I think you meant the other way around, normal fans use ball bearings. Many new quiet fan designs use fluid bearings, the idea being the same as in quiet hard drives like Seagate's Barracuda IV (and V, I think) models. > I read and have tested that 120mm fans are much quieter than the regular > 80mm fans. I've heard the same. Larger size means you can move the same volume of air at a lower RPM, thus lower windspeed over the fins, grills, etc. I've found http://www.silentpcreview.com/ to be a helpful site for quieter PCs, whether one is looking for readymade quiet components or making custom mods. > PCs.

SilentPCReview and other sites give pretty good coverage to the tradeoffs, but the bottom line is yes, you can have fairly quiet PCs these days. -jrm -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/ TriLUG PGP Keyring : http://trilug.org/~chrish/trilug.asc
