Remembering from the table of specifications, the ML120 should put out 75 CFM while making 37 dB doing so.


Here we see that the ML120 puts out a lot more air than spec, and still does not exceed its stated SPL. Further, the eight ML120 fans averaged 61 CFM through a restrictive 30 FPI rad. Not bad.

The ML140 is specified as producing 97 CFM awhile making no more than 37 dB of noise. The eight ML140s definitely accomplished that.


Again, the eight ML140 fans averaged more than 60 CFM through a tight rad. More: when the fans were put in pull position, and air was measured as it entered the box, the eight fans averaged 72.8 CFM. That is, a user will gain 10 CFM by turning these fans over from push to pull. Something to think about.

You might also wonder how well these fans respond to PWM signals from a motherboard. So we tested all the fans at 10% increments, from 1% to 100% of PWM signal.


As you can see, both sets of fans ran flat for a time, then steadily increased as the duty % of the PWM signal was increased.


The noise made by the ML Pro fans do not get transmitted to what they are attached to. They don't sound as loud as they measure.

Silent bearings in fans are usually variations on the sleeve bearing, a design prone to wearing out. As Magnetically Levitated bearings, these are inherently not likely to wear out. Corsair ML fans should last a long time.
