Gang, For a few weeks now, every time I watch a flash movie or visit a flash-intensive website the fans on my 2010 iMac 27 rev up to full speed. They stay at max even after the iMac has cooled down. Is this a known issue? I've googled it a bit but I havent had any luck with a solution. Short of removing flash altogether, do you think there is anything I could try? Putting the iMac to sleep or shutting it down resets the fan, but restarting doesnt. It's weird.
