I am trying this program and at first set the fan speeds to 3000 RPM as the OP suggested. That resulted in what I consider fairly loud fan noise. So now I'm trying 2000 RPM. It is still audible compared to the near silent default at 1000 RPM. I'm not sure the noise is worth the extra cooling, as a prefer to put my notebook on a table when I use it.

The power supply was another huge challenge. The Supercomputer uses the same amount of electricity as 3000 average sized homes.

How do 1100 dual G5s end up using the same amount of eledtricity of 3000 average sized homes? Even with the cooling and networking, this number seems way too big.
