Fans 40x40x20mm DC12V 0.8W 3-wire Server Cooling Fan 100pcs

SKU CH-4ECY-0509X

A bulk pack of one hundred 40 mm square DC12V case fans, each 20 mm thick with a three-wire connection and .8 W draw

  • Compact 40x40x20mm size fits tight server chassis
  • Low 0.8W draw reduces power load per unit
  • 3-wire connection enables speed monitoring and control
  • 100-piece bulk pack suits rack-scale deployments

40×40×20 mm 12 V server fans bulk pack

These 100 DC 12 V fans measure 40 by 40 by 20 mm and draw 0.8 W each. The three-wire connection provides speed feedback for server and industrial chassis. They are sold new in a single lot for high-density cooling deployments.

Direct replacement for identical 40 mm frames

The drop-in size matches existing 40×40×20 mm bays so no bracket changes are needed. The upgrade is worth it when current units have failed or run louder than 0.8 W models allow. Buyers who need larger airflow or different voltage should look elsewhere.

How do I connect the three-wire lead to a 12 V header?
