MacBook Pro (Late 2013) [Fully Upgraded] - too hot?

[MacBook Pro (Retina, 15-inch, Late 2013), 2,3GHz Intel Core i&, 16GB 1600 MHz DDR3, NVIDIA GeForce GT 750M 2048 MB]

Dear Apple-Community,

My MacBook is one year old now, and recently my Fans have been getting loud and the Aluminium stripe bellow the display is getting very, very hot. This happens although I only have Safari, Mail and Apple Music open. I already did the Diagnostic & Hardware test and it should me that all hardware components are intact. Still I would think that my bigger processor would handle pretty big stuff before needing to speed up the fans.

Is this normal for this model or is there some sort of malfunction? I remember my old macs not having this problem in their first years.

Thanks!
