Hello Olin, > Some newer systems have speed controlled fans based on > temperature. Messing with the fans on those systems is a very bad idea. > Why do you want to reduce the fan speed? It won't save much power. Is > noise the issue? I think noise is the main issue. I hate all the noise my PC makes and I've put some small resistors (33R IIRC) in series with the fans to reduce the noise a bit.
