Zyvpee FFB1212EHE -5N31 120mm 12038 3 Pin Case Fan

High-Airflow 120 mm Server Fan

The Zyvpee FFB1212EHE is a 120 mm by 38 mm case fan built for servers, mining rigs and inverter enclosures. It uses a ball bearing and a three-pin power connector running at twelve volts. The black, non-LED frame targets builders who need maximum airflow over silence.

Three-Pin Voltage Control Limits

A three-pin connector adjusts speed by varying voltage, so the fan cannot use PWM signals for finer granularity. At full power it draws three amps and spins at four thousand RPM, producing one hundred ninety CFM at fifty-nine dB(A). Speed regulation depends entirely on the motherboard or controller voltage range.

Replaces Standard Thin Fans

This thirty-eight millimetre thick unit replaces thinner twenty-five millimetre fans when static pressure and raw airflow matter more than noise. The jump is worth it for densely packed server chassis or GPU mining frames where component clearance allows the extra depth. It is not for quiet desktop builds or slim cases that only accept standard thickness.
