Just a heads up in the right forum - a week ago Thermal Grizzly admitted they had a bad batch early in 2018 - Kryonaut abrasive?? , not ground good enough, with large particles left in the paste leading to scratches on heat transfer surfaces. I bought mine in March 2019 from Amazon seller "Onyx PC" (the only one that had Prime) and my laptop CPU die and heatplate look pretty bad. Thermal Grizzly doesn't record serial numbers, is unable to recall the product, so you may or may not get a tainted syringe even when buying right now. I wouldn't probably notice if my idle temps didn't go 20C up after three weeks following the repaste, I blamed it on the paste degradation over 80C, based on their product page saying that "Kryonaut uses a special structure, which halts the drying out process at temperatures of up to 80° Celsius." - and my 6 core GS65 with power limits removed was hanging for extended periods of time near 95C. Right now I'm not so sure, maybe they messed up more than just zinc oxide powder particle size. Even bone dry it shouldn't kick the temps from 30 to 50C under the same package power, and when I removed it it wasn't even dry at all, looked normal. But - the GPU on the same motherboard was fine (other than scratched), and since the GPU didn't really go above 70C I still think the temperature has something to do with the Kryonaut degradation. If you're planning to use Kryonaut test it first on some throwaway surfaces and see if it gets scratched. And keep an eye on temperatures, see if they don't degrade if you're pushing the machine hard.
