Overclocking 3 Ghz to 3.16 GHz?

Be careful overclocking, and honestly, you wouldn't know the difference from 3Ghz to 3.16Ghz in any application. But if you REALLY are tempted, the slight increase would probably not affect the temperature by more than a few degrees Celsius. I suggest getting a program to monitor the temperature AND stability for an hour or so after overclocking to ensure the temperature is comfortable. Run a variety of programs, games, internet, etc to simulate daily activities to make sure you don't have any odd crashes or other issues.

As a side note, most modern processors will automatically power down the system if the temperature hits the 'red zone' anyway, so you shouldn't be in too much trouble. If you overclock anymore than that, I would strongly suggest a different fan or water cooling all together.

First of all, you need a good motherboard, if its an asus or gigabyte then you'll be able to overclock more. Also I recommend a better cpu cooler (I you already have one then your set).

You should never even mounted your stock intel fan. They are horrible and you will destroy your processor if you overclock.
