Water cooler dripping noise?

[neb1006]

I recently upgraded from a hyper 212 to a coolermaster master liquid 120 CPU watercooler, and ive noticed just recently it sounds kind of like its dripping - ive opened the case up to check and i see no leaks what so ever, my temps are all normal around the 28c mark or lower when idle and around 34c when gaming. I read somewhere that it could just be air bubbles in the pump from the radiator? or could it be something worse?

Run it outside of the case and see if anything drips.

I moved the pump cable from sys fan 4 to sysfan 1, which allows me to control the pump - having the pump run at 100% causes the popping / dripping sound, having it at 50% stops it all together. im 100% sure there is no leak, but im still slightly concerned about the noise.

It might be a bad pump.. But it might just be noisy. Contact the OEM.

Further reference - this is pretty much the noise it makes.
