If I buy a 1600 rpm fan to put on my sink will the BIOS control the speed so it's not always running at 1600 rpm? I'd like to have the extra breeze when need but I'd like it to be quiet otherwise.
Most mobos control the CPU Fan, newer ones add PWM control to the old voltage control. Settings are available on the Health page of the BIOS setup and thru the Health Monitor utility that comes with most mobos and sometimes 3rd party Health Monitor programs.
