Cpu or Psu Possible Overheat Problem

[George_Revolted]

I recently upgraded my PC with a new graphics card, ssd, case and motherboard.
I installed the psu on the bottom with the fan facing down, because the case has a relevant opening. The two front fans are intake and the back is exhaust so is blowing out of the case.

Everything was fine until I run my first game (Star Wars Battlefront). I was playing without a problem when my PC shut down unexpectedly. I had this problem with every game.

I checked the CPU temp and it was really high (50-60 Celcius Idle and 78 and rising when gaming) so I disabled the Q-fan Control from the BIOS. My CPU fan is running full-speed.
I also installed new thermal paste.

As you can image I'm still facing random shut downs and the PC will not start afterwards, unless I let it cool-down.

Is there a compatibility issue with the motherboard and CPU?
Is my PSU not powerful enough?
Should I install my PSU facing up?

Please help!

Well, the PC shutting down is a good thing. The idle and under load temps are quite big and that is why is shutting down.You can thank your motherboard for that.Your problem is your CPU fan. It's not much better than AMD's stock CPU cooler.

I have just run a cpu stress test and when the cpu reached 93 celcius it shut down. Thank you for your answer.
Could you suggest another CPU cooler?

well....It depends on your tower. If you can fit the 212 Evo, go for that. it will keep your CPU at 45C-50C under full load.

It doesn't support AM3+ CPUs so I'm gonna search for something like that.

Thank you again my friend.
