I would say my CPU is high due to thermal paste. I get 38-35-37-36 when idle. As for the rads here they are: http://www.watercoolinguk.co.uk/p/XSPC-RS360-Radiator-Black-_42.html http://www.watercoolinguk.co.uk/p/XSPC-RS240-Radiator-Black-_67.html I think I am going to drain the system, check the GPU block, lap the CPU and make sure both have the correct thermal paste. If I get high temps again then I give up and I will run the system with high temps. I cant spend any more money on this PC for a 2nd loop which is why I didn't have one in the first place. Thanks for all your help.
