Problem is as follows:
Setup:
Aquastream
Aquatube
Cuplex XT for Athlon X2 3800+
Twinplex pro for 7800GT 512MB (Gainward)
Twinplex pro for chipset
Black Ice Extreme 120mm rad
Tubing PUR black plug & cool
All temps are around 50 to 60degrees, for all cores (proc, gpu, and chipset). I checked several times for leakage and cant find any. I double checked. Been running this setup for over a month, still all works well, so again, no leakage.
But where the hell does the water stay

I mounted the aquatube in front, and the waterlevel goes from full to half in two weeks of intensive gaming. Surely this cant be the meaning.
Anyone got some tips?
