Which Thermal Paste Should I Use for My AM5 CPU: Thermal Grizzly PhaseSheet PTM or Arctic MX-7?
Asked by

I'm in the process of changing my CPU cooler and I'm wondering which thermal paste would be best for my AMD 7800X3D. I'm using a Thermalright Phantom Spirit 120 SE cooler along with Noctua NF-A12X25 G2 PWM fans, and I want to know whether Thermal Grizzly PhaseSheet PTM or Arctic MX-7 would be the better choice.

Just a tip: PTM works best after going through a few thermal cycles. Overall, most people seem to agree that regular paste is plenty good for your setup.

Honestly, any standard thermal paste from a reputable brand should work just fine here. With your CPU likely staying under 100W on a good day, you don’t need to overthink it too much.

I personally use MX-7 on my AMD 5900X, and it's given me some of the best results. Just a heads up, though – it's a bit thick, which makes applying it a little tricky.

I can’t beat the price-to-performance of MX-7. It’s easy to apply, plus I tinker with builds often. Arctic has been my go-to for a while, and I just realized I need a new tube myself since I'm almost out!

Both options are solid, but I’m a fan of the Thermal Grizzly KryoSheet for CPUs. I think it performs a bit better, plus it doesn’t need to be replaced unless you swap out the cooler.

PasteMaster1: Totally agree! For GPUs, the PhaseSheet is great, but for CPUs, the KryoSheet is definitely the way to go. Although for a chip like yours, regular paste will do the job.
