I'm currently using Corsair Air 540. I need a new motherboard/cpu and debating if I should go to a new case. I like how much room the 540 has but even with all fans being Noctua 140s (2 in, 1 out, 2 on NH-D15), I hear more than I'd like. GPU isn't the noise it seems, RTX2080 with idle fans most times on the desktop. I need to be able to mount a 2.5" and 3.5" drive, and preferably an optical drive. As mentioned, using a tall CPU cooler, Noctua NH-D15. Power supply is a very quiet EVGA 650watt. I don't know what I'm hearing, other than maybe just the airflow through a thin, cheapish case. And it doesnt help that the PC is only 3' from my head. What case should I look at? as long as the width is not greater than the Air 540 (and frankly, what case is wider than this thing?) size isn't a concern. I was looking at the higher end BeQuiet! cases but the reviews were middling. If the case comes with less than great fans, as long as they are 140mm I'll just move over these Noctuas.
