Interesting. But the results seem pretty unbelievable. It supposedly idles 13C lower than AS5 and loads 16C lower. Even commercial diamond thermal paste doesn't perform that well. Most reviews I've seen say that Shin-etsu and other top of the line thermal pastes only perform about 5C better than AS5.
I would think you're still limited by ambient temp and the surface area of the cooler itself... you're not going to drop your CPU lower than your house lol
