Here is my build idle with chrome open with a couple of tabs, and with DotA 2 or Arma III the CPU temps go up to 70~
Recently in all my games I get some lag spikes that I thought might be related to tempretures of my machine, but I played a game with speccy on my other monitor and the temps stayed pretty stable around 69c-74.
I'll run 60 fps no problem and the in the middle of a fight with a bunch of particle effects and other visual effects, it'll freeze up until the fight is over. Is 70+ too much for my CPU?
