[SOLVED] Fan making loud noise

[luka1000]

Hi I have 2 Corsair Air Series AF120. One of them randomly starts making really loud noises every now and then any ideas on what it could be. I recently got a hole new motherboard and stuff and its still doing it

it may be a faulty fan. check if you didn't connect it backwards somehow. If it's new and connected properly try to RMA it
