SKU CH-CH9Y-F1VEV MPN 4715KL-04W-B20

A 120 mm case fan delivering 97 CFM at 2650 RPM with a 41 dBA noise level and double ball bearing

  • Strong airflow for demanding cooling with 97 CFM output
  • Quiet operation at 41 dBA suits noise-sensitive builds
  • Double ball bearing ensures long service life
  • 12 V 0.52 A design fits standard chassis headers
  • Wide -10 to 70 °C range handles harsh environments

Industrial-grade cooling fan

The NMB 4715KL-04W-B20 is a 12038 frame axial fan built for chassis cooling in medical, rail, industrial and new-energy vehicle applications. It runs on 12 V and draws 0.52 A rated current. Double ball bearings support continuous operation across a -10 to 70 °C working range.

97 CFM airflow at 2650 RPM

The single specification that decides fit is the 97 CFM air volume delivered at 2650 RPM. That flow rate must match the thermal load of the enclosure you are cooling. If the system requires significantly more or less airflow, a different fan model is needed.

41 dBA steady-state noise

Under sustained load the fan maintains its rated speed and airflow while producing 41 dBA of acoustic noise. The double ball bearing design keeps speed stable over long duty cycles without the slowdown that sleeve bearings exhibit when lubricant ages.

Questions about this item

What does 97 CFM mean for airflow inside my case?

97 CFM indicates the fan moves roughly 2.75 cubic metres of air per minute at 2650 RPM, providing strong directional cooling for dense component layouts.

How does the 12 V 0.52 A rating affect motherboard header compatibility?

The fan draws 0.52 A at 12 V, so a standard 1 A PWM or DC header can supply it; actual running current is lower at 0.4 A.

Will the 120 × 120 × 38 mm frame fit my 120 mm mounting points?

The 120 mm square footprint matches standard 120 mm holes, but the 38 mm thickness requires clearance behind the motherboard tray or radiator.
