Hi all, I am new in the water cooling world. I have read people saying water pumps are noisy and others say are inaudible. In charts they are very quiet, with idle noise under 10db.... I have the Corsair H115i PRO RGB, and with the fans off, the pump makes around 30db noise(IDLE). The sound is not coming from air in the sistem(there was air the first time). I had a ML240L and it had the same pump noise level... Please see below charts and a video showing the sound of my setup....

All connections are right and MO is an Asrock 570itx, everything is well placed as well. I changed modes on the BIOS to PUMP and DC/PWM but it keeps the same noise.

If that noise is the normal level, I will have to get back to Air cooling.

Thanks for your help!

How do you have it mounted in the PC? You may have air trapped in the pump again - these units are not topped off with liquid.

That video doesn't help too much. Positioned like that will trap air in the tubing, going back and forth between the pump and the radiator.

If the radiator is front mounted, you want the tubing at the bottom, so the air gets pushed through to the rad and gets stuck at the opposite end.
Top mounted rads don't matter as much.

You didn't pull the unit out of the packaging pump-first, did you?
