About this item
Small fans fail quietly, and a 40mm 12V cooling fan 4 pack keeps spares on hand for the next one. These 4010 fans measure 40x40x10mm, run on DC 12V and use a 2 pin connection, which suits 3D printer hotend and board cooling, small PC case vents, network boxes and DIY electronics projects.
Will a 40mm 4010 12V fan work on my 3D printer?
It can, if your printer's fan header supplies 12V. Some printers use 24V fans, so check your mainboard or old fan label before plugging in.
- 2 pin means no speed sensing: motherboards can't report RPM, though voltage control may still work.
- Connector type: compare the plug in the photos with your header; you may need to swap or splice.
- Airflow and noise: not in the title, so check the description if quiet operation matters.
