Should I overclock my CPU?

I am just using AMD Phenom II X4 940 quad processor at A FEW.0 ghz
My typical CPU along with core temps is about 35-40C
What software should i use that will overclock
Can i need to add to the speed of my personal fan/buy the latest fan
What should i overclock for you to (Not planning past A FEW.3)

Over clocking is a “fun” action to take..IF…you are aware of what your doing! you shouldn’t “depend” the OCing.you might find you’ll receive instability long before you begin having crashes.Some CPU’s cant also take the actual mild OC your current planing (3.0 to help 3.3GHz) If you have a very good mother board it might have your “tweaker” while in the bios but you can all of us CPU-Z.Still every one..its not necessarily recommended.

use ones computers bios for you to over-clock
provided that your temps doesn’t reach hot you should not need a much better fan
test this site for over-clock settings and heat.

If they are your inquiries, I suggest you never overclock your components.Do you have any the reason why you wish to overclock apart from just in plain english overclocking.
