SKU CH-KNC0-43H4H

A 40 mm square server cooling fan operating at 12 V with 1.6 W power draw

  • 12 V 1.6 W power draw keeps server cooling efficient
  • 40 x 40 x 20 mm footprint fits tight 4020 chassis slots
  • New condition ensures reliable airflow from first spin
  • Internal power cable design simplifies server fan installation

40 × 40 mm 12 V server cooling fan

This 40 mm square fan runs on 12 V and draws 1.6 W, making it suitable for compact server chassis and network appliances that need focused airflow. The 4020 frame profile fits standard 40 × 40 × 20 mm mounting holes.

Simple two-wire installation

Connect the two power leads to a 12 V header or Molex adapter; polarity must be observed to avoid damage. The thin 20 mm depth can catch on adjacent cables in dense backplanes, so verify clearance before securing the screws.
