Default Re: Cavitation or Airleak?

If the noise you hear is from air, you should be able to see the bubbles in the pump "resevoir". Alternatively, your loop could be to restrictive, causing the pump to be fighting the pressure, or suction... or you have a noisey pump.

Try running the pump with inlet and outlet hoses in a loop with just your rad and cpu block to see if it is as noisey. Does your rad have a bleed screw on it? That would help some.
