I am wondering what the safest overclock with the stock intel cooler on the G3258 would be with it still lasting at least a couple years. The motherboard I am using is a gigabyte z97-d3h and I have a 600 watt PSU so power shouldn't be a problem, especially since my gpu is only a 750 Ti. I do not need an insane overclock, that's not what I am asking for here either.
