I built this computer in November, and nothing was wrong with it, however recently the fans have started disconnecting on and off, especially for my CPU. As of now the CPU fan is doing alright but the stock fans for the chasis and the back are off. Is there something wrong with my motherboard? I've tried using different plugs for the two non working fans, but nothing, they only spin on the initial start up. I'm not too sure whats wrong with it. I can provide more info when asked.

Motherboard: Asus Pro Gaming Z170
CPU : i7-6700k
CPU Cooler: Corsair H100i v2
