Question AIO buzzing

[TheBlazingAio]

I installed a new aio to my pc and when I turned it on, it keeps on making a buzzing sound, it’s not the fans as the fans aren’t making the noise but like the cpu block or the pump, how do I fix it??

how do I fix it?

you may not be able to "fix" it. if it is a pump malfunction, you would just have to RMA the cooler.

if you press on different sections of the CPU block or the radiator, does the noise stop or diminish some?

and are you sure it is not the case or motherboard vibrating due to the cooler's activity?
