I have an occasional problem similar to those mentioned above. My G52 2.3 GHz Dual Processor (early 2003 if I remember correctly) fan speeds sometimes make no sense at all.
The ambient temperature is generally at around 70 degrees F. or a degree or two cooler in the winter (as now). I can be browsing the web, moving local files around, building C code, etc., and the fans generally run at a pretty low speed. Now and then, though,--sometimes when the system is just idling along--the fan speeds increase dramatically. Sometimes the system even *hangs up*, with the fans running at full speed, and I have to hit the power button. This does not happen often but it sure bugs me when it does. What happens if I leave my machine running while I'm away from home, and the fans go to full speed for several days? Do the fans bur out? Would the system overheat? Who knows? So I just never leave the system fully up when I'm away. (I leave it in Sleep mode so that the fans don't run at all.) -- 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.
