80mm 24V Fan for Server Cooling

The OEM Industries AFB0824SH is an 80mm frame fan designed for 24V DC systems. It draws 0.33A and spins at 4000rpm to deliver 46.62CFM of airflow. The three-wire connector provides tachometer feedback for speed monitoring. It suits rackmount chassis or industrial enclosures that require a compact, high-speed air mover.

Sustained Load Behaviour

A sleeve bearing supports the rotor during continuous operation at 4000rpm. The bearing type maintains consistent rotational speed without the wear pattern associated with ball bearings under constant load. Acoustic output remains at 40dBA when the fan runs at full rated voltage. The 24V supply ensures stable current delivery during extended duty cycles.

3-Wire Interface Limits

The three-wire connection supplies power, ground and a speed signal but lacks PWM control. Fan speed is therefore fixed by the applied voltage rather than a duty-cycle command. Motherboard headers that expect a four-wire PWM fan will not regulate this unit automatically. Builders needing variable speed must implement external voltage regulation or select a four-wire alternative.

Questions about this item

How loud and hot does the AFB0824SH get when running at 4000 rpm all day?

At full speed the fan produces 40 dBA and moves 46.62 CFM while drawing 0.33 A at 24 V.

What power connector must my motherboard or controller provide for the 3-wire AFB0824SH?

The fan uses a standard three-wire connector that supplies 24 V, ground and a tachometer signal.

Will the 80 mm AFB0824SH fit the mounting holes on my older 8025-frame heatsink?

Yes, the 80 mm frame matches the 8025 form factor used on many legacy coolers.
