CPU Temperature

Those are good temperatures, but they will move up as you start to overclock and they are also dependent on the ambient temperature.

No one can say "how high should I go". There are too many variables---voltage, ambient temperature, which particular i5 you have, the cooler you have, your prior overclocking experience, how much time you are willing to spend on learning, how much money you can spend for better cooling solutions, how much it would matter if your PC crashes, whether or not the PC is used for anything important rather than just "playing", etcetera, etcetera.

Voltage is a critical factor.

There are dozens and dozens of Internet sites devoted to overclocking. I'd suggest you start there and start learning, rather than expect some easy answers.

Definitely, I will learn how to overclock on my own I just wanted an expert's opinion on weather I should do it or not.
The CPU is: Inter Core i5-3470 @3.2Ghz and the cooling process is made by 5 fans so no fancy liquid.

Nearly all overclockers do it as a hobby of some type.

With the speed of modern processors like the i5-3470, there's very little reason to overclock just for the speed advantage--unlike 15 years ago when processors were quite weak for most purposes. For that reason, a lot of people that used to overclock have given it up.

How much does it matter to you if your PC completes a certain task in 50 seconds rather than 60? Or in .00015 of a second rather than .00018? Probably doesn't matter at all---aside from the hobby aspect or unless there is a direct financial payoff---like you are getting paid for how quickly your PC can do something. Maybe you can do something 100 times a day overclocked and only 80 times a day not overclocked and you are getting paid a dollar for each something.

It takes time, money, learning, and constant attention to voltages and temperatures--all good reasons why businesses don't do it and why you shouldn't do it if your PC is used for anything critical.

You'd likely need a new CPU cooler to get very far. The stock Intel cooler is very good for normal purposes at stock clocks as long as you don't care about the noise it produces.

Hi,
It doesn't look like a K series processor so oc'ing it might be risky and shorten it's life :/

You should never overclock what you can't afford to replace.

Just some food for thought. :)

A non K cpu can not be OCd

Or so they say.

But you could go into the bios and have all the cores Turbo up to 3.6 GHz, if your bios allows you to.
