Enermax T.B.Silence PWM (120mm/68.4 CFM/1.79 mmH2O Static Pressure/1500 RPM Max/19.3 dBA/Twister Bearing/No RGB/PWM) Review

Enermax's T.B.Silence PWM comes up for anyone chasing high airflow at a genuinely low noise floor, its Twister bearing blades are built specifically to cut turbulence noise.

It's one of the quietest fans at this airflow level we've seen, a strong pick if noise matters more to you than lighting.

Comparison to Alternatives

Against the Noctua NF-A12x25 PWM already in our catalog, the T.B.Silence delivers similar airflow at a comparable noise level for meaningfully less money, though it lacks Noctua's SSO2 bearing longevity data. Compared with the Fractal Design Dynamic X2 GP-14 PWM, the Enermax pushes more airflow at a similar dBA rating despite being a smaller 120mm fan.
