I heard that overclocking reduces your computers life span but I was wondering how much because Ima build a new computer soon and I'm planning on overclocking the e8400 3.0ghz processor. Also, how much cooling would I need to overclock it to about 4ghz? The case I'm getting has 2 big 240mm fans on the side of the computer but I'm not sure if itll be enough since I'm new to building and overclocking.
