I don't think you will be successful, you will most likely kill the chip. It isn't as simple as just heating with a lighter or flat iron, you MUST watch your temperatures, I would not go further than 160c...

Anyway, why would you do such a thing? You won't gain any overclock headroom, and temperature difference will be very minimal, maybe even unnoticeable.
Unless you got an IVY.
