Hi there, I've recently been looking at watercooling my newish pc. I have an i5 2500k which I would watercool and overclock to ~4.5 - 5 GHz initially and then add a GPU into the loop when I upgrade it. My case is the corsair carbide 400r, which has 240mm rad mounts, but with some careful measuring I can see won't fit full size (60mm) rads in without interfering with the mobo. I have been thinking about getting full size 120mm rads and mounting them in the back of the case or on the back of the hdd cages (one on both, or one on either for now). My question is, would an xspc x20 450 pump/reservoir be powerful enough to have two rads on the loop, and in the future have a GPU waterblock on it? Thanks in advance.
