Compact 40 mm 12 V PWM fan for tight server builds

This 40 mm case fan runs on 12 V and spins at 25000 RPM, moving 32.9 CFM of air through a 40 by 40 by 28 mm frame. Double ball bearings support the high rotational speed, while a four-wire lead provides PWM control and speed reporting. It suits compact servers and industrial enclosures where space is limited but airflow must remain strong.

Noise and power limits of the 12 V PWM interface

At full speed the fan produces 64 dBA, a level that may be intrusive in quiet workspaces or home offices. The 2.10 A current draw demands a fan header or controller rated for at least that amperage on the 12 V rail. Builders who need silent operation or who have only low-current headers should consider alternative cooling approaches.

Questions about this item

Should I pick this 40 mm fan or a different size for my build?

Choose the 40 mm model only if your chassis or heatsink has 40 mm mounting holes; larger fans will not fit that footprint.

What does the 32.9 CFM airflow mean once the fan is installed?

At 25000 RPM the fan moves 32.9 CFM of air through a 40×40×28 mm frame, delivering strong spot cooling at 64 dBA noise.
