Hello. I have purchased a H60 hydro cooler a month ago and the pump has this constant buzzing, louder than my 3 fans in the system. I am aware of the fact that it has an operating noise, i just don't know if this buzzing is normal, it quite annoys me. I have tried to move the radiator but it doesn't help. If this noise is normal i'll just accept is, it is my first. With no fans operating, i measure the noise at around 40dB. Here's a video i took:
