Apr 14, 2004 50 0 0 My motherboard has plugs for a "PWR_FAN" and a "CHA_FAN" meaning power fan and chassis fan. Well whats the difference? I thought all case fans plugged into the PSU? and btw, none of the fans I have have the right plug to fit those "PWR_FAN" and "CHA_FAN" plugs.

NOt usually. Just means the bios won't monitor the fan speed.

Jan 4, 2001 41,596 19 81 Their labels don't really matter - the only fan header that needs a fan connected (or usually does) is the CPU Fan. A lot of motherboards won't even boot if they don't detect a fan connected to the CPU Fan header. Those others can be used to run 80mm fans and smaller anywhere in the case. 92mm fans and larger should connect to the power supply, as their increased power demands can damage the fan power supply circuitry on the motherboard.
