Compact 40 mm cooling fan

The OEM Industries PAAD14010SM is a 40 mm DC fan built for tight spaces in industrial or embedded systems. It runs on 12 V and draws 0.16 A, delivering 6600 RPM airflow in a sleeve-bearing design. Buyers needing larger diameters or higher static pressure should look elsewhere.

Three-wire connection with speed monitoring

The 3-wire lead supplies power, ground and a tachometer signal so the host can monitor fan speed in real time. No RGB lighting or PWM control is included, keeping the wiring simple for basic thermal management. Systems requiring 4-pin PWM regulation or addressable lighting will not benefit from this model.

7.97 CFM at 31 dBA noise level

At full speed the fan moves 7.97 CFM while producing 31 dBA, a level suited to small enclosures where modest airflow is sufficient. It is not intended for high-heat CPUs or multi-core workloads that demand greater cooling capacity. Applications requiring substantially more airflow or lower acoustic output will exceed what this unit can provide.

Questions about this item

How often should the sleeve bearing in this 40 mm fan be replaced?

Sleeve bearings are not user-serviceable; plan to replace the entire fan when noise or vibration increases beyond the rated 31 dBA.

At the rated 6600 RPM, what limit appears first during continuous operation?

The motor draws 0.16 A at 12 V, so the thermal limit of the sleeve bearing is reached before the airflow of 7.97 CFM drops.

What noise and heat should I expect when this fan runs all day at 6600 RPM?

It produces 31 dBA and moves 7.97 CFM while drawing 0.16 A from a 12 V supply.
