The speed ofP12 PWM PST can be adjusted using PWM signal from the motherboard. Please follow this procedure to adjust the settings on your motherboard.
You can control several fans from one unique header using the integrated PST extension however, we
recommend to limit the number of fans per header to 5 as the current may be limited to 1.0 A per
header (please refer to your motherboard manual). The speed monitoring will be done on the first fan in
the daisy-chain.
To control more than 5 fans from one unique header, we recommend you to use the ARCTIC Case Fan
Hub. Its external SATA power will circumvent the header current limitation.
Adjust the fan speed by control input voltage accordingly.
