Zyvpee AFB1224HHE -R00 24V 0.45A 120mm 38mm 3 Pin Case Fan

Delta 12CM 12038 Inverter Fan

The Zyvpee AFB1224HHE-R00 is a 120mm by 38mm case fan designed for 24V DC systems. It uses a dual ball bearing and a three-pin power connector. This unit suits industrial chassis, inverter enclosures or server builds that require high static pressure from a 12038 form factor.

24V Three-Pin Power Limits

The fan draws 0.45A at 24V and connects via a standard three-pin header. Speed control depends on the host varying the supply voltage because no PWM wire is present. Tachometer feedback is provided on the third pin for monitoring. Builders using 12V headers must add a step-down converter or the fan will not spin.

Pre-Install Checks

Verify that your chassis accepts a 38mm thick 120mm frame and that the mounting holes align with 120mm spacing. Confirm the power source delivers 24V DC and the header supplies at least 0.45A. Ensure the three-pin plug pinout matches your board because some vendors swap sense and ground positions.
