I have a Radeon HD 6870, and My video card temp when idle sits around 50 to 60 C, and that's with dual monitors and there's no load on the card or anything. Now when I'm only using a single monitor, the temp sits at around 45 C and no load on the card. Why is it that the temp goes up when using dual monitors, are these temps normal and at what temp should I worry about when gaming. Also just recently I noticed a buzzing sound coming from the inside of my case, I thought it was my rear fan but it turned out to be my video card fan. I called XFX and they said it sounds like the ball bearing on the card might be going, so I submit a RMA to them to see if they can replace it or send me a new one. I bought the card in July of 2011. I also tonight took the card out and cleaned all the dust out of it and everything, but it's still making that noise. Any suggestions on what to do if it's out of warranty? like should I just replace the fan/heatsink on the card, or just buy a new one all together? Thanks for all the input.
PS : I also included a video of the problem on what the buzzing noise sounds like when I raise the Fan Percentage.
