Ask ten geeks about their preferred thermal interface material (TIM) and you’ll get six different answers. Five will go with Arctic Silver 5 and the others will have five totally different favorites. Ask a non-geek about their favorite thermal paste and you might get slapped.

We gathered seventeen premium thermal pastes and an overclocked test bed and set about finding out whether thermal paste really makes a difference, and if so, which one is the best.
