System Overclocking Newbie

[SilvixHD]

What can/can't I over clock?

Processor: Intel Core 2 Quad Q9400 @2.66GHz

Graphics: ATI Radeon HD 4350

Motherboard: ASUSTek (P5QL/EPU Model)

I unfortunately don't know what kind of fan I'm using. I recently bough this computer for a steal of 140$ and was wondering what it's maximum capabilities were, and if it was a good idea to overclock.

Thanks in advance for the help!

you need to know what cooler it is, if not then you risk burning up the processor.

Is there an application I can download that will tell me what kind of fan I am running? Or do i have to rip the thing apart to find out?
