I got a 4930k and a corsair H110 which I am turning into a push pull config. I just ordered the rampage IV black edition and wanted to use noctua NF A14 PWN but noticed they are 4 pin. They do have 3 pin noctua NF A14 FLX should I get those instead for my push pull config? Are 4 pin only for cpu fans? Would it handle 4 of them? I am not looking to change rpm of fans I want them running at max speed at all times. Which ones should I get and why for my h110?
