Compact 40 mm ball-bearing fan

The Zyvpee GM2404PQB1-8A is a 40 by 28 millimetre case fan that runs on 24 volts and draws 2.9 watts. It uses a three-wire power connector and a ball bearing for continuous operation in tight chassis spaces. The black, non-LED frame keeps the appearance neutral.

Fits 24 V three-wire headers only

Builds that supply a 24 volt three-wire header can use this fan directly. Systems that provide only a different voltage or a two-wire or four-wire header cannot connect it without an adapter or a voltage change.

24 V 2.9 W three-wire specification

The single deciding specification is the 24 volt 2.9 watt three-wire electrical interface. If the chassis or controller does not match that exact combination, the fan will not operate as intended.

Questions about this item

What does the 2.9W rating mean once the fan is running in my system?

At 24V the fan draws 2.9W, so it adds only a small load to the power supply while delivering 40×28mm airflow.

How does the three-wire connection affect speed control?

The three-wire lead provides power, ground and a tachometer signal; it supports RPM monitoring but not PWM speed control.

Will the 40×28mm frame fit my case's 40mm mounting holes?

Yes, the 40mm square frame matches standard 40mm mounting points and the 28mm thickness clears most chassis walls.
