The fans need 38.16 and 12.96 watt in theory. So in total it is a bit more than 50 watt. The is pretty much. The aquaero can take a load of 60 watt in total but the problem is that when you slow down the fans the dissipation loss will increase. So if it could be done than you have to use the waterblock for the voltage regulators.

You can use a pump directly with the aquaero but not with the mentioned setup since this is way too much load. To monitor them you would have to connect their ROM signal to the fan channels. So you will lose these channels to monitor other stuff.

To extend the aquaero with further channels you can use the poweradjust 2 controller. Up to six controllers can be connected so you have a total of 10 fan channels.

The aquaero can provide a total power of 60 watt but in this case the voltage regulators will get very hot so you have to watercool them:

Each fan channel on the aquaero 5 is able to handle 19.8 watt but the overall power of all channels combined should not exceed 60 watt.

With each poweradjust 2 you will add a new fan channel which can take a load of up to 25 watt.

There is no problem to use some fans on the same fan channel by using y-adapters but you have to make sure that they are within the given maximum load. If they draw too much power you will not damage anything but it will not work because the aquaero or the poweradjust will disable the overloaded fan channel.

That would work without any problems but is not really necessary since you could also use y-adapters as long as you are within a valid power range.

The poweradjust is being connected to the aquabus (3-pin cable). You can just go from controller to controller. They can not be connected to USB at the same time.

120 mm: 12 V x 0.53 A = 6.36 W
140 mm: 12 V x 0.36 A = 4.32 W

So on the aquaero you would have 45 W load which should be fine since it also lefts some space for the fact that the voltage regulators will run hotter when you turn down the speed of the fans. Anyway I still recommend to use the waterblock for this setup.

The setup with the poweradjusts is OK since the pumps will draw more power than the fans.
