Recently put together my i5-2500K build. At first I didn't think of overclocking really because I was just using the stock cooler, but I checked and compared my temps and they were very low compared to others using the stock cooler probably because my case has great airflow. So I decided to overclock it a little bit to 4.0 GHz and the temperatures barely increased, only by a few degrees. I thought overclocking on the stock cooler was a bad idea but it still runs pretty cool. It stays at or below 35C at 4 GHz for all 4 cores - that seems strange to me. Also, is it fine to leave off the Turbo Boost and SpeedStep to just run it at 4.0 GHz constantly?
