I asked why Aquasuite cannot send flow rate date from the High Flow Next to the D5 Next about a year ago on the Aquacomputer support subreddit under R/Watercooling. My D5 Next virtual flow sensor, even after calibration, was very inaccurate and did not work at all if flow rate was below 180 L/hr. If I enabled the D5 Next alarm, it would go off even when my flow rate was fine. Shoggy (Aquacomputer rep) told me that the D5 Next has very limited memory for firmware and they had to get very creative to fit new firmware updates into it. I ended up getting cable #53294 and connecting my High Flow Next Signal output to the D5 Next Fan/Flow header to get the High Flow Next flow rate data into the D5 Next. The setup is a bit convoluted but it works.

I don't know about your second question. I leave my D5 Next at 65% which results in a flow rate of about 220 L/hr. I don't think there is much to be gained by varying the pump speed. I can't (and don't need to) connect a fan to my D5 Next because I am using that header for the connection to my High Flow Next.

Do you not use AquaSuite? If you do, I'm pretty sure all devices should be aware of eachother and therefore work in conjunction with one-another via AquaSuite sort of acting as the "brain" between all devices and therefor you can just plug the High Flow Next separately into the motherboard's USB instead of into the D5 Next pump.

Yes I do use Aquasuite, and all of my Aquacomputer devices that have USB ports are connected to the mobo either directly or through a Hubby 7 internal USB2.0 hub.. I can assign the High Flow Next Flow Rate to a soft sensor in the D5 Next tab, but that does not make the D5 Next use that data as the source for its alarm. The only way to do that that I am aware of is to connect the High Flow Next Signal header to the D5 Next Fan/Flow header with cable #53294. If you know of a way to do that in Aquasuite, please share.

You have to follow the procedure described in the manuals. You tell the High Flow Next in the Alarms section to generate high flow sensor #53068 signal (DP Ultra, Inner diameter >7mm) then in the D5 Next Sensors section, for Sensor 2, select Sensor type Aquacomputer high flow #53068, DP Ultra Coolant, and Fitting Type >7mm. High Flow sensor #53068 is not even sold anymore but that is not relevant to this setup. The High Flow Next has to generate this signal and the D5 next has to be set up to receive this signal. When I first set this up, the flow rate were a little different. Sven from Aquacomputer told me this was because they needed to update the D5 Next firmware to have calibration values that matched what the High Flow Next outputs when set this way. They don't update the D5 Next firmware unless they absolutely have to and they were not going to do it just to fix this issue that is not commonly used anyway. The next time they updated the D5 Next firmware they included the necessary changes and now the flow rates match exactly.

This a perfect example of how all this is so confusing.

If AquaSuite is being used and the High Flow Next's flow rate has been assigned to a soft-sensor in the D5 Next's tab, then why is the D5 Next still not using / not able to use that data-source for it's alarm? Why is it necessary to have a physical/hardware connection between the High Flow Next and D5 Next if all the necessary data/sensors are already present in AquaSuite?

This is precisely why I keep asking a million questions regarding what cables I should buy, what features do I gain/lose, etc. via USB connection & AquaSuite VS direct component-to-component connection.

If a sensor is transmitted to a device via software, it is very likely that there will be false alarms at some point or regulations will not work by chance.
1. the source of the sensor is not available
2. some software is not running
3. ...

all this only works properly if the sensors are connected directly to the device that is supposed to use the sensor.

Fans and RGB are usually not critical, but different conditions apply to a pump controller.

So does that mean the D5 Next should be plugged directly into a Quadro/Octo rather than via USB to the PC?

No, these devices can not be connected to each other anyway. The pump must be connected via USB.
