40 mm Fan for Gateway SX Desktops

The OEM Industries MGT4012LR-A10 is a 40 mm ball-bearing fan designed as a direct replacement for Gateway SX2110G, SX2110 and SX2185 systems. It runs on 12 V at 0.08 A and connects via a standard three-pin header. The black plastic frame measures 40 by 40 by 10 mm and has no LED lighting.

Who This Suits

This cooler fits owners of the listed Gateway models who need a quiet, low-profile fan to keep a small-form-factor CPU within thermal limits. It is not for builders who need a larger heatsink assembly, higher airflow, PWM speed control or RGB illumination.

3-Pin 12 V Power Connector

The fan draws 0.08 A from a three-pin 12 V header, so the motherboard must supply that exact voltage and connector type. Verify the header pin-out and clearance before purchase.

Questions about this item

Does my motherboard need a 3-pin fan header to run this 40mm cooler?

Yes, the cooler uses a 3-pin power connector that plugs directly into a standard motherboard fan header.

Will this 10mm thick fan fit inside my Gateway SX2110 or SX2185 chassis?

The 40x40x10mm dimensions match the original cooler used in those Gateway small-form-factor systems.

How can I confirm the ball-bearing fan is spinning correctly after installation?

Connect the 3-pin header, power on the system, and verify the fan rotates smoothly; the 12V 0.08A rating means it draws minimal current.
