Keeping that high-end graphic card cool and quiet
 

Graphic card manufacturers are more or less caught in a dilemma, their graphic processors generate about the same amount of heat as a desktop processor yet they have to work within the room available between two PCI slots. NVIDIA was actually the first to break the mold and introduce a heatsink on their GeForce FX series cards that occupied two slots. Unfortunately the heatsink was rather loud due to a number of design problems with the axial fan and the casing, but the idea caught on and many manufacturers of aftermarket heatsinks followed suit.
