And what of the pump setup? I know reducers are a bit restrictive, so I thought it might be a possible flow issue.
-If the situation has worsen then what you are normally seeing, I suggest that you disassemble the WB to see if the cooling surface is clogged and oriented correctly, look here
-Feel the tubing while the computer is on. Is it room temperature or is it warmer then normal? If it is warmer then normal you may have air pockets. Shake the rad a few times to see if bubbles appear in the loop. Also remove the reservoir's cap to see if there is air pressure there as well.
-I was never fond of the GT. But it's better then the storm and TDX.
-Ambient temps also play a role. Is it warm/hot in the room?
-I would also consider remounting the WB to the C2Q CPU and use the line method when installing the thermal compound.
