Hello guys , im planning on building a new system with a H150i pro cooler and i would like to apply an aftermarket thermal paste .I ve heard that thermal grizzly are good but i dont know which of these 2 options is better.

Kryonaut out performs Hydronaut by about 1° or so. So not a huge difference. However from what I've read on online forums, it's a harder to apply paste than Hydronaut. For the price and supposed ease of use, I'd go with Hydronaut. I've been a fan of Noctua NT-H1, but I just picked up a tube of Hydronaut to test out this week.

Toms did an updated thermal compound roundup last year that's a good read if you want to get in to the details. https://www.tomshardware.com/reviews/thermal-paste-comparison,5108.html

I put Kyronaut under the lid of my CPU and between the heatspreader and CPU cooler. Seems to do the job. Their claims of longevity will be tested there.

For the money you can get a lot more Arctic MX-4, and only sacrifice a little bit of performance on CPUs. Works well on filling in large gaps on direct contact heatpipes. But if you look at the GPU numbers Arctic MX-4 doesn't do so well, but Kyronaut keeps it lead, though I have still used on GPUs.

I actually don't recall what I used on my GTX1080, and it didn't make it into the pictures. Might have been whatever XSPC supplied with the water block.
