I have a fractal design R4, so I'd prefer a single 120 or 140mm radiator (I can handle a dual radiator but I would have to remove some of the sound proofing and I'm not keen on that). I know that the H80i is a great cooler, but it is $110 for me to buy and about another $40 to ship. I want something under $100. I currently have the noctua NH-D14 so I'd like an improvement, but a quiet improvement.
