Addressable RGB for full colour control The P12 PWM PST A-RGB has 12 digital A-RGB LEDs in the centre fan wheel. These can be controlled independently of each other and are compatible with the common A-RGB standards of leading motherboard manufacturers. This means the fab can be fully illuminated directly via the A-RGB mainboard connection or via an external controller and synchronised with the lighting of other hardware. ARCTIC's Partner SignalRGB provides a comprehensive solution for synchronising and customising lighting. 0 dB mode - zero rpm The speed of the fan can be reduced to a standstill using PWM. This allows silent operation at idle while guaranteeing maximum performance when required.
