Galaxy Note 3 Feeling warm

[woifx5]

Hey guys just got a galaxy note 3 and when I play some games on it, 1. It heats up,
And 2. When I insert my own SD card, the area at the SD card heats up

Also I checked with a program for my temperatures:
CPU: 35-40 Degrees
Battery: 27-30 Degree's
Are those temperatures ok for my phone? Or Is it going to cause me troubles?

So, I shouldnt be worries about those temps while playing and such correct?

Now its 50 Degrees while playing GTA SA on it, Is that ok?
