I wouldn't even think of overclocking with stock cooling, even if it's just a little bit. You need to have a better cooler on your cpu, and make sure you have adequate cooling in your case as well. At least 1 intake and 1 exhaust fan, 80mm would work but 120mm would probably be preferred. What is your case cooling situation?
CPU's can get hot quick, if you don't have good cooling you will end up damaging or burning up your expensive cpu.
When all else fails...Ham Radio!
I still have the same old HP DV9700T laptop I've had for years...still kickin'
