NA-FC1, Controller ventola PWM 4 pin (nero)

All Noctua 12V PWM and 5V PWM fans, many third party PWM fans. This makes it ideal for manually slowing down high-speed PWM fans such as Noctua’s iPPC series to achieve consistently quiet operation. “No stop” mode: prevents the fan from falling below a speed of 300rpm in order to avoid BIOS fan errors.
