Phanteks PH-F120SK_DRGB_PWM_3P 3-pack 120mm case fan

Three-pack 120mm DRGB case fans

This set supplies three Phanteks SK120 DRGB PWM fans for builders who want coordinated airflow and addressable lighting across a chassis. Each unit uses a nine-blade impeller driven by a rifle bearing to move up to 50 CFM while spinning between 500 and 1500 RPM. The 25 mm thick black frames fit standard 120 mm mounting points and include rubber pads to isolate vibration from the case structure.

Motherboard headers and daisy-chain wiring

Verify that your board or controller provides a 4-pin PWM header for speed control and a 3-pin 5 V DRGB header for lighting; the pack includes a DRGB daisy-chain cable and a 4-pin fan extension but no standalone controller. Three fans will occupy three PWM headers or require a splitter, and the DRGB chain needs one motherboard DRGB connector or a compatible Phanteks DRGB hub. Ensure the case has clearance for 120 x 120 x 25 mm fans at each intended location.

Sustained-load acoustics and thermal behaviour

At the rated maximum of 1500 RPM the fans produce 30.3 dB(A) while delivering their peak 50 CFM, so extended gaming or rendering sessions remain relatively quiet for the airflow provided. PWM curves let the firmware lower speed once temperatures stabilise, reducing noise further during long idle or light-load periods. The rifle bearing and rigid frame are designed to maintain consistent speed and low vibration over continuous operation without the rattling that can develop on lesser mounts.
