Trying to test 120mm fan on a CPU heat sink

hey, sorry if this is not the correct section.

So i am selling an old heat sink that i have, i just took it out and installed my new one, but i thought the fan was rattling or something in the old one, so i decided to just plug the fan back into the board and get close and see if i can see anything rubbing etc. but its weird.

The fan does not spin at all, the LEDs light up however, now im 90% sure that its working, (at least it was before taking it out)
If it matters its a cooler master V8 and it uses 1x 4pin power connector.
and my NEW cooler uses 2x 3 pin connectors.

Basically i just want to know how i can test my old cooler's fan so that i can put an accurate description when selling it.
Thanks

  1. open the pc and plug the 3 pin conectors into the system fan header one by one or you can get a molex to 3 pin and feed it the full 12v, but either way, if it spins its working and if it doesnt, its not

    i plugged it directly into the board into a 4 pin fan connector, and it didn't spin
  3. try plugging it into a 3 pin connector, then try another board, sux dued, always considered the v8 the sexiest cooler hands down
