40×40×28 mm 12 V case fan

This 40 mm square frame fan is 28 mm thick and runs on 12 V at 0.8 A for 9.6 W. It uses a double ball bearing and ships with a 4 cm cable ending in a standard fan interface. The supplier lists it for medical, rail, industrial and vehicle cooling applications.

Builders needing a compact 12 V axial fan

Suits tight enclosures that accept a 40×40×28 mm footprint and a 4 cm lead. Not for systems requiring PWM speed control, larger airflow volumes, or longer cable reaches. Buyers who need a different voltage, bearing type or mounting pattern should look elsewhere.

Check voltage, mounting holes and header

Verify the board or controller supplies 12 V and can deliver 0.8 A on the fan header. Confirm the chassis has 40 mm mounting centres and enough clearance for the 28 mm depth. Ensure the 4 cm cable can reach the header without extension.

Questions about this item

What fan header voltage must my motherboard provide for this 12V fan?

The fan requires a standard 12V fan header; the motherboard must supply 12V to match the fan's rated voltage.

Can I run this double ball bearing fan on a 5V header to reduce noise with older components?

No, the fan is rated for 12V operation at 0.8A; running it from a 5V header would not provide the correct voltage.

How can I verify the fan is spinning correctly after connecting the 4cm cable?

Check that the fan spins smoothly and listen for steady airflow; the double ball bearing should run without grinding or rattling.
