PX013ANC loud humming

PX013ANC installed for just over a week..This unit is very loud.  So much so that my wife won't even sleep in the bedroom..The unit is also quite warm.

I've read some other posts with same problem, but I couldn't figure how to get in on those discussions.  If these units have this problem frequently, I need something different.  I was fine with my old (non-x1?) DVR until it died.
