Zyvpee 40 mm Inverter Fan

The Zyvpee GM2404PQB1-8A is a 40 mm by 28 mm case fan that runs on 24 V and draws 3.9 W through a two-pin connector. Its ball bearing and inverter cooling design target compact CPU coolers and tight chassis spaces where a low-profile frame is required.

Suits 24 V two-pin headers only

Builders with a 24 V two-pin header on a small-form-factor board or specialised cooler can use this fan directly. It is not for systems that lack a 24 V two-pin supply, nor for users who want addressable lighting or PWM speed control.

Deciding spec: 24 V two-pin power

The single specification that decides fitment is the 24 V two-pin power requirement; the cooler or motherboard must provide exactly that voltage and connector type for the fan to operate.

Questions about this item

How much airflow does the 3.9 W rating actually deliver inside a case?

At 3.9 W and 24 V the fan is designed for inverter cooling on a CPU cooler, so it moves enough air for that focused spot-cooling role.

What does the 2-pin connector limit for speed control?

The 2-pin power connector provides fixed 24 V supply, so the fan runs at full speed whenever it is powered.

Will the 40 mm by 28 mm frame fit a standard 40 mm fan mount?

Yes, the 40 mm square footprint matches common 40 mm mounting holes, and the 28 mm thickness fits most slim-fan clearances.
