A friend had given me two GeForce 8800 gtx with after market cooling systems and I was going to use them both to take advantage of SLI. When I was looking closer at one of the cards I noticed one of the chips was missing a heatsink. It is the bottom right chip which I believe is a memory chip but I really don't know. My question is will it still be safe to use even if one of the chips does not have a heatsink on it?
