Compact 40mm 12V case fan

The SXDOOL MGT4012LR-A10 is a 40mm square frame fan built for tight spaces inside small-form-factor systems. It runs on 12V and draws 0.08A, making it a direct replacement for the original cooler in Acer EL1600 motherboards and similar OEM boards. The three-pin connector supplies power and a tachometer signal to the motherboard header. No LEDs are fitted, so the unit stays visually neutral in any build.

Hydro bearing sustains airflow

A hydro-dynamic bearing supports the rotor shaft, reducing friction during continuous operation compared with sleeve designs. At a rated 0.96W the motor delivers steady rotation for northbridge, southbridge or VRM zone cooling without the speed decay that can appear in short-spec sleeve units. The 4010 form factor (40mm by 10mm thick) fits the mounting holes and clearance envelope specified for the target OEM chassis.

Low power keeps thermals quiet

With only 0.96W motor power the fan adds minimal heat to the case interior and draws little current from the 12V rail. The hydro bearing runs quietly at typical speeds, avoiding the whine or rattle that can develop in lower-quality bearings over time. Black plastic frame and blades blend into dark chassis interiors while the non-LED design eliminates light bleed in media-server or bedroom PCs.

Questions about this item

How much noise and heat does the 0.96 W motor produce when running all day?

The 12 V, 0.08 A motor draws only 0.96 W, so heat output is minimal and the hydro bearing keeps noise low during continuous use.

What connector must my motherboard or power supply provide for this 3-pin fan?

You need a standard 3-pin fan header supplying 12 V; the fan uses a 3-wire, 3-pin connector with no LED or PWM wiring.

Will the 40 mm frame fit the Acer EL1600 chassis and clear nearby components?

The fan measures 40×40×10 mm and is specified for the Acer EL1600 motherboard and similar north/south bridge cooling spots.
