1) Yes, you can use smartboost to set a minimum start % or voltage and for how long. Using this you can find what the lowest start up value is, set that and then allow the fans to throttle back from that to the lowest setting they will run. Then you can have them automatically spin up to your 75% when the water temp sensor (I assume you have one of those) gets above a certain point. Or you can use something like average CPU/GPU temp but it really is the water temp you care about. This keeps the fans and pumps from spinning up and down just because you hit 100% load for 2 minutes.
So for my AP-15's I have it set to 35% and then minimum fan power to 25%. They won't start at only 25%. You can also use "hold minimum" to prevent them from turning off if you want. At the very bottom you set the minimum and maximum RPM or power so you could set that to 2200 RPM and the max so they will never run above that regardless of the load.
You get one 3 pin fan / pump header, one USB header, two aquabus 3 pin headers (do not confuse these with fan headers), and one temp prob 2 pin header. The Aquabus 3 pin headers are how you daisy chain these modules to each other and then back to the Aquaero 5. So you would use a 3-pin distribution block or combine your wires together to a single header to plug in to the power-adjust and keep it below 25 Watts (2.08A) continuous per.
I just realized you did your math with 8 fans per PA-Ultra not 4. There is only one fan header capable of 25W continuous / 48W peak per PA-Ultra not two, so you need to double your order and fill two bays with PA-Ultra threesomes. Again, if you are just going to run them at 75% all the time, this is a very expensive solution.
The value of the Aquasuite / Aquaero combo is how it can keep your rig dead silent when your just surfing the web and auto ramp it up based on any parameters you set. It also provides amazing levels of monitoring.
You can see at idle my dual 35x pumps are running at 1100 RPM for 0.2 GPM flow and my fans are running at 30% ~ 600 / 700 RPM. This is because I am at a 2.5C air/water delta and only 1.9C temp difference from water coming off the block into the rads vs. water coming out of the rads.
And here is my simple ramps:
I have my pumps and rad fans ramp up based on water temp coming into the rads and my case fans ramp based on the ambient temp inside the case.
Make sure you are getting PA-Ultra, not standard PA's because they do not handle as much power.
Let me know if you have any other questions.
