The ARCTIC F12 PWM PST 120mm Case Fan is a PWM-controlled case fan designed for builders who want coordinated, efficient cooling across multiple fans. Its Fluid Dynamic Bearing and optimised blade design balance airflow with a low noise level, while PST (PWM Sharing Technology) lets all fans respond to a single control signal.\n\n Why This Product\n\n--\n\nPWM Sharing Technology synchronises fans\n \u2014 PST allows multiple fans to listen to one PWM signal\u2014typically from your CPU cooler\u2014so they spin down at low load and accelerate together when cooling is needed.\n \n--\n\nFluid Dynamic Bearing for durability\n \u2014 The sealed oil capsule prevents lubricant leakage, delivering the quiet operation of a sleeve bearing with a much longer lifespan.\n \n--\n\nPWM control for precise regulation\n \u2014 The motherboard adjusts fan speed in real time to match cooling demand, maintaining the required temperature while keeping noise minimal.\n \n--\n\nLow noise at full speed\n)
