I am having problems getting this cuplex XT properly mounted on my Asus P5B-Deluxe Wifi mobo on a Core2 Duo 6600 cpu...I am getting idle temps in low 40's, and load is low to mid 50's when the temps outside are around pretty cold in the winter time.

I already bled the system of air bubbles, and I have a T-Line setup to trap the air.

Currently I have my system going Aquatube->Pump->Rad->CPU(Cuplex XT)->GPU(Aquagfx 7950)->res(aquatube).

As my GPU temps are around low 40's (used to be high 60's), I think that my CPU waterblock is not sitting flush with the CPU.

I have tried re-seating it many times, re-applying AS5 and mounting w/o the springs. I am using 6x1 tubing with the AC fittings, and only wcing the CPU and GPU..
