The Official Thermal Interface Material thread

I am probably just talking shit to be honest. But so far I have not seen any pumpage on my CPUs.

Hi,
With that big air cooler I find it difficult to believe you could see any lol
 
I use the spatula with these AMD's

If I take my time works really well :D
 
is it possible to use Thermalright Tfx also on VRMs and VRAMs? since the heatsink of the above also expands by thermal expansion and if the thermal pad does not compress enough it could slightly flex the heatsink and reduce contact on the CPU and GPU.

MX 4 is one of the best ofc, but keep in mind that there are differernt batches too, and one tube wont necesarily contain the exact same paste as the other. The main issue with thermal grease in general (tried Arctic silver 5, MX4, MX2, Deepcool Z3 Z5 and Z9, also that Noctua thingie that came with the cpu cooler) - is that for power hungry graphics cards (especially HD 7970 GE, i owned that graphic for about 4 years, from 2014 to 18) the thermal compound degrades in only 1-2 months ! After that time you can fire up furmark and clearly see a really bad temp graph, and after repaste it comes back to normal. Didnt happen with GTX 1060 6g, but happened again with 580 8g. Switching to liquid metal made a huge difference.

For cpu (non delidded) it doesnt have that issue, but keep in mind you can install cpu cooler without thermal paste and it will still work fine. i sometimes build a test bench with i5 3470 and i just slap an athlon xp era heatsink onto it and a 120mm fan on top, (no thermal grease) and it doesnt go beyond 70c in prime95.
 
For what it's worth, TG Carbonaut works really well and doesn't degrade at all, using it on my laptop CPU and GPU and the temps have maintained after 1 year and 7 months. At the one year mark I was bored and curious and changed to TG Kryonaut (the carbonaut pad I kept of course as it is reusable), the temps on Kryonaut was a good 3-4 degrees cooler but after a few weeks started to degrade and performed worse than the Carbonaut. To be fair my laptop heatsink have lousy mount pressure with the triangle 3 screw set up (inherent laptop heatsink design flaw in most models) so any sort of paste won't work too well after some time.

Still using regular paste on my desktop as it has good mounting pressure and good temps (CM Hyper 212 EVO), also not economical to use Carbonaut on desktop (actually for my case it could be as I rarely take it apart, but another carbonaut pad for Intel 35mm costs about 20USD where I'm at and I have a 30G tube of good paste on hand so it was a no brainer.

Conclusion, carbonaut works very well for systems with not too great mounting pressure or an uneven heatsink as the thickness helps bridge the gaps. It won't beat fresh applied paste like the Kryonaut or the equivalent but what it does best is stability and longetivity. I literally do not need to repaste my laptop ever now, just open up to clean fans and dust. It's also not suitable for overclocked systems (duh).
 
Went back to MX-4 myself, I didn't like MX-5 as much. This time I got a 8g syringe so it lasts longer.
 
Need to re buy some thermal paste, it's kryonaut still the best in class, or any other has more efficient?

conductonaut;) its the best tim, but 1) needs to be correctly applied 2) a bit more expensive. But for a crucial component such as 200W+ graphics card or overclocked cpu it would be the best investment, totally worth it

Aluminum heatsink?

For aio cooper I think and gpu

I will avoid liquid metal since I don't have any experience with it

then any tim would suffice, aluminum would be the bottleneck here (and not sure if any cpu/gpu part that is 60W+ has got all-aluminum base).

I have an Intel Core 2 Quad Q9550 running fine on just aluminum (TDP 95W)
 
Hi, I wonder, as I ordered both

Iceberg Thermal FUZEIce Plus & SYY157

Both will arrive from USA in 1-2 weeks, I am thinking, maybe certain die will benefit more from either one of these? or both GPU and CPU go with SYY157?

Reminder it is ASUS G513QY, Ryzen 5900HX and RX6800M.

P.S. REplacing from Gelid GC Extreme....

As time left till pastes arrival, still doing some thinking :)

Thank you so much!
 
I'm about to order some stuff from a local shop, so I thought I'd also get some spare thermal paste - and use it as an excuse to get rid of the sticky MX-5. I'm just wondering which one I should try this time:
  • Arctic MX-4: my usual go-to solution, much better than the MX-5,
  • CoolerMaster MasterGel Maker: I've tried this before, it's an equally good paste,
  • be quiet! DC-1: I have a be quiet! cooler (in my profile), and I'm wondering if paste from the same maker would make a difference,
  • Thermal Grizzly Hydronaut: YouTube is full of Thermal Grizzly ads, so it's either really good, or they just want to boost crappy sales by sponsorship ads. I don't know.
Thermal conductivity is important, as I'm running my Core i7-11700 with a 200 W power limit (essentially unlocked), but as the MX-5 made me realize, ease of application is even more important than that.

What do you guys think?

What's The BEST Thermal Paste in 2019....? (Ft. GD900) - Bing video

Hmm... the reviews I've found don't seem to be too fond of it. :confused:

Another contender is the Thermal Grizzly Kryonaut. It appears the be the best paste on the market, though a bit expensive.

Also a random question: Thermal Grizzly has a line on their product page: "Do not use in silicone sensitive applications." What does that mean?

NT-H2 and Mastergel Pro V2 are almost identical in performance and are basically the best non electrically conductive pastes you can get imo.

The Mastergel dropped my gpu temp by 5 degrees compared to stock paste.

Much appreciated; now that's confusing.

Anyone else on TechPowerUp using GD900?

My attachment above failed, so I try again
