I just bought a Venus12 fan/heatsink for my amd64 system I just built. I was curious if there was a program I could run to control the fan speed. Currently it is running at a constant 5600 RPM keeping my cpu at about 38 C. I think the fan speed is abit high though. It came with a hookup to attach to a bay area that is suppost to control the fan speed if I hook up all the wires, but I am pretty new and my case doesn't even have the right size bay to install the knob at. So is there a program to just do it in the computer itself, rather than manually with a knob?
