I need suggestions for a good airflow fan to replace it, that actually is mounted via 140mm and not 120mm. I would prefer more air movement rather than quietness, but if there is one with an excellent combo of both I would like to hear of it as well.
Coolermaster's 140mm works pretty well. I've used them in a couple of cases. It is 60cfm, which is more than you'll need most of the time assuming you have at least 2 fans and it is quiet which is nice even when not a priority
