Super silent 12cm fan with S-FLOW blades supplying 30 more airflow than a standard fan at the same speed The greater performance combined with PWM automatic speed control allows the fan noise to be kept to a minimum The Apache fan creates more focused airflow providing blind-spot cooling which makes it an ideal solution for a case or heatsink fan HDB (Hydro Dynamic) bearings extend fan life & further enhance noise reduction IP54 military standard ensures the fan is dust & moisture resistant It’s powerful quiet & tough!PWM is a widely available feature on all current Intel & AMD platform based motherboards It is more accurate than voltage regulation energy saving & a fully automatic way of controlling the fan speed PWM provides ultra quiet acoustics during normal PC use & high performance cooling under high system load The Optional Akasa AK-CB002 cable adapter can provide the system with two additional PWM connectors if needed
