I have a dell gx280 full-size tower that requires a 5-pin fan connector for the CPU fan. I cannot find a pinout anywhere and do not wish to fry my mobo hooking up something incorrectly. I know that only 4 of the 5 wires are used, one is for speed control feedback and one is thermal sensor. Could someone pleaase help me find the pinout? It's not available thru dell website anywhere I can find, and no forums anywhere I've searched (for days) have this info.
