Someone told me about a firmware update for the new G4 dualies that may help with the fan noise. Was that you Giz? I have looked around, can't find any info at Apple Knowledge Base, do you perhaps (or someone else) have a link you can point me to? TIA<br><br>
You might try a search on MCF- I seem to remember someone complaining about that same thing, and then someone else posting a link to the upgrade...<br><br><br><br>[color:red]Hold on...it's time for a</font color=red><br>
Not sure if this is the same problem your talking about but,<br>MacFixit said that the fan noise is due to a motherboard problem. The only way to fix it is to get a new motherboard or take out the sodering iron. <br><br>http://www.astheappleturns.com has a story about it today too.<br><br>Ryan
I found this info at MCF. But, it seems it only applies to OS 9, which I don't use anymore. Have to look around some more to see if I can find something that relates to this under OS X.<br><br>----<br> This from MacFixit.<br><br>Resetting Firmware on PowerMac G4 Dual Optical reduces fan noise<br><br>Frans van der Geest reports that resetting the Firmware on Apple's recently released Power Mac G4 Dual Optical systems dramatically reduces irregularly loud fan noise when running Mac OS 9. The process for resetting the Firmware is as follows:<br><br>1. Shut your computer down.<br>2. Start up while holding the Option-Command-o-f keys down. You will be prompted to let go of the keys.<br>3. type: reset-all (then hit return). The computer will restart.<br>4. Choose the OS 9.2 Startup disk and restart.<br><br><br><br>
