Is it normal for the Arduino Yun Rev 2 to heat up?

i connected it to my laptop and in like 30-1 minute the chips from the back of the Arduino heat up

is this normal?
because i am very concerned, this Arduino Yun is brand new and i would be disappointed if it burns or doesn't work

Hey, I'm a newbie here too so won't help much, but at least I can tell you mine is pretty hot too. Not sure if that's an issue.
