[SOLVED] 2x 120mm fans v. 1x 240mm

Which one will cool better?

The single 240mm will move more air. Do the math:

240 x 240 vs. 120 x 240

Each fan should have an airflow (CFM) and nose (dBA) rating. Just compare those. But yeah, I don't see 2x120mm fans (or even 4 to match the area) moving as much air as a 240mm one.

The thing I don't like about 200+mm fans is that I feel they get TOO big and the bearing can't stabilize them as well. They often feel chintzy.

Im assuming this is about 120mm AIO vs 240mm AIOs, not fans.
