Corsair ML140 PRO RGB (140mm/55.4 CFM/1.87 mmH2O Static Pressure/1200 RPM Max/20.4 dBA/Magnetic Levitation Bearing/RGB/PWM) Review

Corsair ML140 PRO RGB 140mm case fan, 55.4 CFM airflow, 1.87 mmH2O static pressure, 1200 RPM max, 20.4 dBA, Magnetic Levitation bearing, RGB, PWM control. A 140mm magnetic-levitation fan tuned for quiet running with four RGB LEDs.

The ML140 PRO RGB scales Corsair's maglev bearing design up to 140mm and trades the ML120's aggressive top speed for a calmer 1200 RPM ceiling, landing it firmly in the quiet-case-fan category rather than the radiator-fan category. At 20.4 dBA it's one of the quieter RGB fans Corsair sells, useful for builders who want lighting without the fan noise that often comes with it.

Tuned for Quiet, Not Pressure

Where the 120mm ML PRO variant is often chosen for radiators, the 140mm version's lower 1200 RPM ceiling and larger blade diameter push it toward case-airflow duty instead — it simply doesn't spin fast enough to be a strong high-restriction radiator performer.

RGB Without the Noise Trade-off

Four RGB LEDs per fan give a bright, even glow through a case window, and because the fan tops out at a modest 20.4 dBA even at full speed, adding lighting here doesn't come with the usual noise penalty of high-RPM RGB fans.

Comparison to Alternatives

Against the Corsair AF140 Elite, the ML140 PRO RGB is the quieter maglev option but moves noticeably less air (55.4 CFM vs. 84.5 CFM) — the AF140 Elite is the better pick for pure case airflow. Versus the be quiet! Light Wings 140mm PWM high-speed, the ML140 PRO RGB is quieter at max speed but the Light Wings pushes more CFM for builders who need stronger airflow.

Expert Review

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

Expert rating8 / 10

A quiet, glowing 140mm fan best suited to case airflow rather than radiator duty.

Best for

  • Quiet RGB case airflow
  • Builders who dislike loud RGB fans
  • 140mm intake/exhaust roles

Not for

  • Thick radiator duty (insufficient static pressure)
  • Maximum-CFM case airflow
  • Non-RGB builds

FAQs
