Thermal Compound for PCs?

[blueb8llz]

i use that between my 7xl and heatsink. i have not tried running it without the compound so i cant compare temps. but even with the compound, you still need to take breaks inbetween because the motor still runs pretty hot. the motor temp was around 186 after 15 mins of bashing. and it was like 60 degrees outside, and i have holes cut out on my body.
