  • Dual ball-bearing design extends operational life

  • 5500 RPM delivers 28.18 CFM airflow for effective cooling
  • Compact 4010 form factor fits tight chassis spaces

Compact 4010 axial fan for tight builds

This 40 mm by 10 mm fan runs on 12 V and draws 0.14 A, spinning at 5500 RPM to deliver 28.18 CFM of airflow. The dual ball-bearing design targets continuous operation in small enclosures where space is at a premium.

Practical limits of the 12 V two-wire interface

Speed is fixed at 5500 RPM with no PWM or voltage-control signal, so airflow cannot be adjusted by the motherboard. The 0.14 A draw suits standard fan headers, but the lack of a tachometer wire means the system cannot monitor rotation or trigger alerts if the fan stops.

Questions about this item

Should I choose the 4010 or a different size for my build?

The 4010 designation means a 40 mm frame with 10 mm thickness, so verify your case or heatsink has mounting holes for that exact footprint before ordering.

What does the 5500 RPM rating mean for actual airflow and noise?

At 5500 RPM the fan moves 28.18 CFM through a 40 mm frame, delivering strong spot cooling for tight spaces while the dual ball bearing keeps running noise consistent over time.
