I think 83c on a GTX-1080 (at full utilization) is OK. It can go to 99c, IIRC.

Set Thermal Controller to Manual (uphill) Curves. Adjust Curve for Front Fan to be a bit more extreme. 

Hey, 

Thank you for the response I am a complete newbie with the alienware command center. Do u have an example on where to set the fan curve ill attach the current setting on the command center.  Thank you 

On the one screen, select Manual. Other the other select Use Curve.

You can try different linked Sensors (I've been using "CPU-Sensor" lately).

Do I have to select the % or should just leave it the way it is? 

Whatever works best for you.

For example, the minimum could be 10% and the Max could be 90%.
