Intel HSF broken or motherboard problem?

[Jakeybob]

Third problem now with my PC >.< The heat sink fan for my CPU isn't running, I've tried re-seating it a few times, checked the pins were all the way in but still nothing. Is there any way to tell if it's a problem with the heatsink of the motherboard?

TRY ANOTHER HEATSINK NO OTHER OPTIONS I GUESS

I could buy another to try but if it is the motherboard then the fan will be kind of wasted... Any way to test which it is?
