A 120 mm sleeve-bearing case fan running at 12 V and 0.4 A with a two-pin connector
The MWP1225L12S is a 120 mm fan with a sleeve bearing and a two-pin power connector. It runs on 12 V at 0.4 A and has no LED lighting. The black frame measures 120 by 120 by 25 mm. It suits builders who need a basic airflow device for a standard mounting pattern.
Under sustained load the sleeve bearing delivers steady rotation at the rated voltage and current. The two-pin design means speed stays constant without PWM control. Acoustic output remains consistent during long sessions because there is no speed ramping. The fan is intended for case ventilation rather than high-static-pressure heatsink duty.
Verify that your chassis has 120 mm mounting points spaced for a 25 mm thick frame. Confirm the motherboard or fan controller provides a two-pin header; a four-pin PWM header will run the fan at full speed only. No adapter or additional wiring is included in the package.

The 120mm sleeve-bearing fan draws 0.4A at 12V, so sustained operation stays at modest power levels; sleeve bearings typically run quieter at low speeds but can grow louder as lubricant ages.
It connects directly to any standard 2-pin 12V fan header; if the board only offers 3-pin or 4-pin headers, the 2-pin plug fits the outer two pins and will run at full voltage.
At 25mm thick the fan matches the classic 12025 form factor, so it fits the same mounting holes and clearance envelope as most older 120mm case or heatsink fans.
