  • 22 A draw keeps system power low
  • Double ball bearing design extends service life
  • 40×40×20 mm footprint suits tight chassis spaces

Compact 40 mm double-ball-bearing case fan

This 40 mm square fan fits the standard 4020 form factor and runs on a 12 V supply drawing 0.22 A. The double ball bearing is designed for continuous operation in tight chassis spaces where a slim 20 mm profile is required. It suits system builders who need a drop-in replacement for small-form-factor enclosures or embedded boards. Buyers who need higher airflow or PWM speed control should look elsewhere because this model provides fixed-speed cooling only.

12 V 0.22 A fixed-speed specification

The single figure that decides fitment is the 12 V 0.22 A power rating; verify that your header or controller can supply this voltage and current before purchase. No PWM wire or voltage-regulation curve is included, so the fan runs at full speed whenever powered. If your design demands variable speed or a different voltage rail, this unit will not meet that requirement.
