40 mm alarm fan for tight spaces
The Fans EFB0412MD-ROO is a 40×40×20 mm case fan that runs on 12 V and draws 0.10 A. Its three-wire connector supplies power and an alarm signal so the system can detect a stalled rotor. The compact frame suits small-form-factor chassis or equipment racks where full-size fans cannot fit.
Three-wire alarm signal simplifies monitoring
The alarm lead reports fan health directly to a motherboard or fan controller without extra sensors. Builders who need variable-speed control should note this model lacks a PWM wire. Units requiring higher airflow or larger mounting holes will need a different fan size.

Questions about this item
Will the 12 V 0.10 A motor hold steady under continuous load?
The 12 V 0.10 A rating is the continuous operating point; the motor is designed to sustain that draw without thermal shutdown.
How loud is the 40x40x20 mm fan after hours of operation?
The 40 mm by 40 mm by 20 mm frame moves air at the rated 0.10 A; expect a low hum typical for this form factor.
