Hey guys, I tried doing a google search for this, but couldn't come up with anything, so I thought I'd ask some more experienced overclockers than myself. I have a sapphire 7970 ghz edition clocked at the stock 1050 mghz, and am trying to create a custom fan curve to make things as quiet as possible. I have monitored my fan speeds while running heaven and determined that anything above 50% is clearly audible, so is it a good idea to downclock my gpu? Thanks all
