I just picked up a Shuttle SB51G Neon Series refurbished from newegg for $150 shipped (not a bad deal if I do say so myself) and have instantly grown to hate that little psu fan. I am about to order a Panaflo L1A and a Fanmate to take care of the case fan, but the power supply noise still remains a problem. I have thought of 2 solutions so far and would be open to any suggestions or comments. (p.s. im a starvin college student so money is tight, so im trying to fix this as cheaply as possible). 1. Add a second 40mm fan to the psu and try and reduce both of their speed to try and copy the Shuttle Silent X power supply. 2. Mod my psu to be fanless. I have 3 large heatsinks laying around from such things as a radeon 9700pro, a P4, and an old PII. I was thinking I could hack them up and have some big headsinks sticking out of the back of the case or possibly make the whole psu external to improve the passive cooling. My only question about this one is, can it be done safely and reliably? I don't want to burn my apartment down. Thanks!
