New G913 - AIO Cooler seems to be making 2 annoying noises.

Hello - picked up a G913 last week and yesterday noticed that a sort of periodic humming noise was coming from the case. The top of the case (where the AIO fans are) has a definite vibration in sync with the noise. After opening it up (which did not reduce the noise at all) and using my ears, I determined it was indeed coming from the AIO fans. Can't quite make out which one. I made sure the fan mounting screws on the top of the case were tight but did not dismount it or anything like that. I pressed on various parts of the fans and that's when I discovered the second noise…

I also checked to see if the screws attaching the AIO to the CPU were tight, and they were. I happened to gently press on the center of the pump and immediately noticed the absence of a constant, very high-pitched whine. I hadn't noticed it because I was focused on the lower-pitched and louder humming.

So, it's making 2 noises:
1) a periodic, loud humming
2) a constant, slightly quieter high pitched whine.

Of the 2, the 1st is really annoying and I don't think I can live with it. It appears to be resonance-based due to the case vibration, but it's not internal-case air-pressure related because it still occurs with the case off.

Any troubleshooting steps I can take without voiding any warranties? Or should I just bring the PC in for service?

Thanks in advance, and Happy Friday!

So long as you don't damage the system, the warranty is valid. Do you have the Lian Li or Cooler Master AIO?

Just to clarify, the main issue is that the AIO cover vibrates and creates the high pitched whine, correct?

The low humming you described is purely from the AIO fans?

Yes the fans are producing a periodic humming - it's quite loud as I sit here typing. It seems resonance-related as it seems to appear and disappear at certain fan speeds.

Edited to add - the main issue is from the fans. the AIO pump cover whine is a secondary concern.
