Case: Fractal design R4 http://www.fractal-design.com/home/product/cases/define...
Motherboard: Asus M5A97 R2.0
CPU: fx-8320
CPU Fan: Hyper 212 evo

When i am gaming, the temperatures of my cpu, mobo and gpu increase but stay at expected temperatures.
CPU: 45-55 degrees
GPU: 60-65 degrees
Mobo: 30-35 degrees.
These are normal temperatures right? (HWmonitor)

So basically i have noticed that when i touch my right side panel of the tower case, at the top right corner where the CPU is inside, the panel is quite warm - it is NOT hot like you can't touch it for long, you could keep your hand on the panel forever.

However, the side panel is cold everywhere else, it's just the top right corner of the right side panel.

I'm just assuming that it's because the cpu has a high temperature some of the heat reaches the side panel, BUT should it be doing this? Is this normal?

But when i'm not gaming or doing anything intensive, like browsing the web or watching a movie, the side panel is cold everywhere or just very faintly warm in that area, (top right corner where the cpu would be inside). Also I just built this pc with a friend a few weeks ago, if that means anything.

Please give any response, quite worried here :( - Thanks, you guys are awesome!
