[SOLVED] Liquid Cooler Noise

[tlew20]

So I recently got a Corsair H45 liquid cooler, and it's started making a rattling noise which is pretty consistent, sometimes it disappears for a couple seconds or minutes then comes back. Is this normal or is there a fault? Thanks

Did you buy it new?
If so get a hold of cosair tech support sound like faulty pump.

i would check all screws are tight and maybe its just a noisy fan.
check some youtube videos reviewing it and see if they have the same noise problem
