120 mm case fan spins at 1500 RPM on 12 V power for SilentiumT5 cooling
The OEM Industries AF12025 is a 120mm case fan designed for 12V operation at 0.15A. It spins at 1500RPM and uses a two-wire power connector without LED lighting. This black fan suits builders replacing a worn unit in a compact chassis or upgrading a stock cooler for quieter airflow.
Swap this in when an original two-wire fan becomes noisy, fails, or cannot move enough air through a tight heatsink. The jump is worth it if the existing mount accepts 120mm spacing and the header supplies 12V without PWM control. It does not serve builds that require four-pin speed regulation or addressable lighting.
Installation needs a standard 120mm screw pattern and a 12V two-pin header on the board or fan controller. The low 0.15A draw leaves headroom on shared fan headers for additional cooling devices. It frees up a four-pin header for PWM components while delivering steady airflow to the CPU heatsink or case exhaust.

Yes, the 120mm frame matches the standard four-hole pattern used on 120mm case vents and radiators.
Plug the 2-wire connector onto the 12V DC header observing polarity; the common error is reversing the wires, which prevents the fan from spinning.
Replace the fan when bearing noise appears or airflow drops noticeably; at 1500RPM typical sleeve-bearing life is several years of continuous use.
