Hi, I'm new to overclocking so any help will be appreciated. I have a prebuilt PC with an FX-6350 i want to overclock. Stock speed is 3.9 GHz. The thing is, do I need to buy a new heatsink? Mine came with a copper heatsink, but I heard stock coolers aren't recommended for overclocking. I don't know how far I want to overclock, maybe to 4.2 GHz?
Thanks!
