The Arctic P12 PWM PST A-RGB is a semi-passive case fan in 120 mm format. It offers PWM speed control and only switches on when needed. Thanks to its digitally addressable RGB lighting, the Arctic P12 PWM PST A-RGB 0db also looks good. The set offered here consists of a total of three identical fans. These can be installed together in one case and both their speed and RGB lighting can be synchronised.
