Fancontrol of a CPU/GPU custom loop?

I currently have a custom loop cooling the CPU with a remote controlled pump/res combo from Enermax. The loop has no way to measure liquid temps, so I'm stuck with using the BIOS Smart Fan on my Gigabyte to control fans...

... however I've got a GPU block coming in real soon, which means the sensor on the CPU isn't going to be particularly accurate anymore (especially in GPU only scenarios)

How would I go about getting the best fan control based on sensor readings in Windows? I've tried downloading Speedfan, but it doesn't appear to be detecting my Ryzen 4 sensors at all, HWInfo can read them all, but I see no way to control the fans there.
 
The best way to do it would be to add a water temp sensor and invest in a Aquaero and control fan speed by the water temp. That is not a cheap solution though. The way I do it is I have a pair of water temp sensors (inlet/outlet) and have the fan on a fan controller (Phobya Touch 6) and if the water temp creeps towards a certain temp I don't want it to reach just turn the fans up. Most of the time though I just leave the fans at 1000rpm and it keeps the water temp between 17-22 degrees C (my rads are mounted on a windowsill sucking outside air through them).
 
I use a grid+ v2 for my fan control and have it change fan speeds based on gpu temp. Reason being that the GPU puts far more heat into the loop and the temperature rises steadily with water temp.

Aquaero 5 LT or 6 LT have same control as 5.25 bay mounted models without screen and mount inside of case. It's easier to use them with monitor, keyboard and mouse anyway.
 
I've got a phanteks pwm hub and am using that to power 3 pin fans on the rads based on CPU temp. Its not ideal but it works pretty well. Only downside is the hub doesnt drop below 8.5v (ish) so it doesnt go as quiet on idle as I'd like.

I've looked at the aquaero but need to do more homework to understand expanding it as I have 5 fans that need control rather than the 4 the LT has.

If you could add a couple more fans I suspect they will idle at lower speed. The Phanteks PWM controlled hub minimum/maximum voltage changes dependent on load.

I'm looking for a gadget to control my fan curves based on water temperature with input from a XSPC temperature sensor (already installed).

What's the difference between the Aquaero 5 LT & 6 LT? The 5 is half the price of the 6.
 
Aquaero 6 LT handles more fans and has more PWM channels than Aquaero 5 LT does.
5 uses analog voltage control, 6 uses switching controllers
5 has 2x PWM channels, 6 has 4x with power + 2x just control signal.

I have a 5lt and it's great. The only problem is you only get ONE pwm fan connection. I've split all 4 radiator fans off from the one pwm connection, and I use one of the voltage controlled channels for my case fans.

I measure loop water temps and ambient temps

The fans spin based of the delta between the water temps and the ambient temp

While it only has 1 4-pin PWM header it has 2x 2-pin PWM control headers that only supply PWM control. To use them you would need a custom lead with 2-pin plug for PWM and a Molex or Sata for 12v power. The Sata or Molex plug is no problem to get, but the 2-pin one I don't know where to find.
