A couple weeks ago when the ATI Radeon HD 4850 graphics card came out the card proved itself to be a price versus performance winner, but we couldn't ignore the high temperatures that it ran at. Our temperature testing showed that the Radeon HD 4850 ran at 85C at load, which was within specifications, but is too hot for us to ignore. We install a Coolink GFXChilla on a Radeon HD 4850 with the hopes of reducing temperatures and you'll be shocked to see the results!
