120 mm server cooling fan

The TOPLAB SNOW FAN YY12025H24B is a 120 mm square frame fan designed for server and equipment cooling. It operates on a 24 V DC supply and draws 0.25 A. The three-wire connection provides power and a tachometer signal for speed monitoring.

24 V DC power constraint

The fan requires a 24 V DC source and cannot run directly from common 12 V or 5 V rails. The 0.25 A current draw must be supported by the power supply or controller. The three-wire interface does not accept PWM speed control, so voltage regulation is the only way to vary fan speed.

Questions about this item

What does the 24 V rating mean for installation?

The fan requires a 24 V DC power source and draws 0.25 A, so the supply or header must provide at least that voltage and current.

How does the 120x120x25 mm size affect fitment?

It matches the standard 120 mm square frame with 25 mm thickness, fitting common server and chassis mounts that use that footprint.
