So I upgraded my pc a few days ago and I bought an i5 6600k, a 212 evo cpu fan to go along with it, a 850w psu and an msi H110m motherboard (since it was quite cheap and had an lga1151 cpu socket). But now, after having installed everything, the 212's fan isn't working, the pc won't turn on, and there's a little light on the motherboard saying there's a problem with the cpu. I don't know what to do, everything else is working ( the gpu is on, the motherboard, etc.)
