Compact 40 mm cooling fan

This UTEK case fan measures 40x40x20 mm and runs on 12 V DC through a three-pin connector. It draws 1.38 W while spinning at 8200 RPM to deliver 10.8 CFM of airflow. The unit is suited to tight spaces such as 1U power-supply enclosures or small-form-factor chassis where larger fans cannot fit.

Three-pin voltage control limits

The fan uses a simple three-pin interface that relies on motherboard voltage regulation rather than PWM signalling. Speed can only be adjusted within the 4 V to 13 V supply range provided by the header. Systems without voltage-controlled fan headers will run the fan at full 12 V speed continuously, producing the rated 29.5 dBA noise level.

8200 RPM airflow decides fit

At 8200 RPM the fan moves 10.8 CFM, a figure that determines whether it can cool a given component in the available space. Builds needing higher static pressure or lower acoustic output will find this specification insufficient. Buyers who need greater airflow or quieter operation at the same 40 mm footprint should look for a model with different performance ratings.

Questions about this item

Which voltage range should I pick for my 1U power supply?

The fan runs from 4V to 13V, so it works with a standard 12V rail in a 1U PSU.

What does 8200RPM mean for airflow in a tight chassis?

At 8200RPM the fan moves 10.8CFM, enough to push air through a dense 1U power supply.

How does the 3-pin connector limit speed control?

The 3-pin header gives voltage control only; PWM is not supported, so speed varies with the supplied voltage.
