Just got my 260 yesterday, and I installed it and got it up and running. Once in a game (AoC, Assassin's Creed are the only two I've tested so far), there is a squealing noise coming from the card. At first, I thought it was a fan, like maybe a wire touching , but it didn't really sound like that. I opened my box and checked everything, all seemed normal. Then, since it sounded electrical, I thought it was maybe my PS, so i kept the case open and loaded a game up, I was rather surprised to to discover it was coming from the card, but it wasnt the fan on the card... Then i started googling and found out about this squealing issue. My question is, what can i do about it? I don't want to void my warranty, I just want it to stop making that annoying sound! Right now I just turn my sound up real loud so that i Can't hear it..
