Compact High-Speed Cooling

The SXDOOL 140E is a 40mm case fan built with dual ball bearings for continuous high-RPM operation. It runs on 12V at 0.90A and spins at 18000 RPM to move a large volume of air through tight spaces. The black frame measures 40 by 40 by 28mm and carries no lighting.

Specialised High-Airflow Scenarios

This fan suits builders who need maximum airflow from a 40mm slot and can tolerate significant noise. It is not for standard desktop builds, quiet workstations, or any system where acoustic comfort matters. The supplier notes the unit is a special high-speed model not intended for ordinary computers.

Connector and Speed Verification

The fan connects via a 4-wire 2510-4 pin 5-hole interface that must match the header on your board or controller. Confirm the pin layout and voltage control method before purchase, as the 18000 RPM speed and 72.00 dBA noise level are fixed characteristics of this model.
