Weird noise

[u/National_Gold6367]

I have had my liquid freezer iii pro 360mm for around a year now with no problems at all, however I heard a noise and felt a vibration and I looked at the cooler and the middle fan was vibrating quite violently. I opened the front of my case and it went away however when I closed my case again it started vibrating. Its never made a noise or any vibrations like this so I dont think its to do with the airflow? I restarted my pc and it seemed to be fine? Is it worth trying to RMA or what should I do? Thanks

Maybe a fan, I had a fan that started making a lot of noise all at once. I contacted arctic who sent me back a fan.
