Recently I bought 2 machines for trading. Both machines are set up for multiple monitor use. The machine that supports 2 monitors is whisper quiet. My other machine sounds like a very loud fan, the kind that you would use to cool a room. I opened it up and found that the loud fan is on the graphocs card. The card is an ATI Radeon 2600XT (x2) 4 monitor card. Does anybody know of any fixes here? Quad cards cost a lot and I would rather repair or live with the sound.
