I decided I wanted to finally give that Thermal Grizzly kryonaut a try. I guess I had finally bought into all the hype. Been using Arctic MX4 for years with great results. I picked the only size tube they had ant Microcenter which was $11 and was kinda shocked that I killed the tube with one application, the stuff better be good. Well long story I'm not as impressed as I rerally wanted to be. I tested it a couple time with both compands and kryonaut was on average only 1 degree cooler. I thought maybe I had some fty spots. Nope the application and mount of the cpu block was right. Maybe I just got and old tube. At this point maybe if anybody ahas insight as to what went erong maybe I 'l get some more and try again.
