The market for case fans offers a lot of choices, but this makes the search for an appropriate case fan even harder. We tested 71 140mm case fans to clear up the situation.

Last year, we tested 103 120mm case fans. This year, the 140 mm models are up for assessment. The advantage of bigger fans is that, on average, they need fewer rpm than smaller fans to create the same air flow. Because of this they should be less noisy with the same airflow and are thus more efficient. So, if your case supports 140mm as wel as 120mm fans, the choice will be a no-brainer.

Besides the pros, there are cons: cases often have less positions for 140mm fans than for 120mm fans. So, it is smart to check the number of positions for 140mm fans your case has before buying new fans.
