Best long term thermal paste?

Hi I was just wondering what you think the best long term good thermal paste is. L

 

Would thermal grizzly Kryonaut be an option? I heard it dries up and cures in a few months if it is at 80+ C constantly. Is that right?

probably any thermal past will do. but maybe. can re do it say a year or so for a few degrees better.

Hi, I am thinking of getting the Kryonaut paste from thermal grizzly but I just have a few questions.

 

Is it really as good as they say? I'm hoping to repaste my 5800x because it reaches 90C in Cinebench R23 multicore.

 

Is this thermal paste good for long term (12-18 months per repaste)? I had read that at 80C+ it would degrade down in a few months, is that true?

 

Would a 1 gram tube be enough to spread on R7 5800x IHS once?

 

Thank you for the help!

yes. but get the one rated for your cpu.

Could you please elaborate by what you mean by "rated for your cpu"?

Kryonaut consistently preforms near the top of thermal paste rankings, but it can be pretty expensive and hard to find, depending on your location. What cooler are you using on the 5800X? The difference between Kryonaut and something much cheaper and more widely available (like Noctua's NT-H1 paste) is less than 3 degrees C. 

 

As for Kryonaut's long-term performance, it seems pretty consistent with other high-end thermal pastes (1-2 years between re-pastes). There was a bad batch last year that caused scratches on people's coolers, but that seems to be cleared up now. Just make sure to buy your paste from a reputable seller. 

My System: 

AMD Ryzen 5 3600XT • Noctua NH-D15 • MSI MAG B550 Tomahawk • 2x8GB G.skill Trident Z Neo 3600MHz CL16 • MSI VENTUS 3X GeForce RTX 3070 OC •  Samsung 970 Evo 1TB • Samsung 860 Evo 1TB • Cosair iCUE 465X RGB • Corsair RMx 750W (White) • ASUS VG27AQ • Logitech G810 Orion Spectrum • Logitech G502 Hero

 

Got any questions about my system or peripherals? Feel free to tag me (@bellabichon) and I'll be happy to give you my two cents.

I'm unsure what exactly you mean by this. Processor manufacturers don't typically give lists of compatible thermal pastes.

My cooler is the h150i elite capellix 360mm aio.

 

Would this be a reputable seller?

EDIT: Chances are I would recieve a new unproblematic batch from that seller right? As it has been over a year since the problem.

It's enough for multiple applications

 

Fresh paste probably will not reduce your temperatures more than a couple degrees, what paste are you using now?

90 Celsius with a cooler like that, you might want to make sure your airflow is good and your cooler is mounted correctly. Good paste won't do anything if those are your problems.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

Draws 400 watts under max load, for reference.

I am using the pre-applied paste from the h150i elite capellix. The problem is that I touched (lightly pressed on it) the paste accidently with my finger before installing the pump head. Could that be why it reaches 90C in Cinebench R23?

As someone who has redone the thermal paste several times on my desktop. Usually about 1 year apart, it makes almost no difference. From my loose observations it may drop the temp by 1 degree at most and may make the CPU cool off faster a gaming session. However, other than that there is no difference. I do use Thermal Grizzly Kryonaut.

 

My CPU never gets above 77 degrees, so I can't comment on the drying out thing.
