Wow, had to look up the FX5800 Ultra. What an idiotic cooler design. So nice that the intake is right next to the exhaust.....and a centrifugal fan the size of a dime.
It was a ground-breaking new design at the time. The first floating-point GPU for nVidia. But they had serious problems keeping it cool, and that cooler was LOUD. It sounded like standing next to a jet taking off.
