Final Thoughts


Thermal Grizzly Kryonaut High-Performance Thermal Paste is available from Overclockers UK for £10.00. That’s for a 5.5g tube, although you can get an 11.1g tube for £15.95. 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 favourite retailers. Prices vary wildly and change frequently.


Thermal Grizzly is going up against some very tough competition. There’s a huge range of thermal pastes on the market to choose from. Gelid GC-Extreme is a popular choice for overclockers around the world, and we here at eTeknix have been using it for years. It’s 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. However, not so much so that I would feel compelled to take my cooler off and change my thermal paste. Although 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. Unfortunately, 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. It could even help with the fan speeds a little in that case.

Time to Invest?

For day to day users, any of these compounds would do the job nicely. Although, 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. And 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.

    Is Thermal Grizzly not meant for delids though?

      TG Conductonaut for IHS-DIE connection
      TG Kryonaut for IHS-heatsink connection

      • Pavel Jelínek says:

        Not true.. You should use conductonaut even between IHS and heatsink but watch for Alu restrictions.. I just saw a video, man delidded his CPU (7700K), used conductonaut, then again between IHS and heatsink and VOILA, guess what – 70°C max!!! And he DID OVERCLOCK TO 4,9Ghz
