my pc overheats for no reason, why?

[Game_2]

I just builded my new gaming pc which is:

CPU:AMD fx 6300 black edition unlocked
GPU:AMD radeon hd 7950
PSU: 650w EVEA Gold Tier
RAM: 8GB
HD: 1TB
MOBO: MSI 970 gaming

And when i play games it really heats up. I can feel my pc is very warm and it bothers me... I mean nothing happens to the game, doesnt lag or anything im just wondering if i should worry about it. I have a Vibox case and it shows me the temperature of my pc it goes up to 45'C after like 2 hours of gameplay..

I would be more concerned if your PC didn't generate any heat.

You have an extremely hot CPU, motherboard, and graphics card, in fact, some of the hottest-running components designed/manufactured in the last decade. If there is no performance impairment, you're probably fine.

45C case temp is on the hot side of normal for a poorly designed case and/or bad airflow. I once ran an fx8320 with an HD7950, and case temps reached damn near 60C after 5 hours of on and off gaming and stress testing.
