  • Hybrid hydraulic bearing with dual oil circuits lasts longer
  • PWM range 500-2200 RPM gives precise speed control

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

The Sudokoo MACH140 US is a 140mm case fan with a 30mm thick frame designed for high static pressure. It uses a 3-phase 10-pole 12-slot FOC motor with neodymium magnets and a 4-pin PWM connector for speed control between 500 and 2200 RPM. This single fan targets builders who need focused airflow through dense fin stacks or radiators.

LCP blades and hybrid hydraulic bearing

Liquid Crystal Polymer blades reinforced with 40% glass fibre resist warping at high RPM. The custom hybrid hydraulic bearing from PORITE CORPORATION uses dual oil circuits and brass tubes for durability. The 4-pin PWM connector allows motherboard speed control down to 0 RPM below 5% duty cycle. A transparent motor window houses switchable white LEDs for visual customisation.

Practical limits of the 4-pin PWM interface

Maximum airflow reaches 129 CFM at 2200 RPM with 5.91 mmAq static pressure. Noise stays under 39.9 dB(A) at full speed. The fan draws 0.45 A at 12 VDC for 5.4 W total power. Buyers who need higher airflow at lower noise or who require a bundled fan controller will not find those features here.

Questions about this item

What does the 4-pin PWM connector let me control, and what speed range does it actually cover?

The 4-pin PWM connector enables motherboard speed control from 500 to 2200 RPM ±10%, and the fan can stop completely below 5% PWM duty cycle.

Will the 30 mm thick frame and 140 mm square dimensions fit my case and clear my CPU cooler?

The fan measures 140×140×30 mm, so verify your case supports 30 mm thick 140 mm mounts and that the cooler has at least 30 mm clearance above the heatsink.

How do I install the fan correctly, and what orientation mistake should I avoid?

Mount with the four corner screws using the arrows on the frame: the arrow pointing along the blade curve shows airflow direction, so aim it toward the heatsink or exhaust vent.
