In the system log, the above message was only message listed. I rebooted the machine again and entered the BIOS. All fans were working normally, including the CPU fan. I booted into Windows and then opened the case. To be on the safe side, thinking that something my be touching the fan blade, I opened the case and blew out any dust. This unit is new and just installed last month. Upon arrival, the workstation booted up normally with no issue and I could detect no humming at all.
I was working on a Dell 7010 yesterday after getting a report that the workstation was producing a 'humming' noise.
