Compact 40 mm maglev fan

This 40x40x20 mm case fan uses a maglev bearing and runs on 12 V power. It draws 1.38 W and suits small-form-factor builds or tight clearance spots. The tach output lets the system monitor speed without extra wiring.

Thermals noise and power

At 1.38 W draw the fan adds minimal heat to the loop. Maglev operation keeps mechanical noise low during normal use. The slim 20 mm profile fits cramped chassis without blocking adjacent components.

Questions about this item

How do I install the 40×40×20 mm Maglev fan and what step is often missed?

Mount the fan using the four 40 mm corner holes with 3 mm screws, orient airflow toward the heatsink, then connect the three-pin tach connector to the motherboard header; the step most people miss is plugging in the tach wire so the BIOS can monitor speed.

What maintenance will the MB40201VX-D070-G99 need later?

The magnetic-levitation bearing eliminates oil replenishment; simply blow dust from the blades and frame with compressed air every 6–12 months and verify the tach signal still reports RPM in the BIOS.
