140 mm ARGB PWM case fan

The Montech HP140 is a 140 mm white case fan with addressable RGB lighting and a 4-pin PWM connector. It targets builders who want controllable airflow and synchronised lighting in a single unit. The rifle bearing supports a speed range of 600 to 1600 RPM for flexible cooling curves.

White frame with 4-pin PWM control

The fan measures 5.52 inches square by .99 inches thick and uses a standard 4-pin header for motherboard speed control. ARGB illumination connects through a typical 3-pin 5 V header for software synchronisation. White blades and frame suit light-themed builds without extra paint or covers.

90.5 CFM airflow at 29.2 dB

At maximum 1600 RPM the fan moves 90.5 CFM while producing 29.2 dB of noise. Lower PWM duties reduce both airflow and sound for quieter idle operation. The rifle bearing maintains consistent torque across the 600 to 1600 RPM range without lubricant migration.
