Vszerda AFB0812SH 80mm case fan 12V 0.51A 1000-4500RPM 4-pin PWM

80 mm PWM case fan for compact builds

The Vszerda AFB0812SH fits 80 mm mounting points and draws 0.51 A at 12 V. Its four-pin PWM connector allows the motherboard to regulate speed between 1000 and 4500 RPM. Maintenance-free ball bearings are designed for long service life. The fan suits small-form-factor cases or supplemental cooling spots where larger units cannot fit.

Sustained airflow and pressure at speed

At the top of its range the fan moves up to 63 CFM and develops 64 Pa of static pressure, maintaining flow through restrictive grilles or dense heatsink fins. Noise rises to 44 dB under full load, dropping to 15 dB when the curve idles near 1000 RPM. The PWM loop keeps output matched to thermal demand without manual intervention.

Four-pin PWM control decides compatibility

The 4-pin header supplies a tachometer signal and accepts PWM duty-cycle commands from the board, while remaining electrically compatible with three-pin and two-pin headers. If your motherboard lacks a PWM header or you need voltage-only control, speed regulation will be limited to the board's DC mode.
