mine gets hot as well its on 24/7 and flat like yours.
its a natural thing the fans dont kick in until you turn it on to play it so do that once a day for a few minutes to cool it down .
if your worried about it use the search bar on this site and type heating and things like that there have been tonnes of threads about its heat
