be quiet! Silent Wings Pro 4 140mm PWM vs EKWB EK-Loop Fan FPT 120: Comparison
be quiet! Silent Wings Pro 4 140mm PWM vs EKWB EK-Loop Fan FPT 120 airflow compared
The gap that matters here is airflow: be quiet! Silent Wings Pro 4 140mm PWM 97.4 CFM against EKWB EK-Loop Fan FPT 120 77 CFM, which puts be quiet! Silent Wings Pro 4 140mm PWM 21% ahead. be quiet! Silent Wings Pro 4 140mm PWM also leads on static pressure, 3.64 mmH2O on the be quiet! Silent Wings Pro 4 140mm PWM versus 2.7 mmH2O on the EKWB EK-Loop Fan FPT 120. They differ on rated life too, 300000 hours on the be quiet! Silent Wings Pro 4 140mm PWM versus 60000 hours on the EKWB EK-Loop Fan FPT 120.
be quiet! Silent Wings Pro 4 140mm PWM vs EKWB EK-Loop Fan FPT 120: which one fits your build
Buy the be quiet! Silent Wings Pro 4 140mm PWM for 280mm and 420mm AIO radiators and Quiet high-pressure builds, though it is not the pick for RGB-focused builds and open mesh cases where pressure is wasted. The EKWB EK-Loop Fan FPT 120 is the one to take for custom water-cooling loop radiators and thick, high-FPI radiator duty, though it is the wrong buy for general case intake or exhaust duty and Quiet-first builds. Our rating of the be quiet! Silent Wings Pro 4 140mm PWM (9/10): one of the strongest 140mm radiator fans available, at the cost of skipping RGB entirely. Our rating of the EKWB EK-Loop Fan FPT 120 (8/10): A strong purpose-built fan for custom loop radiators, less relevant outside that use case.
Where the two are identical
The common ground is wider than the gap: bearing type, connector type, pwm control and colorway are identical here.
