Sunon KD2404PFB3 24 V Server Fan

This new 40 x 40 x 10 mm square fan runs on 24 V DC and draws 0.9 W. It uses a three-wire connection and carries the B4504.AR.GN.I21 identifier. The unit is designed for server and compact chassis cooling where a 24 V supply is available.

Ideal for 24 V server builds

Builders with a 24 V fan header and a 40 mm mounting pattern can use this fan directly. It is not suited to systems that lack a 24 V header, that require a larger mounting footprint, or that need four-wire PWM control.

Questions about this item

What voltage power supply do I need for this 24 V fan?

The fan runs on a 24 V DC source, so your system must provide a 24 V rail or a compatible 24 V power adapter.

Will the 3-wire connector plug into a standard 4-pin PWM header on my motherboard?

Yes, the 3-wire plug fits a 4-pin PWM header; the fourth pin is left unused and the fan will run at full speed without PWM control.
