Enermax T.B.Silence PWM vs NZXT F140Q Quiet: Comparison
Enermax T.B.Silence PWM vs NZXT F140Q Quiet airflow compared
On airflow the spread is 31%, Enermax T.B.Silence PWM 71.25 CFM against NZXT F140Q Quiet 102.9 CFM, so NZXT F140Q Quiet takes it. There is a split on bearing type as well, Twister on the Enermax T.B.Silence PWM versus Fluid Dynamic on the NZXT F140Q Quiet. Rated life is not the same on both, 160000 hours on the Enermax T.B.Silence PWM versus 60000 hours on the NZXT F140Q Quiet. They differ on positioning too, Mainstream on the Enermax T.B.Silence PWM versus Quiet mainstream on the NZXT F140Q Quiet.
Which should you buy, Enermax T.B.Silence PWM or NZXT F140Q Quiet?
The Enermax T.B.Silence PWM suits silent, high-airflow builds and budget-conscious quiet builds, though it is not built for RGB-focused builds and high static pressure radiator duty. Buy the NZXT F140Q Quiet for Quiet builds inside NZXT H-series cases with 140mm mounts and open intake or top exhaust positions, though it is not the pick for radiator or filtered-intake duty needing pressure and RGB or showcase builds. Our rating of the Enermax T.B.Silence PWM (8/10): an excellent value pick for anyone who wants Noctua-like quiet airflow without the Noctua price tag. Our rating of the NZXT F140Q Quiet (7/10): A dependable quiet 140mm fan for NZXT case owners prioritizing low noise over lighting or raw airflow.
Where the two are identical
Everything else lines up. Connector type, lighting, fan thickness, max speed and pwm control read the same on both, so those are not worth weighing. They match on 1 further specification as well.
