Compact 40 mm DC fan for server cooling

This 40 mm square fan runs on 12 V DC and draws 0.08 A. The 10 mm thick frame fits tight server and appliance bays. It is built for continuous airflow in rack-mounted equipment.

Two-wire connection and slim profile

The 2-wire lead provides simple power without speed reporting or PWM control. At 10 mm depth it slots into narrow chassis walls where larger fans cannot mount. Buyers needing tachometer feedback or variable speed should choose a three- or four-wire model.
