Compact blower for tight builds
This 40 mm blower fits the 40x40x10 mm footprint and runs on 5 V at 0.25 A. The three-wire connection provides speed feedback for monitoring. It targets system integrators and hobbyists who need directed airflow in confined enclosures.
4010 form factor limits heat load
The small frame and 5 V supply restrict the volume of air the fan can move, so it handles low-power components and spot cooling. It runs out of headroom when tasked with high-wattage CPUs or multi-GPU configurations that demand greater static pressure.

Questions about this item
Will this 4010 blower fan fit alongside the 40 mm fans I already have?
Yes, it shares the 40 x 40 x 10 mm footprint so it mounts in the same cut-outs as other 4010 fans.
How can I confirm the blower is running correctly after I connect the three-wire lead?
The third wire reports speed; check your BIOS or fan-control software for an RPM reading that matches the 5 V, 0.25 A rating.
