Hey all, I recently acquired another G5 ($130!!!) that I'm running as a backup/music streaming/3rd monitor powering system and have run into an odd issue with the fans.
It's a Dual 1.8Ghz G5, 2GB RAM and a 150GB HDD, I believe Rev A. (No one piece CPU Cover, they are independent.)
When in Automatic mode, the fans rev up rather loudly for a few secs when I open new Finder windows, new safari/tenfourfox/camino browser windows or anything that seems to require short bursts of power. This also happens in Highest to a lower degree, and is least noticeable in Reduced (which I keep it on all the time now). On idle (either reduced, highest or automatic), the fans however always seem to be bordering that "rev" stage, where they are rotating pretty fast yet just under that threshold. I can feel the fan force behind CPU1, little less on the bottom one. Even in Reduced, when opening a new tab I can hear the slight revving, though nowhere as bad as in Automatic (sucks to run the G5 @ 1.4Ghz or what it runs when in reduced though)
I've ran Handbrake and used iMovie, as well as intentionally stressing the CPU's at Reduced/Automatic/Highest settings (used the < yes /etc or what it was, did it a few days ago and lost the website) to no avail, the fans never revving up suddenly, only gradually.
The temperature normally hovers around 45-50 Celsius when idling, which is actually very cool compared to my other Power Mac G5 (which hovers at the 55-60 Celsius mark).
I'm using my other Dual 1.8Ghz Rev B as my benchmark, which has worked flawlessly since I bought it 6 months ago. It's fans run normally, never exhibiting the symptoms of the Rev A I have. Even the chirping noise is only confined to file transfers, whereas on the Rev A its more frequent (but thats a non issue).
I've repaired disk permissions and ran the ASD 2.5.7 disk, everything turned up fine as well as resetting the PRAM.
Any suggestions on what I should do next? Any help much appreciated
