Liquid Cooling Radiator making clicking noise

[joshuaaune0]

I have a Liquid Cooling Radiator that is making a clicking noise, and I can't figure out where it's coming from. Nothing is hitting it, and the only way to get it to stop is to give it a little tap several times. Video: https://photos.app.goo.gl/sSaxp8QTMAW4XrHa6
Any suggestions are greatly appreciated. Thanks

Could it be coming from the pump?

The bearings on the pump wear over time and the impeller shaft can start to wander and this will cause a noise and if you tap it....the shaft will move and ride in the right spot for a while and be quiet until it starts riding in the wrong spot again.

the noise your hearing is a fan making that noise. how long has these fans been installed. ? are they the original fans that came with the radiator ?

If it's a fan....basically the same thing I said above is happening.

An easy way to tell is unplug the fans and the pump one at a time.

humm unplugging the pump will make cpu overheat in like 15 seconds I truly dont recommend it, and since the video clearly shows it is the radiator fan (see top of case) making the noise I really dont see the point of disconnecting the aio pump on the cpu.

Obviously you need to be quick....and I missed the video....so my apologies.

Follow-up:
It was an all in one kit from coolermaster so I'd rather not have to disassemble it.
Also I know it's the one fan because of where the sound is coming from. I could even double check my stopping that one fan with my finger and the noise would probably stop. Still can't see if anything is hitting it 🙁
