Intel RTS2011LC Liquid Cooler Air Problems

[MTD]

Has anyone had any issues with these?
Mine has started clicking like there is air bubbles passing through the pump, Ive gave the radiator a little shake a couple of times and that has normally sorted it out for a few hours, but they eventually come back.

Ive also notice the temps go up by about 8 Celcius if I dont bother clearing the bubbles for a few days.

This is generally how it sounds at best, not sure whether this is the pump itself or air bubbles still passing through the pump.

Sound quality isnt the best so you may need to tur up the volume.
