Noticed when the rpm is set between 800-1000rpm that I get like a vibration rattle noise. Been stopping the fans and checking the vrm fan, making sure that a wire isn’t vibrating on the back of the case however it’s non of them issues which makes me think it’s a trait of the pump? It’s not a constant rattle it’s more of an intermittent pulsing.

does anyone else’s do this as when setting it at a speed below 1000rpm. above 1100rpm there is no noise.

everything is hooked up right to the CPU header as is intended due to the configuration of the AIO

I had a similar issue with Cooler master AIO a few years ago. The problem was, there was not enough coolant because of the leak I had. Very tiny leak from the cooling plate. When the pump was set to max RPM there was no issue, but when it was sitting at 50% give or take - rattling.
So check for leaks. And another reason - just the pump is gone bad.

Pump speed doesn't change in that model, it's always at max speed, only fan speed is adjustable.
