The Official Thermal Interface Material thread

mechtech · Dec 5, 2022

I have not seen any mx6 yet in Canada. Any consensus on what the best stuff is for longevity and pump out?? I’m looking for something that will last reliably for 6 years minimum before repasting.

mclaren85 · Dec 5, 2022

The best heat transfer (according to thermodynamics law) occurs during the phase change. Which means during the compound melts down or boil etc. (that is the heat coefficient). Also some materials have the "second sound" phenomenon, which enables the heat transfer like a sound-waves do, which is also very important factor to analyze thermal conductivity.

According to this information the best ever paste has to be PCM (Phase change material) type. I don't know it yet to be created, but that is the way the companies should take.

Note: As far as I know, Henkel Industries tries to make some of that type of grease, but for only industrial usage.

PCM?

Currently on it
3600 and 3070FE in a NZXT H210i
Literally the best paste i've used to date. Beats everything i've tried (NT-H1, 2, mastergel pro, MX4, gelid gc extreme, kryonaut, hydronaut, ic diamond and so on...)
Haven't tried TFX yet. Heard they come out of the same factory. Lowest temperatures i had and lowest hotspot difference (9 to 11)
Spread it, let it rest 20m and put it back on. For the price it's just amazing.

hmmmm not that I put much faith in Toms but

Not here to make trouble, but any TIM would transfer the SAME heat for the same CPU (conservation of energy), except for the proviso given above.

However, the bad TIM will have the CPU running hotter.

And while that would seem logical in theory, that's not what happens in real-world practice.

I wouldn't say is "difficult" to spread, but it does require more effort.

damric · Dec 6, 2022

So recently I put a water block on a 6900xt. The grease that came with it was amazing. I just emailed alphacool to see if they sell it or plan on selling it.

These aren't reviews, they're fully sponsored articles that are copy pasted from sites to sites with affiliated links
Everyone who has tried syy 157 has made similar claims to me (as far as ive read)
No pump out in 4 months after a repaste
They claim it's thick and difficult to spread.. i disagree, kryonaut and gelid are harder to me! And theres always the cup of hot water technique if needed

If you want the best of the best.. TFX or these guys https://www.coolsierra.com/collections/thermal-paste/products/ec360-ruby?variant=39723865211020
They also have the best thermal pads with fujipoly.. But SYY 157 remains the best bang for the buck
I suspect it to be rebranded TFX from "less good" batches or normal batches, for fake concurrence.. Common in asian markets!

freeagent · Dec 6, 2022

SYY-157 is no more difficult to spread than Arctic Silver Ceramique II… Maybe they had some dry stuff, not sure. TFX is waaay thicker for sure, that stuff was a tough spread.. but it was cool in here and I didn’t warm it up.

i am highly interested in the SYY 157 paste.
seems to be a very decent paste for direct die applications. anyone here tried it before?

I believe @freeagent has tried some? Or maybe it was gd900... I forget.

That was me, I have gone through about 50 grams already

Its good stuff, use the spatula.. thin not translucent

But that would depend on your cooler I guess, and its mounting pressure...

With all CPU and GPU coolers and also with all GPU and CPU AIOs (with the exception of the Ocean AIO), the Alphacool Subzero thermal paste with 16W/mk is currently always included.

Ok I was wondering because it was in a black unlabeled tube. I'll be ordering more. Thank you!

EddyAlphacool · Dec 7, 2022

@damric
That's correct, we don't have any lables on there. Actually inconvenient as you can see, but in the future there will be lables on it as well, so you can see it right away.
But it has always had the Subzero on it for many years. But next year we will switch to the more powerful Alphacool Apex with 17W/mk for all products (except the Ocean AIOs).

Would Thermal Grizzly Kryonaut be better than the MX-5 I'm using right now?

Edit: I'm open to suggestions as well.

Lol 50g wth lol

A 4g tube usually gets old before I use it all. I have a newish tube (8 months old?) of mx4 2019 Ed (hopefully legit) that I will use on my noctua cooler when I repaste/reinstall.

Considering your MX-5 application is probably recent, I wouldn't bother.

I've got 3 CPUs in rotation, 3 or 4 heatsinks, and a few cases

I do all kind of experimenting

nomdeplume · Dec 7, 2022

How much of that 40g went to disproving the fingertip smear debate we'll never know.

There was a fingertip debate? Do share @nomdeplume.

Yes, just as there was a bendable iPhone debate.

Effectively you just dip a finger into the barrel sized repository your industrial byproduct of note and finger paint it all over the place like you're 3 years old again. Which prompted howls of micro-sized air bubbles and all the usual suspected failure modes being examined in nauseating detail. :laugh:

If it is, it's not by much. Maybe 1 or 2 degrees C

Anyone who considers this, the 20g package, while pricey, is the best value per gram.

For those inclined, there's also an Amazon listing;

There is also AlphaCool's Apex;

This stuff is pricey as well, but it's supposed to be excellent.
