ok, you have answer the whys how about the hows?
So you over clock for speed, but don't that lead to a hotter unit and I through you wanted to keep temp down. It's like you put a NO2 kit on your car motor, but if you don't rework the lower end,ie crank, you'll blow it up the first time you switch it on. So to keep temps down you water cool the cpu,right?
Hey I'm learning now, so yall keep talking!:)
