12 cm 48 V 4-wire case fan

This 12 cm case fan runs on a 48 V DC supply and draws 1.3 A through a 4-wire connection. It is built for systems that provide a 48 V fan header and need high airflow from a standard 120 mm frame.

Suited for enclosures with 48 V fan power

Builders whose chassis or controller only offers 12 V fan power cannot use this model. Systems limited to 3-pin voltage regulation will not support the 4-wire interface.
