I would suggest checking the web. Search for "G4 Quicksilver noise" or put "fan" in there. There used to be a website devoted to the Quicksilver noise problem. Apple released some firmware trying to improve the issue so you could check their website as well http://www.apple.com/support There are many how-to's on various web sites that detail how people reduced the noise. These how-to's will show up doing the search above. xlr8yourmac.com is one that will show up. -- Timothy Pitts tpitts at mac.com On 12/11/03 10:30 PM, "LeftyZ at aol.com" <LeftyZ at aol.com> wrote: > I'm new. > > Can I check the previous emails sent to this list?
