As noted the purpose of TIM is to aid heat transfer but many folks think more is better and this is incorrect.

The secret to good results with any TIM is to use the thinnest layer possible as TIM is only intended to fill the MICRO PORES in the heatsink and CPU heat spreader which are machining marks, scratches and minute low spots. More TIM is bad as TIM is an insulator compared to metal-to-metal contact. You only need a translucent film on the CPU. A film .003" or less in thickness is plenty. Most people use 10+ times the amount of TIM that should be used.

Numerous TIM tests show the top ~25+ TIMs produce the same temps. within 1-2C so pick whatever makes you happy.
