  • Ultra-quiet cooling at just 26 dBA noise
  • Compact 40x40x10 mm frame fits tight spaces
  • Reliable ball-bearing motor rated for long life
  • Efficient 5 V operation draws only 0.6 W

SUNON KD0505PFB3 5V 0.6W 40x40x10mm ball bearing fan

This 40 mm axial fan runs on 5 V DC and draws 0.18 A for a rated input power of 0.6 W. It spins at 6500 RPM to deliver 6.5 CFM of airflow while producing 26 dBA of noise. The unit uses a ball bearing and a 2-pin connector for power.

Verify voltage connector

Confirm that your device supplies 5 V DC and accepts a 2-pin power header. The frame measures 40 mm square by 10 mm thick, so ensure the mounting holes and clearance match this footprint. The 0.18 A current draw should be within the header’s rated limit.

Suits tight 5 V cooling spots like small

Builders needing a compact 5 V fan for restricted spaces will find the 40x40x10 mm size and low 0.6 W draw suitable. Buyers who require higher airflow, lower noise, PWM speed control or a 3-pin or 4-pin connector should look at alternative models.

Questions about this item

What comes with the 5010 5V fan and what must I source separately?

The fan itself is supplied with a 2-pin connector; mounting screws, a 5 V power source and any fan controller or splitter are not included.

How do I choose between the KD0504PFB2-8 and KD0505PFB3 models listed?

Both share 40×40×10 mm dimensions, 5 V operation, 0.18 A draw, 0.6 W input, 6500 RPM speed, 6.5 CFM airflow and 26 dBA noise; select the part number that matches your existing wiring or vendor stock.

What does the 6.5 CFM airflow rating mean once the fan is installed in a case?

At 6500 RPM the fan moves 6.5 cubic feet of air per minute through an unrestricted opening; actual throughput inside a chassis will be lower due to grilles, filters and component obstructions.
