A 120 mm case fan with a 2-pin connector, 12 V .3 A rating and sleeve bearing for quiet airflow
This 120 mm fan uses a sleeve bearing and runs on 12 V at 0.3 A through a 2-pin connector. It is built as a simple airflow device for case ventilation or heatsink mounting. The black frame measures 120 by 25 mm and includes no LED lighting.
The 2-pin connector supplies constant voltage without a PWM or tachometer signal. Fan speed cannot be regulated by the motherboard and the system cannot monitor rotation. Voltage reduction through a fan controller or resistor cable is the only way to lower noise.
Sleeve bearings run quieter than ball bearings at similar speeds but wear faster when mounted horizontally or in high-temperature zones. Builders who need long-term horizontal operation or continuous high-RPM duty should choose a different bearing type.

The D12SH-12 runs at 12V with a 0.3A draw, giving higher airflow than the medium or low-speed models listed.
At 12V and 0.3A the fan delivers its rated maximum airflow, suited for general case ventilation rather than focused CPU heatsink cooling.
The 2-pin design supplies constant 12V power without RPM reporting or PWM control, so speed cannot be adjusted by the motherboard.
