Nexus 5672UP Fan Speed at 100% after upgrade
I recently upgraded 2 5672UPs from 7.0(2)N1(1) to 7.0(5)N1(1) and the fan speed stays 100% usage all the time. In version 7.0(2)N1(1), the fans would reduce speed in about 7.5 minutes after a reload. Does anybody have any ideas why the fans will not reduce speed in version 7.0(5)N1(1)? Thanks,   Scott
