Enermax T.B.Silence PWM Review

The Enermax T.B.Silence PWM is a 120mm non-RGB case fan with a Twister bearing, PWM control, 71.25 CFM airflow, 1.676 mmH2O static pressure, 1500 RPM maximum and 19.3 dBA noise.

A quiet-first fan with no lighting. It reaches 71.25 CFM at 1500 RPM while staying at 19.3 dBA. Speed runs from 500 RPM, set through a 4-pin PWM header, though the specs list no zero RPM mode. Static pressure is 1.676 mmH2O. It is 25 mm thick with a rated life of 160000 hours and a listed maximum power draw of 4.8 W. It suits builds where noise matters more than looks.

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.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Expert rating8 / 10

An excellent value pick for anyone who wants Noctua-like quiet airflow without the Noctua price tag.

Best for

  • Silent, high-airflow builds
  • Budget-conscious quiet builds
  • General case intake/exhaust

Not for

  • RGB-focused builds
  • High static pressure radiator duty
  • Show-window builds
