[URL] is a very good manual controller. kingwin makes one that is mounted in a 3.5 bay [URL]  
I added a new Arctic P12-TC fan to my new R10.  I was hoping to control this fan separately from the other fans so I plugged it into the CPU Fan slot on the Mother Board.  (CPU is Liquid cooled, so this slot was empty).  Questions: Is there a way to add this fan to the Alienware Command Center? If not, how can I regulate the speed of the new fan using the CPU Fan slot? The BIOS doesn't seem to have any hardware control that I could find for fans.  If the answer is a 3rd party app like HWiNFO, how does that work with Alienware command Center?   Thanks in advance for reference I have a 5600x and a 3080
