Having just switched from using a laptop back to a desktop machine in the "studio", I'm painfully aware of how much noise all the fans generate. I'm using the stock intel core2duo cooler, cheapo generic psu with an 80mm fan, 120mm case fan and just added a gfx card with yet another fan on it. The base noise level is really distracting when mixing/monitoring (even the noise from the birds outside really pisses me off), so I'm looking at trying to eliminate some of the noise. I'm going to switch to a psu with a 120 or 140mm fan, and buy a 3rd party cooler. I was just wondering if anyone here has had any real success at making a machine less noisy, or upgraded to components with bigger fans and noticed a difference? Anyone using water cooling? Seems quite affordable these days, but all the cheap systems seem to involve using a fan on the radiator, which makes buying a good heatsink for half the price seem more attractive. Any thoughts?
