I have two older Dell Precision R5500 workstations.  One runs Windows 10, the other Windows Server 2016.  Both show the 6 fans, but only the Windows 10 one shows the PWN control or anything in the Speeds tab.  Under advanced again one shows the PWN values one doesn\’t.  Any idea why being basically identical systems other than the OS?
