Gurgling noise from sealed loop cooler

post #1 of 5
Thread Starter 
When I first turn on my PC the liquid CPU cooler makes a bizarre gurgling noise for a few seconds which quiets down as the system boots up. I know it means there's air bubbles in the system but this is a sealed-unit cooler, so is this something to worry about?

How is your radiator mounted? It should be above the blocks height at all times, this way it acts as a kind of reservoir so all air floats to the top of the rad and not back into the system

EDIT - Also the pipes that carry the fluid should be going in downwards. Have you got it mounted on the rear or on top?

It's because of pump power setting controlled by your MB. When you first turn on your computer, pump runs at 100% with quite a noise. Then your PWM profile for the pump is loaded to make the pump run at lesser RPM. So it is totally normal I think.

It's mounted on the rear panel inside the case, where the 120mm rear exhaust fan would go. The tubes circle around and connect to the bottom of the CPU block. I can take a pic in the morning.

I mean as in... Are the tubes that lead into the rad on the bottom or top, they should be on the bottom for better flow and for the system to remove air
