I just ordered an NZXT H440, and I wanted to upgrade the fans from stock. I was looking mainly for silence, and I found these two fans: be quiet! PURE WINGS 2 and Noctua A-14 FLX. I was planning on using either 3 Noctuas (one on back and two in front) or 5 be quiet!s (2 in front and 3 in back). Both setups cost around the same, and I was wondering which would be worth my money. Any help would be appreciated.
