Compact 80 mm case fan for temperature-controlled

The SXDOOL AUB0812HHD is an 80 by 80 by 20 millimetre case fan that runs on 12 volts and draws 0.40 amps. Its four-pin connector enables temperature-controlled speed regulation so airflow matches system heat output. The unit suits builds that need a slim 80 mm footprint with automatic fan-curve response.

Steady airflow under continuous thermal load

Because speed is governed by the four-pin temperature signal, the fan ramps up as component temperatures rise and holds the higher RPM for as long as the load persists. This behaviour maintains consistent airflow during extended gaming or rendering sessions rather than spiking only for short bursts. The 0.40 amp draw remains stable throughout prolonged operation.

Questions about this item

How loud does the AUB0812HHD get when it runs at full speed all day?

The fan uses a 4-pin temperature-controlled design, so its speed and noise level vary with system temperature rather than running at a fixed maximum.

What connector must my motherboard or fan controller provide for this 80 mm fan?

It requires a standard 4-pin PWM header to enable the temperature-controlled speed regulation.
