I just basically finished my S4 Mini build, and I'm running a i5 7600K, but it gets pretty hot under heavy load (Witcher 3 on Ultra settings) and it seems to be hitting around 75-80 degrees occasionally (auto boosting till around 4.4GHz), but it normally hovers around 63-68 degrees. I have a Noctua L9i on it, which I know isn't designed to handle that much heat but is this safe...? Is there a better fan I could replace my current one with to cool it down? Would a 120mm fan on top of the Noctua fan work/help?
