Compact 40mm Fan for Tight Builds

This 40mm square fan fits small-form-factor cases and legacy CPU coolers where larger units cannot be mounted. It targets system integrators and hobbyists who need a direct 12V replacement for noisy or failed original equipment.

Low-Profile Frame with Standard 3-Pin Lead

The 10mm-thick black frame uses a three-wire 3-pin connector that plugs straight into most motherboard headers without adapters. No LED lighting keeps the unit visually neutral inside windowed or closed chassis.

12V 0.11A Draw Defines Header Compatibility

Rated at 12 volts and 0.11 amps, the motor stays within typical 1A fan-header limits so it will not trip protection circuits. Builders needing higher airflow or PWM speed control should look elsewhere.

Questions about this item

What does the 3-pin connector limit for speed control?

The 3-pin connector supplies 12V power and a tachometer signal; it does not carry a PWM line so the motherboard can only adjust speed by varying voltage.

What clearance does the 40mm square frame need?

The fan measures 40mm by 40mm with a 10mm thickness, so the mounting surface must provide at least that footprint and depth.

How do I orient the three wires when plugging it in?

Align the keyed 3-pin plug with the motherboard header — ground, 12V, and tach pins match the connector shape so it only fits one way.
