Overclocking an AMD 3800 x2

Hi,

I have an AMD 3800 dual core and wondered how to go about overclocking it. I have the stock fan that came with the processor, is that sufficient or should I upgrade the fan and heatsink?

Is there any specific software that I should be using to overclock and how should I go about it without damaging the cpu? :)

 Cheers,
