After installing all of the components onto the motherboard and installing it in the Corsair 400r, I decided to install my radiator next with the fans attatched... then a problem arose. One of the 120mm fans on the radiator was causing the radiator to be unable to fit inside of the case because of a heat sync on the motherboard. From what I see, the fan is a 120mm X 120mm X25mm dimension. I've talked to a local computer shop guy (who was highly against watercooling.. strange), who said I should send my H100i back and just get a different cooler. On the other hand, I've done some research, and have seen where some manufacturers make slimmer fans, in the 12-14.5mm range. What do you guys suggest?

**note** Currently, I have the one fan that actually is able to be on the radiator helping me cool my CPU, which, those temps at idle, at 4.0GHz are roughly 40C.
