From the fan hub, I send the usb plug into the D5 next header.

I am not sure but it sounds like you have connected the USB interface of the hub to the USB interface of the pump. That will not work of course. These ports are meant to be connected to a USB port of the mainboard.

On the other side you would not be able to use the software of both devices if you would have done that. So, your current setup is not quite clear.

I don't know that hub in detail but it must have some sort of fan input port where you would connect the fan port of the pump. This way the hub can pick up the signal and process it. That mainboard sync option sounds correct.

I am pretty sure your problem is the fan hub. Have you alredy tried to connect a fan directly to the pump?

Have you read the D5 Next Manual? Sections 11.2 and 11.3 explain how to use the Target Temp and Curve Controller modes.

The D5 Next does have a 4-pin PWM fan header that can also be configured to connect a flow sensor. I don’t think it's possible to plug a standard 9-pin USB2.0 connector into this PWM fan port, and if you somehow did, it would not work. I looked on Lion Li’s site. There is a UNI HUB controller and a UNI HUB – SL L-Connect 3 Controller. If you specified which one you have, I could look at what cables are provided with it.

This is a 9-pin USB2.0 connector: If it is wired for only 1 USB port, there are 4 wires used: 5VDC, Ground, Data (+), Data (-)


This is a 4-pin PWM Fan connector:


This is the back of the D5 Next Pump:


Click on the images to enlarge. I do not see how you could possibly plug a 9-pin USB2.0 connector into the 4-pin PWM fan header on the D5 Next. Since Aquasuite is controlling your Lion Li fans, I think you have plugged in a 4-pin PWM connector from the Lion Li controller in the D5 Next fan header, and it's working because you can control the fan speed in Power Preset Mode. To use Target Temperature or Curve Controller modes, you have to assign a temperature in Aquasuite to be used as the control source for the Target Temp or Curve Controller. The D5 Next has an internal coolant temp sensor, so it would be easy to use this as the control source. Here is a snip of the D5 Next Fan Mode section with the D5 Nest coolant temp sensor selected as the temperature control source for the Fan port in Target Temp mode.



Many people prefer to set up a Virtual Sensor in the Aquasuite Playground that is Coolant Temp minus Ambient Temp (referred to as Delta-T). Doing this, of course, requires a coolant temp sensor and an ambient temp sensor. Using CPU temp is not advisable because CPU temp jumps all over the place. I suppose you could bring the CPU temp into the Playground and use the functions there to make a Virtual Sensor that is the average CPU temp, but just using the coolant temp or Delta-T would be better choices. You have not mentioned what temps you are monitoring in Aquasuite or if you have assigned a temperature sensor as the control source for the PWM fan port on the D5 Next pump. If you have not done this, the Target Temp and Curve Controllers cannot work because they are both based on a temperature, so you must assign one.

I have the L connect 3 controller. From the controller there is a cable that splits. One end is the rgb cable, the other end is the 4 pin pwm. I initially had the pwm plugged into the D5 next fan header. I now have it plugged into one of the motherboard chassis fan headers. Now that its plugged into the motherboard, aquasuite doesn't seem to be able to control it at all now. Thanks for all the help so far though!

If the Lion Li PWM Fan cable is plugged into a mobo fan header, Aquasuite will NOT be able to control the fans. Aquasuite does not communicate with the mobo fan headers. For Aquasuite to control the fans, that PWM fan cable MUST be plugged into the D5 Next fan header. You had the Power Preset mode working before so you were close, but moving the Lion Li PWM Fan cable to a mobo fan header is a step backwards. If you want Aquasuite to control the fans, you have to move the Lion Li PWM fan cable back to the D5 Next Fan header. Do this, then make sure Power Preset mode is working. Then switch to Target Temp or Curve Controller mode. At this point you must assign a temperature sensor as the control source in Aquasuite. The easiest temp to use is the D5 Next built-in coolant temp sensor. I am not sure, but Aquasuite may select this temp sensor by default. If it doesn't, you have to select it as shown in my last screenshot where it says "Controller Source". Click on the plus sign and select a temperature control source.

I suggest you download and read the D5 Next owner's manual which is available in the Support section. Sections 11.2 and 11.3 explain how to use the Target Temp and Curve Controller modes. If you click on THIS LINK the D5 Next English manual PDF file will download.
