I just installed my Aquagate Mini R80. I have a microATX board and small case which had a 120mm exhuast fan, but not enough clearance for the Mini R120 so I installed the R80 with a fan adapter to fit the 120mm mounting holes. It works fine. It runs about 10 degrees cooler than stock which is awesome, but there is an annoying ticking sound coming from the water block (the part on the cpu). When I first installed it I did not hear it. Then after the first couple of reboots it started and has not stopped. It is still quieter than the stock cooler, but it is noticable even from 20ft away. Is this normal or is the pump going bad or already bad?
