You ask: "What can I try to make it sound less"

Some sound is normal. Not knowing how loud the noise is, or if it is the same volume and pitch across the full speed range, you may have air in the loop.
You can adjust the pump speed to the lowest noise level and use that as the sweet spot for your loop.


You say: "I can not also use the software to control the pump such as the speed"
"i hava now usb on d5 and aquabus same on my motherboard i can now low to high with my d5 i have settings to the aquabus and restart system with aquabus no usb on the d5 and i can noting now"

It sounds like you can control the pump with the USB connected, but not with only the aquabus.
If the communication priority is set to USB (default), and the USB is removed, you have no control over the pump using aquabus.
Most likely you need to reconnect the pumps with USB and set the communication priority in the pump tabs to aquabus.
Then you can remove the USB again.

I am not sure if I answered your question, because I may have misread the questions... if not, re-ask again
