80 mm 24 V inverter cooling fan

This 80 mm by 80 mm by 38 mm fan runs on 24 V at 0.44 A and draws 10 W. It spins at 4900 RPM and moves 53.7 CFM at 91.1 Pa static pressure. The two-ball bearing is rated for 30000 hours of operation. It is built for graphics-card cooling where a compact high-pressure airflow is required.

Replaces lower-pressure 70 mm or 80 mm fans

The 53.7 CFM and 91.1 Pa rating make the jump worthwhile when the existing cooler cannot push enough air through a dense heatsink. The 45 dBA noise level at full speed is the trade-off for that pressure gain. Buyers who need quieter operation at the same airflow should look elsewhere.

Check 24 V supply and 80 mm mounting

Verify that the graphics card or controller provides a 24 V 0.44 A header before ordering. The frame measures 80 mm by 80 mm with a 38 mm thickness, so confirm clearance around the heatsink and any shroud. The two-ball bearing and 30000-hour rating suit continuous duty, but the 45 dBA output may be intrusive in silent builds.

Questions about this item

What are the exact mounting-hole dimensions for the 80 × 80 mm frame?

The fan measures 80 mm by 80 mm with a 38 mm thickness; mounting holes follow the standard 80 mm square pattern.

How do I connect the 24 V 0.44 A power leads without damaging the inverter board?

Apply 24 V DC only, observing the red-positive and black-negative wires; the two-ball bearing motor draws 0.44 A at full speed.

When should I plan to replace the two-ball bearing assembly rated for 30000 hours?

Expect roughly 30000 hours of continuous operation before bearing wear increases noise above the rated 45 dBA level.
