Replacement 35 mm Turbo Blower

The SXDOOL AB3505MX-QB0 is a 35 mm square DC blower designed to replace a worn notebook fan. It runs on 5 V at 0.14 A and draws 0.7 W while spinning at 12800 RPM. The two-wire red and black connector supplies power directly.

5 V Two-Wire Power Constraint

Operation is limited to a 5 V DC source capable of delivering 0.14 A through a simple two-pin header. Speed is fixed at 12800 RPM with no PWM or voltage regulation built in. The 35 mm by 7 mm frame fits only bays that match those exact dimensions.

Upgrade From Failed OEM Fan

This unit replaces an original blower that has become noisy or seized after extended use. The ADDA special bearing rates 60000 hours of service life at up to 70 °C. The jump is worth it when the existing fan no longer moves 4.4 m/s airflow at 26.2 dBA.
