Temps are great and I see no issues with dry out or degradation in the first few months of use
I would have preferred a spatula for spreading instead of the weird heads that you can put on the tube and spread directly on the die.
This seems to be a good spot for cost to effect as you get greatly diminished returns on Thermal Grizzly's other more specialized options or other premium thermal interface materials that cost more, and you get notably better thermal results than cheaper offerings from other competitors.
I used to use Arctic Silver 5 a long time ago and it was always pretty good but it never really lasted too long before it became a solid and then trying to clean it off always made a mess. Hydronaut always remains paste and even though you'd think thats messier its easier to clean because you know it isn't half solid/half paste.
Arctic Silver always performed pretty well under heat but Hydronaut just takes it to the next level I don't unfortunately have any tests to show you for temps and things like that but I can at least say it dropped my temps 5c on cpu. Not to mention when I repasted my 3080Ti with it it dropped temps significantly (although thermal paste fromnthe factory is almost always designed for longevity not for performance)
Top reviews from other countries
When I decided to go get some new paste, I decided to go with thermal grizzly just due to the amount of respect that has been put onto this product for quality. I was not disappointed purchasing this paste I seen a DRASTIC decrease in temps i'm talking about going from 87-90 degrees down to 78-82 degrees under load. This was during summer months of 21+ degrees C weather.
Highly recommend this paste, I didnt have any weird issues as reported by others with the paste being a strange texture etc, went on easy. I spread it out using the application tip for the tube and had no issues.
