We can clearly see from the graphs that OCCT 3.0 has drawn that the difference between the 2 thermal compounds is almost a half of a degree, with the same CPU cooler, the Kama Angle. It is nice to see that by using another type of thermal compound, with a better formula, we can get better temperatures, while using the same cooling hardware.
