I have a high-end ATI video card in my work PC that I sometimes play video games on. The fan on the video card is very loud and some days it drives me crazy. I have been considering a passively cooled video card for a while now.
Club 3D has unveiled a new passively cooled video card called the ATI Radeon HD5550 Noiseless Edition. The card uses a massive heat sink and dual heat pipes for cooling. The video card has 512MB of GDDR3 RAM clocked at 800MHz.
