Thermal Grizzly Kryosheet Mini Review

The thought of being able to use a graphene thermal pad in place of prone-to-drying-out-over-time traditional thermal paste in a Mini-ITX server I want to be able throw into a closet and not ever have to think about is a pretty compelling one. And since I was going to the trouble of it, might as well do an apples-to-apples comparison to see if there are any performance penalties from making that decision.

Here’s an extremely quick comparison between Kryosheet versus a fresh application of a decent thermal paste, Arctic Cooling’s MX-6. The CPU for this experiment is an AMD Ryzen 7 Pro 5750ge which is being cooled by a Noctua NH-L9x65.

Metric MX-6 Kryosheet
Idle temp (C) 33 34.8
sysbench cpu --threads=16 (ops/sec) 41,620 41,821
Temp, 10m stress test (C) 50 48.9
All-core speed, 10m stress (MHz) 3,518 3,518
Cost (per application) ~$1.25 $23

Apart from the staggering difference in per-application cost, I think this is a pretty good argument for switching to Kryosheet in low-wattage, long-term builds. And to think doubters speculated that carbon nanotubes would only be a novelty in the lab and wouldn’t ever find a real-world use!
