[SOLVED] Water cooler making craking noises

[Joakin]

I recently bought a processor along side with the water cooling Corsair H100i Pro RGB. And since I installed the cooler I noticed some annoying noises coming from the fans (not sure which one) and they're pretty loud if my rooms totally quiet.
If I put my hand over the fans with no pressure the noise decreases.

EDIT: it’s only one of the fans making the noise.

The cooler works great, it keeps my processor at good temperatures while gaming even though I live in a country with high climate temperatures. However those noises are kinda making me paranoid, I'd like to know if it's defective or not.

Here's a video:

Ok turns out I left a screw in between the radiator and the top of the case lmao. I removed it and the sound went away.

Thank you!
