40 mm 12 V Case Fan for Tight Spaces

This 4010 fan measures 40 by 40 by 10 millimetres and draws 0.8 watts at 12 volts with a 0.06 amp current. It connects through a standard three-pin header and includes velocimetry support for speed monitoring. The compact frame suits small-form-factor builds, rack appliances or GPU coolers where larger fans cannot fit.

Three-Pin Speed Control Limits

The three-pin interface provides voltage-based speed regulation rather than pulse-width modulation, so minimum speed and fine granularity depend on the motherboard or controller capability. Velocimetry feedback allows RPM monitoring but does not enable closed-loop control without a compatible header. Builders needing precise low-RPM curves or four-pin PWM control should verify their board supports voltage regulation for this fan.

Questions about this item

Should I pick the 40 mm 12 V 0.8 W 3-pin 4010 or another version?

This listing is for the single 4010 model at 12 V, 0.8 W and 0.06 A; no other versions or capacities are offered.

What does the 0.8 W rating mean once the fan is installed?

It draws 0.06 A from a 12 V header, so the motherboard only needs to supply a modest 0.8 W for the 40 mm frame.
