40 mm 12 V dual-ball case fan

Ideal for compact builds needing focused airflow

Builders who need higher static pressure for dense radiators should look elsewhere. Systems requiring PWM speed control or larger frame sizes are not suited to this model.

Questions about this item

What are the exact mounting hole dimensions for the 40x40x20mm frame?

The fan uses a standard 40mm square frame with mounting holes spaced for 40mm centres, matching typical 4020 chassis cut-outs.

How do I connect the 12V .60A power leads without reversing polarity?

Connect the red wire to +12V and the black wire to ground; the 0.60A draw requires a header rated for at least 1A to avoid voltage drop.
