Dual Powermac G4 1 Ghz ... NOISY!

[BillGates]

Its noisy but its really fast. I've got striped Ultra 160 drives along with the original drive in my dual 1000Mhz. The additional Radion card and 1.5GB of RAM add even more heat. I'm glad its got cooling capacity.

Adding a voltage regulator to the fan circuit could interfere with this circuitry and cause damage. It will also void the warranty should damage occur. My GHzDP is running quietly for me and I am used to having a Cube on my desk (yes I still have the Cube).

U learn somehting new everyday. Is this intelligent fan thing software controlled?

Heh... and if these dualies get that much fan imagine how much that rumored/fake QUAD would get... I can just picture the quicksilver case with a swamp cooler hanging on the side.

I'd wager that most of the noise is coming from the Ultra 160 drives. I found that to be the case when I was using my two 18GB Seagate Cheetah's (10,000 rpm, Ultra 2 Wide interface). When I pulled them out of my G4 tower, the noise went down a lot.
