Model w/o PWM

  • High airflow of 110.4 CFM cools cases quickly
  • Strong 3.02 mm H2O pressure pushes air through dense fins
  • 2000 RPM maximum speed delivers performance headroom
  • 4 dBA maximum noise keeps operation quiet
  • Dual ball bearing design extends fan lifespan

140 mm PWM case fan for high-static-pressure builds

This 140 mm case fan uses a 4-pin PWM connector and dual ball bearings to deliver up to 2000 RPM. It produces a maximum airflow of 110.4 CFM and a static pressure of 3.02 mm H2O while drawing 0.2 A. The white, non-LED frame measures 140 x 140 x 25 mm and weighs 240 g.

PWM control and noise ceiling at maximum speed

The 4-pin PWM interface lets the motherboard regulate speed automatically, but the fan tops out at 2000 RPM ±10 %. At that ceiling the noise level reaches 31.4 dBA, which may be audible in quiet rooms. Builders who need silent operation at full load should note this upper limit before committing to the fan.

Clearance and header checks before ordering

Verify that your case has 140 mm mounting points with at least 25 mm depth for the frame. Ensure the motherboard provides a 4-pin PWM header for each fan you plan to install. Systems without PWM headers or with restricted clearance around the mounting area will not support this unit.

Questions about this item

Which version of this 140mm fan should I choose?

The TL-B14W EXTREM White comes in a single 140mm non-LED version with a 4-pin PWM connector and dual ball bearing, so there is only one variant to select.

What does the 2000 RPM rating mean once the fan is installed?

At full speed the fan spins up to 2000 RPM ±10%, delivering up to 110.4 CFM airflow and 3.02 mm H2O static pressure while producing a maximum of 31.4 dBA noise.

What does the 4-pin PWM connector cap in practice?

The 4-pin PWM connector allows the motherboard to vary speed precisely from low RPM up to the 2000 RPM limit, so fan curves and thermal control work without voltage restrictions.
