Delta 80 mm 12 V case fan
The Delta AFB0812VH is an 80 mm axial fan designed for chassis and power-supply cooling. It runs on 12 V and draws 0.41 A, making it suitable for standard motherboard or controller headers. The double-ball bearing and 4000 RPM speed target systems that need reliable forced-air exchange in a compact slot.
Double ball bearing and 4.92 W power draw
The double ball bearing reduces wear compared with sleeve designs, supporting continuous operation in tight spaces. At 4.92 W the fan adds minimal load to a 12 V rail while delivering 5.2 m/s wind speed and 50 CFM airflow. The 0.66 mmH2O static pressure helps push air through restrictive grilles or heat-exchanger fins.
35 dBA noise at 4000 RPM ± 10%
At the rated speed the fan produces 35 dBA, which is audible in quiet rooms but typical for high-flow 80 mm units. The 80*80*25 mm frame fits standard mounting holes, yet the 50 CFM ceiling means it cannot satisfy high-density builds that demand significantly more airflow. Builders needing greater volume or lower noise should consider larger-frame alternatives.

Questions about this item
How often will the double ball bearing in this 80 mm fan need replacement?
Double ball bearings typically last longer than sleeve types; expect several years of continuous 4000 RPM operation before wear becomes noticeable.
What limit appears first when this fan runs at 4000 RPM for hours?
The 4.92 W power draw and 35 dBA noise level remain steady; thermal throttling is unlikely because the motor is rated for sustained 12 V 0.41 A load.
How much noise and heat does this 8025 model produce during all-day use?
It emits 35 dBA and moves 50 CFM at 5.2 m/s; the 4.92 W draw adds minimal heat to the chassis while maintaining 0.66 mmH₂O pressure.
