So i have bought some Corsair LL120 rgb fans, which i thought would work well with my build. However when i connected the first one, it worked for a second and then sounded like it was getting electrocuted or something. The light then disappeared, and it has now seized to work. I want to find out what the malfunction with my pc was, before i try installing another. I have an ASUS ROG STRIX Z270H Gaming motherboard, A gtx 980 ti and an i7-7700k.
