Hi all So I have one of these Alphacool pump/res combo units. I have it setup vertically. Over the last few days I've noticed its been leaking where the res tube screws onto the top of the pump housing. It appears that some air has got into my loop and as I game it heats up, expands and this forces the water out, as it onbly happens when I'm gaming. Any thoughts on what I can use to seal it further?
