But we know nothing about where OP lives and how the climate is there. If he lives in Australia for instance, then thoes temps would suggest he keeps his pc in fridge.
Nice guess on location, so you think those temps (especially during gaming) are fine?
They are fine for now yes. When you start to get into the higher 80s and up, thats when you should worry. But for now you're ok. As far as overtime though, it can cause long term damage to the CPU. Having the CPU run that hot for months at a time can cause damage to it. The first thing to try though, is to re apply thermal paste, too much can be very bad, and too little can be just as bad as well. Also do you have a aftermarket heatsink or are you using the stock cooler? If you're using the stock cooler, than that might be your problem to the high temps, are those arent very good.
