- Airflow rate40-45 CFM
- Delivers 45.9 CFM airflow at 4000 RPM for effective case cooling
- Runs at just 40 dBA for quiet desktop operation
- Consumes only 3.86 W at 0.29 A actual current
- Fits standard 80 x 80 x 25 mm mounting points
- Operates reliably from 6.0 V to 13.8 V input range
Compact 80 mm axial fan for tight chassis
The NMB 3110KL-04W-B70/B79 measures 80 by 80 by 25 mm and runs on 12 V DC. It draws 0.38 A rated current with an actual draw of 0.29 A. The fan spins at 4000 RPM and weighs 95 g. It suits builds where installation depth is limited and low noise matters.
Airflow rating 40 to 45 CFM
The single figure that decides fit is the 40 to 45 CFM air volume at 40 dBA. That throughput handles moderate component heat in small enclosures. If the thermal load demands substantially more airflow this fan will not meet it.
Mounts in standard 80 mm case openings
Four corner holes align with typical 80 mm fan grilles on cases or heatsinks. The 6.0 to 13.8 V operating range lets it run from a motherboard header or a fan controller. Low 3.86 W power draw frees headroom on the 12 V rail for other components.

Questions about this item
How much air does the 45.9 CFM rating actually move inside a case?
It delivers 45.9 CFM at 4000 RPM, shifting enough volume to cool compact heat exchangers or tight drive bays.
What does the 6.0 V to 13.8 V operating range mean for motherboard control?
The fan starts at 6.0 V and runs up to 13.8 V, so PWM or voltage headers can vary speed across the full range.
Will the 80 mm by 25 mm frame fit standard 80 mm mounting holes?
Yes — the 80 mm square frame with 25 mm depth matches the common 80 mm hole pattern used on cases and radiators.
