My PowerMac G5 roars like crazy. I know that this was one of the big issues with it though. Is there anyway to not make it make so much noise?

the PowerMac G5 had been quieter then the Powermac G4 windtunnels
and my PowerMac G5 2.3 dual is not loud at all , on setting automatic most of the time i cant hear him at all apart from a slight wirrrr noise but far from loud , i had louder pc's in the past , after all its a desktop

so which of the fans is the culprit as thats a indication which part has a problem , install istat menu's 2 to watch temperatures and fan speeds


but a general advice if possible never ever let the room temperature rise above 18 degree celsius (64.5 degree Fahrenheit ), the PowerMac g5's are more of the nordic type and thats where hey feels most comfortable :D

My room is pretty cold, other times it's hot. It's just the bad thing about living in Texas. I'll see what I can do though. The machine feels hot on the left, but not on the right.

Because it brought 100MB to 1MB for most videos, it compresses while keeping everything intact.

Believe it or not, you have some fantastically good fans in your G5 already. Compare them to the ones in an ordinary PC, and you'll be shocked. The downside of the G5s is that they're extremely hot chips--some fan use is inescapable. If your main concern is the revving that happens occasionally if your power settings are on "Auto", try "Reduced" or "High Power" instead. You'll either lose some speed or use more power, but either choice will stabilize the sound somewhat. Also, for what it's worth, the single-processor models were somewhat quieter (I've run my single 1.6 side by side with my parents' dual 1.8 to compare).

Your other possibility is the graphics card--probably the loudest and cheapest fan in the computer is the one on your graphics card (unless you have a passively cooled card (FX5200/ATI 9600/9650). The ATI 9800 is the worst for noise in my experience, though the Nvidia 6800 cards also add significant noise even at idle. Can't comment on the ATI X800 series.
