It's been a while since I sold my Beige G3 266... but I seem to remember hearing its fans revving up sometimes (in really hot days). A technician friend of mine confirmed they had variable speed. So maybe even G3s had some kind of thermal control. > If the fans are suddenly that much more noticeable, they're probably starting > to fail. If the fans have become noisy, that could be a sign of malfunction. OTOH, if they have just become louder, maybe it's a sign of increased temperature (too much dust inside the computer?). -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
