looking for recommendations on creating a loop for just my gpus. I've got 2 5870s that id like to water cool in a Panzerbox case that allows for a 120.2 setup to be mounted inside the case. Im not concerned about the processor as I have a corsair H50 keeping it under control. My objective is to silence the fan noise while keeping the gpus as cool at a minium as the stock cooler does...although im sure most any aftermarket cooler can accomplish that. Thanks for any info guys.
