When using Windows 98s Power Managment, my harddisk, monitor and CPU fan can be turned off after a while but not the fan of the power supply. Is there a way to turn off the power supplys fan?
Computer Doctor: The power supply fan is wired to run continuously; there is no way to turn it off, unless you custom modify the unit (not recommended) by adding a switch, or perhaps wire up a thermostatic or other type of circuit to control it. If you’re concerned about noise, there are power supplies that are specially designed with extra-quiet fans. Check out the “Silencer” series of supplies at http://www.pcpowercooling.com.
