So i bought an Antec Kühler H2O 620 for my birthday. It is my first water cooler, so i'm pretty excited about how it is gonna preform 
I reversed the airflow in my case, so the air will be forced into the case at the back through the radiator. the 140mm fan at the side of the case is supposed to cool air and the other components down a bit, and finally the front fan will force the warm air out of the case.
while playing bf3 the CPU is at a steady 30-32C, GPU is arround 55-57C. The idle temp of the whole system is arround 30-40C.
