Set fan speed to 40 and they are just about silent

At full power they are very noisy but they also move a lot of air

It can be quite loud on full speed although not needed for me

Unfortunately my experience the 2 corsair co9050046ww ml series ml140 pro led white 140 both units i had gave a low to medium level high pitch increasing buzz whine from 6001350rpm not loud but you do or can hear it all the timeif youre in a moderately loud room or if your pc is on the floor under a desk a meter or more you will hear nothing so all is good but in a quiet room once you hear thar whine its there all the time you notice it all the timebuild quality is good and the airflow is high and yes its a highpressure flow very easy to installat 1500rpm and above the highpressure airflow can be heard across the room it does ger a bit noisy but preferable to the high pitch whine and yes the high air flow at 1500rpm does mask over the whine buzz completely
