Grey and white 140 mm case fan with pressure-optimised blades and PWM sharing technology

ARCTIC

ARCTIC BioniX P140 140 mm case fan Grey/White 200–1950 RPM

SKU CH-5W6V-5F1YK

A 140 mm case fan with a pressure-optimised design, 200–1950 RPM speed range and PWM sharing for synchronous control

  • Pressure-optimised design suits radiators and filters
  • 200–1950 RPM range with PWM sharing for synchronous control
  • Motor runs at 10 °C lower temperature for four times longer life
  • Commutation vibrations cut to 5 % of a conventional DC motor
  • 45 Sone noise level at maximum speed

140 mm pressure-optimised case fan

The ARCTIC BioniX P140 is a 140 mm case fan built for static-pressure tasks such as radiators, heat sinks and filtered intakes. It runs from 200 to 1950 RPM and uses a four-pin PWM connector with PWM Sharing Technology so multiple fans can be synchronised from a single header. The grey and white finish suits neutral build themes. A newly developed motor design cuts commutation vibration to roughly five percent of a conventional DC motor, removing the need for rubber dampers.

Who this suits and who should look elsewhere

Builders who need strong static pressure for liquid-cooling radiators or dense heatsinks will benefit from the pressure-optimised blade profile. The wide speed range also helps systems that demand near-silent idle and high airflow under load. Buyers who want maximum airflow volume for unrestricted case ventilation may prefer a fan tuned for airflow rather than pressure.

200–1950 RPM speed range with four-pin PWM control

The fan operates between 200 and 1950 RPM, delivering 776 CFM at top speed while producing 0.45 Sone. The four-pin PWM interface enables precise motherboard control and daisy-chaining via PWM Sharing Technology. Lower motor temperature is cited as giving a four-times longer service life compared to conventional designs.

Questions about this item

What motherboard header is needed to run the 4-pin PWM fan at speeds between 200 and 1950 RPM?

A standard 4-pin PWM header on the motherboard or fan controller supplies the signal that lets the fan vary from 200 to 1950 RPM.

Will the PST function let this fan match speeds with older 3-pin or 4-pin fans already in the case?

PST passes the PWM signal through the daisy-chain connector so every linked fan — regardless of age or pin count — follows the same curve.

How can I confirm the fan is spinning at the intended RPM once the system is running?

Read the RPM value in BIOS or any hardware-monitoring utility; it should sit within the 200–1950 RPM range under the current PWM duty cycle.
