Thermal Grizzly Thermal Paste Vs 6 Major Brands Review

Final Thoughts


Thermal Grizzly Kryonaut High Performance Thermal Paste is available from Overclockers UK for £10.00 for a 5.5g tube or £15.95 for an 11.1g tube. That is quite expensive, but it’s about on par with other high-end thermal pastes. As for the other products we tested, I would suggest you search your favorite retailers, as prices vary wildly and change frequently.


Thermal Grizzly is going up against some very tough competition, as there are a huge range of thermal pastes on the market to choose from and some of them have been proven and established for many years. Gelid GC Extreme is a popular choice for overclockers around the world, and we here at eTeknix have been using it for years in all our cooling tests, on our test benches and even in our own personal systems. I am happy to say that Grizzly is just that little bit better than GC Extreme, not so much so that I would feel compelled to take my cooler off and change my thermal paste, but close enough that you would find it’s a good alternative to GC Extreme.

I had done testing on the acoustic differences with these thermal pastes, but there was no difference in fan speed due to the temperatures. However, this may not be true for your cooler or fan profiles. If your fan kicks up a few more RPM at (for example) 60c and your CPU runs at 62c while using cheaper thermal paste, then upgrading to something like Thermal Grizzly could help you cut down the temperatures and the fan speeds a little.

For day to day users, any of these compounds would do the job nicely, but when you’re getting into the world of overclocking, benchmarking and water cooling, then you’ll want to invest in something suitable. Spending hundred on a CPU, motherboard, GPU, water cooling and more isn’t exactly cheap, but spending £10-15 on a good thermal paste isn’t going to increase your budget by a significant percentage and will have real-world benefits in the long run.


  • Better than GC Extreme (if only a by a little)
  • Changeable applicator nozzle on tube
  • Competitively priced


  • Retail availability isn’t great at the moment, but it is improving

“Thermal Grizzly may be the new kid on the block, but they’ve certainly got a product that can proudly go head to head with many of the best thermal pastes on the market.
