So I recently signed up for another computer forums, but was disappointed with the experience I got from it, so I'll try TH out. I'm in the process of building my first computer. It's going to be a budget gaming computer. I went with a Phenom II 965 for a processor. What I want to ask is whether or not an aftermarket fan would be necessary for OCing to maybe 3.8 or 4.0Ghz(stock is 3.4). The only response I got from anyone on the other forum was how aftermarket CPU fans were useless and did nothing. I'd like some more input on this, because I know the Phenom sometimes bottlenecks on stock frequency.
