I'm fairly new to computers, the other day I was playing battlefield 3 and I noticed extremely high temperatures coming from my cpu, (amd a10-5700) and instinctively I shut down my system to let it cool, after a while I booted it back up and noticed idle temps of 70-80°c so I shut it back down and it's been off for a while now and I just needed some insight as to why the extreme temperatures, I recently upgraded my Gpu as well to a Radeon r7 265 2gb, also I have not done or attempted any overlooking. Any feedback is greatly appreciated, thanks in advance!
