I did a search on this subject but couldn't find anything regarding it. I just bought a new processor, it came with a fan and heatsink. I know that i'm supposed to apply some Thermal Paste on the chip before placing the heatsink on it, but i don't have any and i'm not sure if anywhere in my town sells it. But the heatsink that i got with the processor has a gray patch that looks to be the thermal coating that i need, so would i still need to apply thermal paste onto the chip or will that gray patch be enough? Oh my processor is a Intel Pentium 4/ 3.2E GHz 800MHz FSB, 1MB L2 Cache, with Hyper Threading. And my mobo is DFI "LANPARTY PRO875B" i875P Chipset Motherboard for Intel Socket 478 if that helps.
