Fernando, They were never any quiet ones. There was noisy and less noisy. If you have the orginal Rev.1 MDD G4's, they had the really noisy fans. The Rev.2 had the less noisy ones. Someone else on the list, may be able to provide a link to a site which can show you the difference. I had an original MDD, and it was a beast. Apple did provide an fan upgrade for the original MDD's. Sometimes I see them on sale on Ebay.
