Finally got the pump back, not very impressed with the turnaround time (look at the date of my previous post...)
Anyway it's working ok but the way I have set it up now I can't get all air out of the system
The water goes from the Pump, straight up to the rad then down to the CPU>GPU>Chipset and then back up to the HDD cooler and finally back into the tank ontop of the pump...
I know I have air in the system because the pump makes a very annoying noise...
