Having heating issues

[Craftedclouds]

I've had the cybertron Borg q (cheaper version on amazon) for about a year how and its been running fine until recently. My PC has randomly shut off twice now and im very worried about my CPU (AMD FX-4130) I have replaced thermal paste and it seems to have helped a little bit but I don't know what could have caused this issue to arise so quickly and out of nowhere. Any advice is greatly appreciated.

How's your case ventilation ?

Apevia X-Sniper 2 Gaming Mid-Tower is the tower I still have

That's nice but does it have some fans and good air flow ? It's not enough to cool CPU but whole thing has to be well ventilated to take that heat out.

It has 2 case fans and of course my heat sink and sits on top of my desk I wouldn't know why the cpu would get so hot.

What are the temps when it shuts down? Are you sure it is even shutting down due to heat? Your PSU could be giving out and causing the shutdown. What CPU HSF do you have, and are the fans working and dust free?
