  • Low noise at 35.2 DBA keeps systems quiet
  • 50,000 hour service life ensures long reliability
  • 12V 0.30A input draws only 3.6W power
  • Operates from -25 to 75 degrees Celsius environments

80 mm axial fan for industrial cooling

The AD0812UB-A70GL is an 80 mm by 25 mm axial fan built by Taiwan ADDA for 12 V DC systems. It draws 0.30 A and spins at 3400 RPM to deliver 46.13 CFM of airflow at 5.11 mmAq static pressure. Noise is rated at 35.2 dBA and the bearing is rated for 50,000 hours across a -25 °C to 75 °C range.

Replaces 80 mm fans below 40 CFM or 4 mmAq

Swapping in this unit makes sense when the existing 80 mm fan cannot move enough air through a restrictive heatsink or filter. The 3.6 W motor provides a measurable jump in pressure and volume without changing the mounting pattern or voltage rail.

Verify 12 V DC header and 80 mm mounting holes

Confirm the target device supplies 12 V DC on a two-wire or three-wire header and that the chassis has standard 80 mm screw centres. The fan operates continuously between -25 °C and 75 °C, so ensure the enclosure ambient stays within that window.

Questions about this item

Will the 80 mm by 80 mm by 25 mm frame fit my standard 80 mm fan mount?

The fan measures 80 mm by 80 mm by 25 mm, matching the common 80 mm square mounting pattern used in many chassis.

How do I connect the 12 V 0.30 A power leads without damaging the fan?

Connect the two DC leads to a 12 V source rated for at least 0.30 A, observing the marked polarity; reversing the wires can stall the motor.

When should I plan to replace a fan rated for 50,000 hours of service life?

At continuous operation the 50,000 hour rating equals roughly 5.7 years; replace it if noise rises above 35.2 dBA or airflow drops below 46.13 CFM.
