It's possible to run systems which don't use enough power to need fans, but you have to design the system accordingly using either underclocked components or low-power/laptop-oriented CPU and video. Most desktop systems are going to run too hot without some form of active cooling. Also, you probably should start by opening the case and seeing what is making all of the noise: it might be a CPU fan or even a chipset fan, and not the PSU fan, which is causing most of the racket. For the PSU, good vendors include Antec, Foxconn, and Enermax...look for a unit which has a single "smart" (thermally controlled) 120mm fan, as the larger fan can run at a lower speed and still move enough air. -- -Chuck
