So I have a corsair air 540 case and the cooling is great even with stock fans. However I have the silver one so it came with LED fans so I'm trying to get rid of those, as well as improving my airflow in my case. But I can't decide as to what fans to get. I am curently looking at the corsairAF140 or cougar CF-V14B. I would get noctua fans but the color scheme is just so ugly IMO plus pricy. I'm sticking to a black/gold/silver theme with my build. Does anyone have any other suggestions for fans? And are the fans I mentioned pretty good?
