Is a stock CPU cooler inside the CPU you buy good enough to cool it? I plan on building a new computer but i'm not sure if I need to buy a CPU Cooler, i'm not going to overclock or anything.
The stock cooler keeps your CPU cool enough. Some people complain about it being a bit noisy (especially Intel). I dunno, I've never heard the stock cooler :P
But adding an aftermarket cooler will allow you to keep the CPU even cooler, which probably will prolong its lifetime. I dunno by how much though. You should probably stick with the stock cooler, or a cheap cooler like the 212 for possible future OC'ing.
