SKU CH-3TMQ-159W9 MPN AD0405MB-G70

A 40 mm axial fan with double ball bearings runs on 5 V and 0.11 A for compact CPU cooling

  • Compact 40×40×10 mm frame fits tight CPU cooler builds
  • Double ball bearing extends service life in continuous operation
  • Low 0.11 A draw keeps 5 V rail headroom for other components
  • Industrial-grade ADDA motor rated for medical and rail vehicle use
  • Two-wire DC 5 V power simplifies wiring in custom cooling loops

Compact 40 mm cooling fan

The Fans AD0405MB-G70 is a 4010 frame axial fan built for 5 V DC systems that need a low-profile airflow solution. It draws 0.11 A and uses a double-ball bearing for durable rotation in continuous-duty environments.

5 V two-wire power constraint

Operation is limited to a 5 V DC two-wire supply, so the fan cannot be driven directly from 12 V headers or PWM controllers without external regulation. The fixed voltage and current rating set a hard ceiling on maximum speed and airflow.

Replaces sleeve-bearing 4010 fans

This unit upgrades older 4010 fans that use sleeve bearings and higher failure rates in vibration-prone chassis. The jump is worth it when the application demands longer service intervals and consistent speed under variable temperatures.
