SKU CH-DEM4-7G2D4

A 50 mm square, 15 mm thick 12 V fan with double ball bearings and a 4-pin PWM connector for quiet cooling

  • 12 V power for low-energy operation
  • Double ball bearing extends service life
  • 4-pin PWM enables precise speed control
  • 5015 form factor fits standard 50 mm mounts

12 V 4-Pin Cooling Fan

This 50 mm square fan operates at 12 V and draws 0.11 A. The four-wire connector supports PWM speed control for precise airflow management. It suits compact enclosures that need active cooling in a small footprint. Builders who need higher static pressure or larger frame sizes should look elsewhere.

Double Ball Bearing Construction

Double ball bearings reduce friction and extend service life compared with sleeve alternatives. The 15 mm thickness fits tight mounting brackets without modification. The 4-pin plug connects directly to standard motherboard or controller headers. Users who require a 3-pin voltage-controlled header will need an adapter.

Highlights

  • 12 V power for low-energy operation
