I have read in Shadowclock's air cooling guide and in many other threads that it is best to put high performance fans like panaflos on a fan controller. Correct me if I am wrong, seems like the recommended fan controllers are all manual. So how do you guys make sure that you are running the fan at the appropriate speed? I am thinking I will feel better if the mobo was increasing and decreasing the speed of the fans based on the temps. But these fans are not safe to put on the mobo header. Is there any good fan controller that automatically sets the fan speed?
Do you guys measure the temps at your most common loads, and set the fan speeds accordingly? And once you settle on some speed do just leave the fan control alone? What if you are not around and the components overheat (Maybe there is some bad software that starts pinning the CPU)?
