the video card fans are working just fine. I have a new CPU that is much better, not good compared to the new ones but more than twice as good as my old junk. So yeah the plan is to first run the one or two games that complain at lower graphic settings which does work quite well while I buy a few pieces to put the new system back together. The change does also let me switch to an m.2 drive so I expect some nice improvements. Thanks for the suggestions.

I just discovered Breaking Taps a few days ago, and WOW. That channel is going to explode. Also, Huygens Optics is good.

AGreed there, I was just going to suggest a temp logger. But You can also chart the temperature inside the Arduino. (I wouldnt use ESP32, they don't tend to have very good built-in ADC's. And, if you use a digital temp sensor like DS18B20 , I have noticed that they tend to be +-3 F cyclically, which requires a ton of averaging. ) I found Arduino's ADC and a simple PTC thermistor to be the best of the bunch

@@gutrali I was thinking they could interface with their existing high-accuracy scientific equipment. It's pretty common for it to have some kind of digital interface. If not, I think the built-in ADCs on both boards are pretty garbage, better to grab an external ADC on a breakout board or something.

There's a link to the results in the description.

@@gutrali What is the effect of the ADC on the ESP32 not being good? Also, aren't they suitable for temp dataloggers?

@@Z3DZ3R0 they are suitable but it depends on your requirements. Check this out. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UAJMLTzrM9Q.html I had so many problems calibrating an RTC thermistor until I started to use an external ADC. I'm not sure but I think the Wifi onboard the Esp causes some voltage spikes that will affect your ADC readings. Plus it's 10 bit and only 3.3v

I was wondering this too. Would be nice to have the control temp to see how it compared.

Modern CPUs can even runnwithout any heatsink on them (throtling down so far that they're basically unusable, but still running), so I'd say the temps aren't an issiue, but the clocks the CPU will run at.

@@Donnerwamp True, but the default surface on CPU's and heatsinks are nowhere near as flat as his test rig. A few of the 'lapped' setups on RU-vid would probably be pretty close, but true lapping with wavelength precision like he was talking about is nearly never done on CPU or heatsinks at least on RU-vid. (Literally only 1 video with no numbers posted) His test rig is not true lapped, but that's fine.

For reference, I agree this would be interesting. Also, just for reference, why not use a drop of water.

Must have been a good day, at least 2 people drinking and doing science [and who knows what else...].

Thanks. They don't if you really understand the principles.

True PCMR replaces Thermal paste each times he boots up the PC

@V0LDY So ... once every two years ?

This immediately entered my mind as well. How chemically stable is it, and if not how long before it begins to degrade as it undergoes thermal stress? How long before I'll need to remove and reapply it, and could it potentially begin to set and harden over time and require specific chemicals in order to remove it? If it does degrade over time, could it potentially harm the CPU lid?

@@HallsteinI guess we will know in the next video where he teaches how to make it

Most thermal pastes use vegetable oil (ie the stuff you use to cook your eggs) to keep from drying out or polyethylene. You can literally take a couple drops of glycerin (vape juice) and mix it with toothpaste and you have the standard thermal paste that dell etc uses. He has obviously done the research and knows what is needed or he wouldn't sell it.
