A 51 mm 12 V 4-wire case fan drawing 0.15 A for server cooling

  • 4-wire PWM control for precise speed adjustment
  • 12 V DC operation matches standard PSU rails
  • Low 0.15 A draw keeps power use minimal
  • 51 mm frame fits tight server chassis

12 V 4-wire server cooler

This 12 V 4-wire fan is built for server and workstation chassis that demand constant airflow. The 0.15 A draw keeps power use low while the PWM connection allows the motherboard to scale speed with thermal load. It suits administrators who need reliable cooling in rack-mounted or pedestal systems.

Fits standard 12 V PWM headers

The four-pin connector plugs directly into a 12 V PWM header on a server board or compatible controller, so no adapter is required. Speed regulation is handled by the host system, freeing a 3-pin header for simpler devices. Builders who need voltage-only control or a different pin layout should choose another model.
