I did a lot of research into thermal paste. This was what I settled on for my AIO. Would it have made a difference? I don't know for sure, but I know I've been happy with the performance and use of this product. Is it one of the best pastes? Yes. Is it one of the longer lasting pastes? Yes, from what I can tell. Was it easy to use? Yes. Spread was easy, but you can easily use a line and spread it with heat sink pressure as well. It's thick enough that it can stick if you want it to and can coat a device easily. Is it the absoulte best? Specs say no. but... Is it a great value? Yes. The more expensive stuff has ratings that are barely better than this at 3-5 times the price. At best, that might find you an extra 1-2C when doing some pretty extreme things. I'm a power user, but I'm practical. This stuff is great for my PC, and one day I may repaste my old laptop with this as well. Given I've leaned into undervolting vs Overclocking, this gives me all the performance I need.

After a year or so the paste didn’t dry, not in the tube nor on the cpu. Very happy with thermal grizzly products. It’s second time I bought it and I will buy it again! Very solid!!!

Most definitely works better and lasts longer than generic pastes. Especially in high performance laptops.

It’s got the goo man, helps with the transfer of heat dude. But in all seriousness, Its a decent viscosity but the applicator tips were not the best and caused a bit of buildup

Cool stuff! Literally… I’ve tried a few kinds of thermal paste and as far as I can tell this one has been the most effective. Much better than the junk that came with my CPU cooler. Even the small size has enough to use it at least three times.

9800X3D idles at 35C, incredible. Couldn't ask for better cooling performance for AMD CPUs. Best paste I've used and wasn't that expensive. Relatively easy to apply though a little runnier than some pastes.

This is a very easy thermal interface to work with as it spreads very easily and you don't need much to spread across the entire IHS even on new larger CPUs like Intel's 12th or 13th gen. 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.
