Compact 40 mm cooling fan

The SXDOOL MF40102VX-1Q03C-A99 is a 40 mm square fan designed for 24 V operation in tight spaces. It draws 1.92 W and spins at roughly 10000 RPM with a stated noise level of 36.8 dBA.

Suited for 3D printer hot-ends and small enclosures

This unit fits extruder cooling on machines such as the BLV Mgn Cube or Ender where a 4010 form factor is required. It is not for builders who need a larger frame size, higher static pressure at lower voltage, or a different mounting pattern.

Handles focused airflow in confined areas

The 40 mm by 10 mm profile delivers targeted cooling for hot-end assemblies and similar compact electronics. Headroom diminishes when the application demands greater air volume or a wider mounting footprint than the 4010 standard allows.

Questions about this item

Will this 24 V MF40102VX-1Q03C-A99 run directly from my printer's 24 V fan header?

Yes, the fan is rated for 24 V and draws 1.92 W, so it connects straight to a 24 V fan header on the printer board.

Can I keep using my existing 40 mm mounting holes with this Sunon magnetic-bearing 4010 replacement?

The frame measures 40 × 40 × 10 mm, matching the standard 4010 footprint, so your current mounting holes line up without modification.

How do I confirm the fan is spinning at the specified speed after installation?

At full voltage the fan should reach 10000 RPM ±10 % and produce about 36.8 dBA; check the printer's fan-speed readout or listen for the steady high-pitched airflow tone.
