Galahad users - anyone else experiencing whine?

[mikehhhhhhh]

I always thought it was my fans, until I was working in the machine one day and noticed it was definitely coming from the pump.

A high pitched whine. Not too loud, but a pitch that just pierces your skull!

I managed to improve it by reducing pump RPM from 3000 to 1900 but it still returns intermittently. I also get the odd intermittent water/gargling noise.

The rad is positioned above the pump, so I don't think it's anything to do with that.

Is there anything I can do or is it an RMA job?

I fitted a Lian Li Galahad aio for a friend and didn't experience any issues like that. I guess it's possible you might have some air trapped in the pump that you might be able to free by giving the computer a gentle rocking?
