SUNON 50 mm 24 V case fan

The SUNON KDE2405PFB1-8 is a 50 mm square frame fan that runs on 24 V DC and draws 1.0 W. Double ball bearings support a speed range of 5000 to 5499 RPM and deliver 10 to 15 CFM of airflow at 20 to 25 dBA. The 2-pin connector provides power only with no speed signal or control wire.

Who this suits and who should look elsewhere

Builders who need a compact 24 V fan for tight 50 mm x 50 mm x 10 mm spaces will find the dimensions match. The 2-pin lead works with constant-voltage headers but offers no PWM or tachometer feedback. Systems that lack a 24 V fan supply or require speed monitoring and variable control should look elsewhere.

The specification that decides fit

The 24 V DC rating is the single figure that determines whether this fan can be powered directly by the available header. If the board or controller only provides a different voltage the fan will not operate correctly.

Questions about this item

How long will the double ball bearing last at the rated 5000-5499 RPM?

The double ball bearing is rated for continuous operation at 5000-5499 RPM, providing a longer service life than sleeve bearings under sustained high-speed use.

What noise and heat output should I expect when running this fan at 24 V all day?

At 24 V the fan draws 1.0 W and produces 20-25 dBA of noise, with minimal heat added to the chassis.

Does the 2-pin connector plug straight into a standard 24 V fan header on my board?

Yes, the 2-wire 2-pin lead is designed for a 24 V DC fan header; no PWM control or extra adapter is required.
