About this item
Small 40mm 12V fans like these are common in 3D printer hotends, mini PCs, network boxes and DIY electronics. This 4-pack of 4010 (40x40x10mm) fans is listed new for $9.89. According to the title, they run on DC12V and use a 2-pin connector.
Will a 40mm 12V 2-pin fan work in my device?
Check three things: your device supplies 12V to the fan, there's room for a 40x40x10mm frame, and the 2-pin plug matches the header.
- Voltage: Many printers and boards use 24V or 5V fans, so check before you swap.
- Speed reporting: 2-pin fans don't report their speed. That's fine for most printer and case uses.
- Spares: With four fans, you'll have extras for future repairs.
- Safety net: Covered by the eBay Money Back Guarantee.
A practical pack of spares for makers and tinkerers.
