Dear oc sifus/forumers, I'm new to OC. Wanna try overclocking my CPU. Below is my pc specs.

Proc : Intel i5 760
Mobo : Asus (can't rmb the model) p7h55 or something liddat.
PSU : Gigabyte 550w (or isit 500w can't rmb)
GPU : MSI 460gtx
Fans all stock. Using CM HAF 922 chasis. Any advice on what voltage? like the clock speed? And do i have to get 3rd party cpu cooler and add some fans here and there? And what speed should i go ?
Really noob at it. Would love to try. =) Appreciate any advice. Can PM me to if all the sifus/forumers are free ya =)
Reason I'm asking all these cause I scare I might fired/blowed my cpu. XD

Thank you in advance.
