4.3. Connector “Fan 1/2/3/4”
Voltage regulated fan outputs with speed signal processing. Maximum power
output 19.8 W (1.65 A at 12 V) for each channel. Maximum power is
dynamically limited through temperature monitoring.
Special feature “Fan 1”: This connector can alternatively be connected to a
flow sensor. If connected to a flow sensor, select “Sensors” → “Flow sensors”
→ “Flow 2” from the menu and set “Mode” to “Fan 1 = Flow sensor”.
Special feature “Fan 4”: This connector can be used for conventional fans or
PWM controlled fans. For PWM fans, select “Outputs” → “Fans” → “Fan 4”
from the menu and set “Control mode” to “PWM-regulated”.
Pin assignment: Pin 1: GND
Pin 2: 0-12 V
Pin 3: Speed signal
Pin 4: PWM signal (Fan 4 only)

You don't need pulse-width modulation (PWM) to control the fan speed. What you need is to control the potential (voltage). And that is just what the PowerAdjust 2 does, without any transition from 0 to 12 volts. You can regulate normal 3 pin fans and pwm fans with 4 pins as well. But a pwm fan will be treated like a 3 pin fan by adjusting the voltage and not via pulse-width modulation. If you would ask me, I prefere the control via voltage, it's much 'cleaner'. Because some fans generate a buzzing noise after dropping into resonance with some frequences from the pulse-width modulation. That can't happen when you regulate your fans by voltage.
The single channel Power Adjust 2 can handle a max. power of 25 Watts total.
The Aquaero 5 does also adjust the fan speed by adjusting the voltage. You have 4 channels for that with a max. power output of 19.8 W (1.65 A at 12 V) for each channel. With splitters you could regulate the fans in groups 4x4 as long as the max. power consumption is less then 19.8 Watts total of each channel.
This information is very helpful . Thank you. I'm using Silenx fans listed at 2.04w so grouping 3 or 4 together should not be a problem. And as far as I can tell they are not PWM fans.Zitat
