There is a lot of variety... Most 360 AIO will do much better than any air cooler with less noise. Many 240-280 will as well... Good/Great air coolers will often do as well as a 120-240mm aio. This will vary by radiator size/thickness, the fans and the case airflow and any obstructions. Personally, O11 dynamic, with a 360 aio at the top/exhaust and 3x side, 3x bottom intake... It's really quite pretty much all the time... If I stick my head close, I can hear a little hum, but that my well be the video card for all I can tell. The 4-bay nas on the shelf nearby is more noticeable.
