Re: What is thermal paste?
When I put a few heatsinks on some chips on my mobo, I used thermal paste and a dabb of JB Weld to never loose it's grip (Not reccomending this hehe, though it worked well for me). But I would stick with thermal paste as the thermal paste has it's purpose that you want for transfer of heat, and grease has it's purpse for car engines. :P
