Compact 40 mm Case Fan

The Zyvpee AFB0412LB is a 40 mm square case fan measuring 40 by 40 by 15 mm. It runs on 12 V DC and draws 0.09 A through a standard three-pin power connector. Ball-bearing construction supports continuous DC cooling in tight chassis spaces.

Suited for Small-Form-Factor Builds

This fan fits mini-ITX cases, 1U server trays and embedded boards that only accept a 40 mm mounting pattern. The three-pin header provides tachometer feedback for BIOS speed monitoring. Buyers who need higher airflow, larger frame sizes or PWM control should look at other models.

5000 RPM Speed Decides Fit

At 5000 RPM the fan delivers 6.5 CFM at 18.5 dBA, a balance fixed by its frame size and bearing choice. That single speed rating determines whether the airflow meets the thermal target of the target device. No other specification overrides this limit.

Questions about this item

How do I install the 40 mm AFB0412LB fan and connect its 3-pin TAC connector?

Mount the fan using the four screw holes on the 40x40 mm frame, orient the airflow arrow toward the heatsink, then plug the 3-pin connector into a 12 V fan header; the third wire carries the tachometer signal so the motherboard can report 5000 RPM speed.

What maintenance will the ball-bearing AFB0412LB need over time?

The dual ball bearing is sealed for life; no lubrication is required, but dust buildup on the blades reduces the 6.5 CFM airflow, so clean the fan with compressed air every few months.

At what point does the 18.5 dBA noise level become the limiting factor during sustained loads?

At the fixed 5000 RPM the fan always produces 18.5 dBA; if that acoustic level is too high for your environment, it becomes the practical limit before thermal throttling occurs.
