Do I need to add thermal compound?
I am about to perform an installation of a new logic board in my machine, and when I pulled the old one out, I noticed thermal compound was on the heat sink under the ATI Graphics module, as well as under the processor. I bought a used board off eBay and it there is compound on the processor and graphics module in the photo on the advert, however, there is absolutely no mention of this on the iFixit guide? The guide only mentions adding thermal compound to the heat sink where the processor is.
Is this a good question?
