I am upgrading my case and decided that I will be buying the corsair 450D. Now, the 450D comes with 2 AF140l's as intake and 1 AF120 as exhaust at the back. My question is should I replace the from AF140's with Noctua NF-A14's or should I just leave them. Because of the open mesh in the front of the case, they might the noctuas will be very visible but I have heard that the corsairs are very loud. On another note, I plan to get the NH-U14s cooler so the noctuas will match in terms of color
