[QUOTE="Marrk, post: 1202108, member: 193327"] 1) How many internal cooling fans are there on a PowerBook G4 17" 2) What can I do to diagnose whether or not the fans are working? 3) How hard is it to replace a fan? Where does one get the parts? My 8 year old PowerBook G4 17" is running pretty well, but I am wondering about the internal cooling fan(s). If there is more than one fan, then it sounds like only one fan is coming on. Also, the fan comes on somewhat early, even though this is a machine that has always run very hot. Any thoughts? Is there some kind of diagnostic software that I could download that would tell me if the fans are working? Thanks! [/QUOTE]
