Tivo Bolt overheating?

It seems as if my new TiVo Bolt is overheating. We replaced the stock hard drive with the Toshiba and it was working pretty well. It's frozen up a couple of times but sprung back pretty easily. It always happens when playing a video via the Amazon app.

It's in a cabinet, on top of a dvd player, the way our old TiVos were. Is this the fan issue that's being spoken about in the other threads? Do we need to do a fan replacement? Could someone dumb this down for me please?
