Discussion AIO pump loud buzzing/humming

[Wooderzon]

I just built a new PC and the AIO I’m using is a 280mm Corsair H115i ICUE Link. For the first few days, it was silent, now it makes this annoying buzzing sound that doesn’t go away. My radiator is mounted to the top of my case so it shouldn’t be an air bubble, but just to be safe I’ve already applied the solutions I found to rule that out. Idk if this video will quite do it justice but this pump is very audible and I can even hear it while gaming if I focus on it. Currently I’m going to ignore the sound but if anyone knows something I can try to alleviate it that would be great. Also, lowering my pump speed doesn’t seem to help other than slightly altering the pitch but the buzzing remains. Is this normal? I may be overthinking it slightly, but the sound drives me crazy. My last AIO (also H115i but older model) for 5 years was essentially always silent. Thankfully my CPU temps are fine with a 9800X3D so it’s doing its job there.

Then it is a bad bearing inside the pump.

Either use it until bearing gives out or return AIO and go with air cooling instead.

Since with air cooling, only thing that can go bad, is fan on it. And replacing 120/140mm fan is both cheap and easy. Compared to AIO, where you have to replace the entire thing.

Except for fan(s) there are other things that can wear out or go wrong o get damaged. Vapor chamber(if it as one) and heat transfer tubes contain fast evaporating liquid that deteriorates an changes chemical structure with time and heat pipes are coated inside with fragile spongy compound that can be detached from metal and stop doing their job. That can take some time but they are easily damaged by rough handling or vibrations. So no, they don't last forever, only the ones without tubes.
