Manufacturer description

The WINSINN 40mm fan 12V 2-pack covers small cooling jobs where a larger fan won't fit. Each 4010 fan measures 40mm x 40mm x 10mm. It suits a 3D printer extruder, hotend or nozzle shroud, and also works for venting a small PC case, router, Raspberry Pi enclosure or TV box. Each brushless fan runs on 12V DC at 0.1A and 1.2W. It spins at 6500 RPM and moves 7.1 CFM at 3.92 mmH2O of static pressure, with a rated noise level of 28.2 dBA. Dual ball bearings are rated for 50,000 hours, so the fan can run 24 hours a day in an always-on printer or home server. WINSINN backs the fans with a 5-year…

Frequently Asked Questions

Will this fan work on a 24V 3D printer?

Not directly. The fan is rated for 12V DC at 0.1A. On a 24V mainboard you need a 24V fan or a step-down converter that supplies 12V. Check your printer's fan output voltage before you install it.

What connector does the WINSINN 40mm fan use?

Each fan has a 2-pin XH2.54 connector on a 300mm (11.8in) cable. Many 3D printer boards use this style of plug. A standard 3-pin PC motherboard fan header uses a different housing, so you may need an adapter.

Can I control the fan speed with PWM?

No. It is a 2-wire fan with no PWM or tach wire. You can only change the speed by changing the supply voltage. At the full 12V rating it spins at 6500 RPM and moves 7.1 CFM.

How loud is this 4010 fan?

WINSINN rates it at 28.2 dBA at full 12V speed. That is quiet enough for a printer enclosure or network closet, but you may hear it in a silent desktop build.

What warranty and lifespan does the fan have?

WINSINN lists a 5-year warranty and a 50,000-hour rated life from the dual ball bearings, which suits long 24/7 runs. Check the product listing for the current warranty claim process.
