Hi, I got a laptop with I3 3120M 2.5 ghz hyperthreading dual core. I need to overclock it to increase my performance in some games. however I am aware I can't afford buying a cooler (I do have money for it but my family thinks it's something stupid to waste money on, PFF) however, I want to know what program can I use to overclock? This is going to be my first time doing it.
