The efficiency test, in which we test what the airflow is at a set noise level of 30 dB(A), is in our opinion the most important, because we prefer to see coolers that are silent and cool well. The best ones are the Noctua NF-A14 industrialPPC-2000 140mm IP67 PWM and the Noiseblocker NB eLoop 140mm 1200 rpm PWM, which produce 32.7 cfm at 30 dB(A). The first one is relatively expensive, but aimed at industrial application and moreover waterproof.
"The most efficient and thus "best" 140mm fans are the Noctua NF-A14 industrialPPC-2000 140mm IP67 PWM and the Noiseblocker NB-eLoop 140mm 1200rpm PWM. Both deserve an Ultimate award." (Farzin Parham, Hardware.Info)
