80mm 12V 4-pin case fan

The SXDOOL AUC0812D is an 80mm case fan built for 12V systems with a 4-pin PWM connector. It uses a dual ball bearing and spins between 1000 and 4500 RPM with a tolerance of ±10%. The black, non-LED frame measures 80 by 80 by 25mm and draws 0.70A. A 110mm cable reaches the motherboard header.

Compact builds with PWM control

This fan suits small-form-factor chassis or replacement spots that only accept an 80mm frame and require 4-pin speed regulation. The dual ball bearing supports continuous operation at higher RPM. Builders who need a 3-pin voltage-controlled header or a larger frame for higher static pressure should look at other options.

46 CFM airflow at 40 dBA

The fan delivers 46 CFM of air volume at a rated noise level of 40 dBA. This single figure determines whether the cooling performance matches the thermal load of your specific component or enclosure.

Questions about this item

Should I choose this 80mm 12V 0.70A 4-pin fan or a different size for my case?

This model fits 80mm mounting holes and draws 0.70A at 12V, so select it only if your chassis has 80mm slots and your motherboard header can supply that current.

What does the 4500 RPM top speed mean for actual cooling?

At 4500 RPM the fan moves up to 46 CFM of air while producing 40 dBA, giving strong airflow for tight spaces but audible noise under full load.

How does the 4-pin PWM connector control the fan in practice?

The 4-pin header lets the motherboard vary speed between 1000 and 4500 RPM using PWM, so the fan runs quietly at idle and ramps up only when temperatures rise.
