Black 120 mm PWM case fan with nine translucent blades and a square frame

ARCTIC

ARCTIC F12 PWM 120 mm Case Fan Black

SKU CH-E5NQ-AX16Y

A 120 mm PWM case fan with 230–1350 RPM speed, 53 CFM airflow and 0.3 Sone noise for quiet, adjustable cooling

  • PWM control matches fan speed to cooling demand for quieter operation
  • Innovative blade design delivers strong airflow while keeping noise low
  • Two-way installation lets you exhaust heat or intake cool air
  • Fluid dynamic bearing with oil capsule provides long service life
  • Runs at 230-1350 RPM with 53 CFM airflow at maximum speed

120 mm PWM Case Fan

The ARCTIC F12 PWM is a 120 mm case fan built for system builders who want reliable airflow with low acoustic output. A 4-pin PWM connector lets the motherboard control speed automatically from 230 to 1350 RPM. The impeller design targets efficient ventilation while keeping turbulence low. A fluid dynamic bearing with an oil capsule reduces lubricant leakage for longer service life.

Builders who need quiet, adjustable cooling

This fan suits anyone assembling or upgrading a desktop who wants the motherboard to manage fan speed without manual intervention. The two-way mounting option supports both intake and exhaust configurations. Buyers who require higher static pressure for dense radiators or restrictive filters should look at specialised models. Users without a 4-pin PWM header on their board cannot use the automatic regulation feature.

Airflow and noise headroom

At full speed the fan moves 53 CFM or 90.1 m³/h with a noise level of 0.3 Sone. The wide 230–1350 RPM range provides headroom for silent idle operation and stronger airflow under load. The bearing design maintains consistent performance over time without the wear typical of simpler sleeve bearings. In very restrictive layouts the available pressure may become the limiting factor.

Questions about this item

Does my motherboard need a 4-pin PWM header to control the fan speed?

Yes, the fan uses a 4-pin PWM connector so the motherboard can regulate speed between 230 and 1350 RPM.

Can I run this 120 mm fan at low RPM alongside older 3-pin fans on the same controller?

The PWM signal lets the motherboard set precise speeds down to 230 RPM, while 3-pin fans on the same header will run at full voltage unless the board supports voltage control.

How do I confirm the fan is spinning at the correct speed after installation?

Check the BIOS or monitoring software; it should report a speed between 230 and 1350 RPM matching the PWM duty cycle set by the motherboard.
