Fans AFB1212MJ-00 12025 12V 0.4A 4-wire case fan

SKU CH-GR09-5M0GB

120 mm case fan runs on 12 V at 0.4 A with 4-wire PWM control

  • 12 V 0.4 A four-wire PWM control for precise speed regulation
  • 12025 frame fits standard 12 cm mounting points in cases and projectors
  • New condition ensures full rated performance from first power-on
  • 4-wire interface enables motherboard monitoring and automatic fan curves

12 cm 12 V 4-wire cooling fan

The AFB1212MJ-00 is a 12 cm case fan that runs on 12 V and draws 0.4 A through a 4-wire PWM connection. It is suited to system builders who need a standard 12025 frame for chassis or radiator airflow. The unit is supplied new and ready for installation.

PWM speed control via 4-wire lead

The 4-wire cable enables motherboard PWM control so fan speed can scale with temperature without extra adapters. Buyers who require a 3-pin voltage-only header or a bundled splitter cable will not find those included. No lighting, rubber mounts or additional accessories are provided.

Questions about this item

Will the 4-wire PWM header on the AFB1212MJ-00 need periodic cleaning or bearing lubrication?

The fan uses a sealed bearing design that does not require lubrication; only occasional dust removal from the blades and frame is needed to maintain airflow.

What thermal or electrical limit appears first when the AFB1212MJ-00 runs continuously at 12 V and 0.4 A?

The motor is rated for 12 V and 0.4 A, so sustained operation at those levels stays within its specified electrical envelope; the first practical limit is dust buildup reducing static pressure over time.
