Question Losing my mind over AIO noise

[mrsoup1]

My AIO pump is making a constant whirring noise. At times it's better and others worse. It's either a continuous whirring or like the sound of a HDD writing, at its best. It's NOT the internal fan, I've tested it by turning the fan off. I've tried turning my case which sometimes causes a sloshing sound and that improves it (at least for a while). My temps are absolutely fine (25-35 degrees celsius). It's a front mounted Asus ROG Ryuijin II.

And : "I've tried turning my case which sometimes causes a sloshing sound" - how are you turning the case and what orientations do you hear (or not hear) the whirring and sloshing?
