Compact 50 mm server fan

The GAMMA26 D05F-12BS2 is a 50 by 50 by 25 millimetre square fan built for tight server and workstation chassis. It runs on 12 volt DC power and draws 0.15 amperes through a three-wire connection. The 26 millimetre frame depth fits restricted bays where standard 25 millimetre fans cannot mount.

Replaces larger 50 mm units

This fan suits builds that need the 50 millimetre footprint but cannot accommodate thicker frames or higher current draw. It is not for systems that require PWM speed control or higher airflow ratings than the 0.15 ampere design provides.

Questions about this item

What mounting-hole spacing does the 50 mm square frame use?

The 50 mm square frame follows the standard 50 mm mounting pattern, so four screws on 50 mm centres secure it to any compatible case or server chassis.

Which wire on the 3-wire connector carries the tachometer signal?

The third wire (usually yellow) provides the RPM tachometer signal; connect it to a motherboard or fan-controller header that reads fan speed.
