Black 120 mm case fan with transparent rotor and 12 A-RGB LEDs around hub

ARCTIC

ARCTIC P12 PWM PST A-RGB 120 mm Fan Black

SKU CH-7YB5-SAP4X

120 mm PWM fan with 12 A-RGB LEDs, 200-2000 RPM speed range, 48.8 CFM airflow and 1.85 mmH2O static pressure for radiators and heatsinks

  • Digital A-RGB lighting with 12 LEDs for even illumination
  • Y-splitter cables on fan and ARGB simplify multi-fan setups
  • High static pressure of 1.85 mmH2O cools radiators effectively
  • PWM control from 200 to 2000 RPM balances noise and airflow
  • Low noise of 0.3 Sone keeps system quiet under load

PWM case fan with addressable RGB

The ARCTIC P12 PWM PST A-RGB is a 120 mm case fan built for static-pressure workloads such as radiators and dense heatsinks. A 4-pin PWM connector allows speed control from 200 to 2000 rpm, while a semi-passive mode stops the rotor below 5 % duty cycle. Twelve addressable RGB LEDs sit on the hub and transparent rotor for even illumination.

Airflow and pressure headroom

Maximum airflow reaches 48.8 CFM or 82.91 m³/h with a static pressure of 1.85 mmH2O, enough for restrictive radiator fins. Noise stays at 0.3 Sone at typical speeds, rising only when the curve demands full RPM. The fan runs out of headroom when system resistance exceeds its pressure curve or when airflow demand surpasses the rated maximum.

Y-splitter cables and mounting

Both the PWM and 5 V 3-pin ARGB leads include integrated Y-splitters, so additional fans can be daisy-chained without extra hubs. Standard 120 mm mounting holes fit any compatible case, radiator or heatsink. The enclosed rotor design keeps cables tidy and protects the LED diffuser during installation.

Questions about this item

Will the 4-pin PWM connector on this fan work with my older motherboard that only has 3-pin headers?

Yes, the 4-pin PWM connector is backward compatible with 3-pin headers; the fan will run at full speed without PWM control.

How can I verify the semi-passive mode is active and the fan stops below 5% PWM duty?

At very low PWM values the fan should stop spinning completely while the 12 A-RGB LEDs remain lit, confirming the 0 RPM mode is functioning.

Does the package include the 5V 3-pin A-RGB cable and Y-splitters for daisy-chaining multiple fans?

Yes, both the fan cable and the A-RGB cable have integrated Y-splitters in the box, so no extra cables are needed to chain additional units.
