Phanteks PH-F140SK_DRGB_PWM_3P 3-pack 140mm case fans

Three 140 mm high-airflow fans

This three-pack supplies three 140 mm case fans with a nine-blade design rated at 84.5 CFM. Each unit runs on a 4-pin PWM connector and a rifle bearing, allowing speed control from 500 to 1500 RPM. Digital RGB LEDs on every fan can be daisy-chained via the included 3-pin D-RGB cable for motherboard or controller sync. The rigid frame and 24 rubber dampeners are intended to reduce vibration in standard chassis builds.

Thermals noise and power draw

At the rated 1500 RPM the fans move 84.5 CFM while producing 30.3 dB(A) of noise. PWM control lets the curve drop to 500 RPM for quieter idle operation without disabling airflow entirely. The 4-pin connector draws power directly from the motherboard header, so no separate fan controller is required. Rubber pads on all mounting points further isolate motor vibration from the case panels.

Sustained load behaviour

Under continuous load the nine-blade geometry maintains the stated airflow figure while the rifle bearing keeps acoustic output steady at the published 30.3 dB(A). PWM response adjusts speed within the 500 to 1500 RPM band to match thermal demand without abrupt rpm spikes. The rigid frame resists flex during prolonged high-speed rotation, keeping vibration damping effective over time. Daisy-chained D-RGB lighting remains synchronised across all three fans during extended use.
