I was replacing my PSU since my old one died, but I came across a problem.
The fans will not spin at all now; the CPU fan and case fan.
The PC itself boots up fine, but the fans just do not work.
Any idea to the cause?

if power supply is connected properly, please re-check all connections are secure, then clear CMOS and try it again..

where did you get this spare power supply.?
what is it.?

 

also this unit, what is it again.?
CPU power plugs, motherboard power being 20 or 24, check it all.

The one that I am currently using is the OEM PSU that came with the PSU (20 pin).
I tried a different OEM PSU (24 pin) I had and it still doesn't work.
I actually tried a fan pin to molex connector and the fan worked, but it's at load, which is loud.
I think the pins are messed up :(

The CPU Fan Pin and the Case Fan Pin on the MoBo.

Dead, not working, etc.
The pins are perfectly straight, but the fans will not spin.

Options now:
New MoBo or a fan controller.
I'll go with the fan controller...

If the mobo runs without the cpu fan plugged in, then I agree with a fan controller. My north bridge header went out for no reason and I had to add that fan to my fan control setup. Cheaper than another board.

malmental   02-06-2012 at 01:45:05 AM

fan controller is definitely a cheaper option, yes.
but if the CPU fan isn't working then that's something else..

Monitor just came with an error about the CPU Fan failing.
The strange thing is that it works with a fan-molex connector like this:

works like that but only runs on high I suppose.
this is why I asked about the CPU fan....
you can run on high but will not have sensing control or hardware monitor functions in BIOS.
you can try another heatsink/fan and see if that works but odds are it's motherboard time..

Don't have another heatsink, but I've confirmed it is the MoBo (used different case fans for the connectors; nothing worked).
