140 mm PWM case fan with 12-pole motor

This 140 mm case fan uses a three-phase 12-pole DC motor and a 30 mm thick frame built from reinforced Liquid Crystal Polymer for rigidity. PWM control lets the system adjust speed automatically, and a supplied remote controller offers silent, mid and extreme profiles. It is aimed at builders who want a thick, high-airflow fan for chassis intake or exhaust.

Check PWM header and 30 mm clearance

Verify that your motherboard has a free 4-pin PWM header to enable automatic speed curves and remote-profile switching. Measure the mounting location to confirm 30 mm of depth is available, as the thicker frame may interfere with side-panel cables, radiator brackets or tall memory modules. The included anti-vibration pads add a small amount of extra height.

Sustained airflow at fixed PWM duty

Under continuous load the 12-pole motor maintains a steady torque curve, so airflow remains consistent once the PWM duty cycle settles. The reinforced LCP blades resist flexing at higher RPM, preventing the drop-off sometimes seen in thinner fans during long sessions. Acoustic output stays predictable because the motor topology avoids the harmonics that appear in shorter bursts.

Questions sur cet article

Does the SF-PF141-BK include the PWM controller and anti-vibration pads, or must I buy them separately?

The fan ships with anti-vibration mounting pads and a remote PWM controller so you can switch between silent, mid and extreme profiles without extra purchases.

The listing mentions 12-pole motor and 30 mm depth — which version should I pick for maximum airflow?

This is the only version offered: a 140 mm frame, 30 mm thick, 12-pole motor design; there are no alternative capacities or thinner models to choose from.

What does the 12-pole motor actually deliver once the fan is installed in a case?

The 3-phase 12-pole motor drives the reinforced LCP blades at three selectable profiles, moving more air at lower noise than conventional 4-pole designs of the same 140 mm size.
