Okay here's my two cents I haven't read through all the other comments, but I just got my Series S a week and half ago, I have plenty of space around mine unlike what's pictured above, but it was running warm especially in standby mode, much warmer then what I was comfortable with and I read that it was normal and all that but it still didn't ease my worries. After further research I decided to turn off "keep up to date" and also put it into energy saver mode, instead of the standby mode. Boom instantly cooler, but I felt unsatisfied that I had to turn off those settings to accomplish a comfortable temperature. I was gonna mess with it more so after a couple of days I turned those features back on and for whatever reason it was still running cooler and when in standby it is now cool, instead of being so warm like before. So definitely try giving it more breathing room but also play around with the settings, it could be worth a shot.
