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).

[@ParadigmUnkn0wn]

@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.

[@Mike-oz4cv]

@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.

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).

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.

[@basildaoust2821]

@@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 wish I had a science or engineering teacher like you when I was in college, I guarantee I wouldn't have fallen asleep in class. Great content! Suggestion: for all the effort you put into the thermal test, you could have used a thermometer with an extra digit of accuracy so there would be more than 1 count difference between all your samples.

[@huistv2005]

You probably would. Thats the power of editing video. But the alcohol they didn’t drink, but you can, would make it more endurable ;-)

[@klausbrinck2137]

an extra digit of accuracy would be telling as of the comparison between the different pastes, but would still be practically not-interesting... 0,01°C-difference isn´t gonna make your overclocked CPU feel any difference in longevity or performance. So, althought u r right, this change would only raise the "thrill-factor" and production-value of this test itself (raised production-value pays for enhanced thrill-factor), without any other practical significance.

[@JamesBailey123]

Great video and work as always. I feel like you've missed some important properties that should be measured: 1) How much does it 'dry out' / oxidise over time (sometimes can be simulated with elevated temperatures) 2) Some compounds need a couple days to reach peak performance, including AS5, how bout testing after a week? 3) Feel like you need to have sandwiches that hold the different compounds over time rather than always scrubbing them. The interfaces to the sandwich could be designed around them or just all ultra smoothed lapped so it's not performance limited there. 4) I haven't used AS5 as my premium compound in a decade, I use IC Diamond (tiny diamonds) for some installs and Thermal Grizzly's Conductonaut (liquid metal) if it doesn't eat into the heatsink. You're not exactly comparing against cutting edge? 5) The performance of a lot of these pastes will be somewhat muted in practice because many Intel chips have poor thermally conducting heatspreaders with middling thermal paste over their silicon. Would be interesting to do a die delidding or lapping in combination and see how that goes. 6) For ultimate performance, I'd have a delidded CPU with a Graphene horizontal thermal transfer sheet (can't transfer vertically but does great horizontally), then have lots of holes with a silver sheet overlaid including silver going into the holes to provide vertical transfer, and so that the heat distributes at a fantastic rate over let's say 6cm X 6cm, and the silicon die is already incredibly smooth (but not always flat, can be lapped), then the Graphene sheet has enough compliance not to need thermal paste (still good to test), then a heatsink bonded to the silver layer with a liquid metal thermal interface. If you do that, now that would be world record impressive and a heck of a video!

[@TechIngredients]

As a filler material, graphene is not good as I'll explain in the next video. If price is no object (and it always is) then we have some disk heat sinks with grown vertical arrays of carbon nanotubes that rival bulk diamond for heat transfer.

[@Donnerwamp]

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.

[@BlackHeartScyther]

@@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 KZbin 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 KZbin. (Literally only 1 video with no numbers posted) His test rig is not true lapped, but that's fine.

If it does degrade over time, could it potentially harm the CPU lid?

Those outperform normal pastes by a lot. And so they'd outperform this. They have like 6 to 30 times higher thermal conductivity, depending on what paste you compare them to. Also, they didn't make the best thermal paste until they beat Thermal Grizzly Kryonaut, the best paste I can think of.

[@TheBackyardChemist]

One more factor to ponder about: perhaps the optimal thermal paste is not the same for a pair of polished flat surfaces, as for two much lower grade (rough, non-flat) pair of surfaces. Thermal paste composition is usually a tradeoff between thermal conductivity, viscosity, etc. It is plausible that the optimal viscosity is different.

[@sRoGoRs]

The same thing that was going through my mind and why a control run with no compound would have been helpful.

[@gordonborsboom7460]

How reliably could you clean a rough surface between tests of different materials? Polished surfaces at least give you a fighting chance at removing the previous material. This is a test of thermal pastes and not of surfaces. That would be a separate video all together. He was careful to ensure the paste flowed out around the test cylinder under the spring load, displacing the air, which would minimize the effects of the different viscosities of the pastes one would think (I’m not an experimenter, so I may be overlooking something)

[@TheBackyardChemist]

@@gordonborsboom7460 Hmm, cleaning would indeed be a challenge. My point is that in pactice, the surface of an IHS is neither flat nor mirror smooth, and depending on the cooler it might be even worse.

I was also thinking the "curve" of the logged data.

[@Kizron_Kizronson]

I wonder if the honey performed so well, because some of the heat energy was "used" changing the viscosity. I know it's not a full phase change but It did make me wonder if a substance that changes viscosity with temperature actually "uses" energy to do so. I had a brief (a couple of minutes) poke around on google to see if viscosity changes use energy or not but found nothing useful.

[@masonfreedman]

Viscosity is a property due to the intermolecular forces, as is the specific heat capacity of a material. For nonmetals, as temperature increases, some of that energy is stored in the intermolecular bonds which will also affect the viscosity. I would expect the specific heat capacity change over the temperature range in this video to be relatively small and insignificant. While this test did not reach steady state, it is not a short duration test, so changes in heat capacity should make little difference. The amount of thermal interface material vs the power going into the system is small. Another effect might be the viscosity directly affecting the film thickness for a given pressure, but I can't convince myself either way of its effects.

[@lordjaashin]

honey is thixotropic substance and yes they do take in energy when they change their viscosity state.

I think he stated the indium sheets required a large amount of pressure to work effectively. I expect the springs in his testing apparatus don't apply 1/4 ton of clamping pressure which he stated is the minimum for indium. The liquid metals also have a secondary effect where they can permanently change aluminum (they are intended for use with copper). Using a liquid metal that flowed into the aluminum structure of the test rig would change/invalidate subsequent tests performed before since a surface wipe won't remove the liquid metal.
