Ok I've been dealing with this for some time now...I have two VisionTek 5870's in crossfire and running them in eyefinity on 3 22" monitors....It's been great until here recently...Normally when I play Battlefield BC2 I increase my fan speed because the main card will reach 80+C easily during game play and will stay there the whole time...which I know isn't healthy for the card...so I usually put the fan at 60% to 80% which keeps it around 60cish degrees... Well here recently if I increase the fan speed I get some weird artifacts on my screen when just in windows....if I switch windows or anything it's like a flicker at the bottom where the taskbar is. I'm running the most recent CCC version, latest driver and latest bios on the cards. When I turn off the manual control on the fan the flickering stops.....and since it started doing that I don't even try an overclock.....my cards going bad or what?
