SKU CH-24KT-B2E77 MPN 3110KL-05W-B60

8 cm 24 V axial case fan delivers 40.2 CFM at 3400 RPM with 35 dBA noise

  • 24V operation supports wide 10.0–27.6V input range
  • 3400 RPM delivers 40.2 CFM airflow for effective cooling
  • 35 dBA noise level keeps systems quiet under load
  • 14A actual draw at 3.36W reduces power consumption
  • 80×80×25 mm frame fits standard 8 cm mounting points

Purpose and audience

The NMB 3110KL-05W-B60 is an 80 mm axial fan built for 24 V DC systems in industrial, medical and transport equipment. It suits engineers who need a compact, high-speed cooler for tight chassis in rail vehicles, drive enclosures or hotel automation.

Thermals noise and power

At 3400 RPM the fan moves 40.2 CFM while producing 40.2 Pa of static pressure and 35 dBA of noise. It draws 0.18 A at nominal voltage with an actual current of 0.14 A, consuming 3.36 W across a working range of 10.0 V to 27.6 V.

Deciding specification

The 24 V DC rating and 80*80*25 mm frame determine whether this unit fits your power bus and mounting pattern; it is not for 12 V consumer boards or larger 120 mm cut-outs.

Highlights

  • 24V operation supports wide 10.0–27.6V input range

Questions about this item

How do I wire the 24 V fan and what polarity mistake should I avoid?

Connect the red lead to 10.0–27.6 V DC and the black lead to ground; reversing them will prevent the 3400 RPM motor from starting.

Which component wears out first and when should I plan a swap?

The sleeve bearing is the only moving part; replace the unit when acoustic output climbs past the rated 35 dBA or airflow falls below 40.2 CFM.

What thermal limit appears first during continuous 3.36 W operation?

Bearing temperature rise becomes the limiting factor once the 95 g rotor reaches steady state at 3400 RPM.
