Re: Fan issue on Powermac g3 400mh, 640 ram
Thank you to all! That makes me feel a lot better. I guess I'll just try to monitor in case of a fan failure. I really like this old Mac. It always makes me smile when I open the case and see the amazing interior. Giving it to my elderly parents and will try to teach them how to do email. I have set up a very simplified desktop for them with only a mail client (Thunderbird), iPhoto and Safari.

Re: Fan issue on Powermac g3 400mh, 640 ram
I have 3 BW G3s and neither fan ever stops spinning while they're powered up. I was under the impression that they weren't supposed to stop On Apr 24, 10:06 pm, crumvoc crumvoc...@gmail.com wrote: This computer works great, except for other than a power-off, BOTH the fans (internal and power supply) will not shut down.

This old computer doesn't support hibernate (safe sleep), which would be the only situation I'm aware of where an operational desktop would have the fans stop running while not in a shutdown (power off) mode. Both fans SHOULD be running in any mode other than a shutdown. If either stops, that's when you've got real problems. -- 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.

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.
