I know this may seem like a silly question but I will ask it anyways. I am considering going to an enclosed water cooler like a corsair H70 for my cpu cooler. I know the fan and radiator usually go in the rear of the case where your exhaust fan is. My silly question is this... does using a cooler like this hinder your systems exhaust by using one of the exhaust fans to pull air out of your radiator as well? I have 3 120mm intake fans, the 120mm exhaust in the back and another 140mm exhaust out the top. Any input (or education) would be greatly appreciated.
