Testing Power to my heatsink

Specs: Windows XP, 2

I'm just building a PC out of scrap parts and I need to test if power is going to my heatsink as the fan is not rotating. The systemboard is straight out of the packet so im 75% sure its not that.

Are there any ways to test if there is power going to the heatink fan apart from plugging it int the board.

Its a propietary motherboard with 5pins on the heatsink instead of 4 that all my other boards have so can not test it that way.

Is there anyway i can rig it directly to the PSU bypassing the motherboard?

Are you benchtesting or did you skip that step & just slap the board in the case without testing it 1st?

If you know which pins to use & have a few jumper wires, all you'd have to do is connect the wires from one of the molex plugs to the fan. The PSU should be disconnected from the board and another jumper wire used between the green wire & any black wire on the main ATX plug...this will allow the PSU to start without being connected to the board/case power switch.

BTW, heatsinks don't require power.

Thx for replying.

Nope no bench testing, The motherboard came out the packet into the case.

OK so making the power supply run using the green and black cables makes perfect sense, done that a few times in the past.

But from the Molex connected to the PSU, to the mini molex of the fan which colour cables do I connect the jumpers(paperclip) to?
