It's just a read issue it looks like. When assigned to a controller, such as a curve based off of the CPU temperature, the fans will ramp up as they are supposed to. However, the RPM reading is not shown in Aquasuite. The connection between the Lian Li controllers and the aquaero is just thew tacho line for speed control.
Edit:
The reason the RPM is not read is because the 4 pin connector from the Lian Li controller only has the tacho line, and not the sense line. I can live with not seeing RPM, it will still control just fine.
Thank you both for your help.
