Compact 50 mm Case Fan for Tight Builds

This 50 x 50 x 15 mm axial fan fits small-form-factor cases and tight clearance spots where larger fans cannot mount. It draws 0.145 A at 12 V for 1.74 W of power and spins at 7000 rpm to move 18.6 cfm of air. The two-pin connector provides simple voltage-controlled operation.

Two-Pin Voltage Control Limits

The 2-pin DC connector means speed varies only with supply voltage between 12 V and 7 V; there is no PWM signal for precise duty-cycle control. At full voltage the fan produces 40 dB of noise and 0.26 inch-H₂O of static pressure. Builders who need quieter low-speed operation or motherboard fan-curve management will not get those features from this interface.

Check Mounting Holes and Header Type

Verify that your chassis has 50 mm mounting holes with 15 mm depth clearance for the frame. Confirm the motherboard or fan controller offers a 12 V two-pin header; a four-pin PWM header will run the fan at fixed maximum speed without speed reporting. The magnetic levitation bearing and PBT frame are rated for continuous operation within the stated voltage range.

Questions about this item

Should I pick the 2-pin version or look for a 3-pin or 4-pin model instead?

This fan uses a 2-pin connector, so it runs at full 7000 rpm whenever the 12 V rail is powered; there is no PWM or voltage-control wire to vary the speed automatically.

What does the 18.6 CFM airflow rating actually deliver inside a typical case?

At 7000 rpm the fan moves 18.6 CFM with 0.26 inch-H₂O static pressure, enough for spot-cooling small enclosures or tight component clearances but not for high-restriction radiators.

How does the 2-pin DC interface limit speed control in practice?

The 2-pin design only accepts a steady DC voltage; reducing the supply toward 7 V will lower the speed and noise, but the motherboard cannot send PWM signals or read a tachometer signal.
