I decided to clean out the case as it had been a while.
The AIO cannot be controlled, SATA power is the only connection on the pump, the only thing that can be controlled are the PWM fans. Exhaust and Intake fans on the case are also different so will need to replace those
The only noise coming from the PC at idle is the AIO pump, and that is causing all of the vibrations and noise.
So I am thinking of something like this (I don't need the case, I just want a new one) - and some form of controller for the RGB
