i have installed another fan and still no power. fan on power supply is working, this is a w2646 e machine, with a 2.60 intel celeron. there is no boot only the sound of the power supply runing, used pci dig. card and it said to check the cpu.
so could it be the motherboard and has it burnt up the cpu?
but for what ever reason the fan is not getting power.
ThanksReplace that CPU fan immediately if it's not RUNNING...i suggest visiting the MBoard manuf. website to FIND the correct one.To add to Patio's recommendation...also use heat-sink compound as well.

Alan <>< i pluged another fan in and it want work
but the dig, card shows that there is power to the MboardJust because the power supply fan and the VIDEO card fan work doesn't mean the header for the CPU fan should work as well. Could be incorrect / no voltage to the header (the pins where you plug the fan into).

Is the HARD drive spinning up? / Do you hear a 'beep' when the system starts? Do the lights on the keyboard above the NUMERIC keypad light up briefly when starting the computer?

There a couple ways to check it:
1. Put the CPU fan plug onto another header on the motherboard (the fan doesn't have to be strapped onto the CPU as this is a MOMENTARY test just to see if the fan spins up)
2. Check the voltage with a voltohmeter @ the header in question
