Laptop Cooling

So I have a Toshiba Qosmio X505. It does gaming fairly well but its starting to show its age with some newer titles. I was looking into over clocking it a bit but wanted to know if a cooling pad is the best cooling device for a laptop or the temperature drop wont be worth the money. If it is, what would you recommend for me? Ive looked on Amazon and seen some fairly nice looking ones that are in the 20-40$ range but not sure if I should jump on it. Hope to hear some advice and thanks in advance!

With my L series I can actually get to the CPU and heatsink and was able to remove it to apply some AS5 which helped the temps.

Well my laptop doesn't sit on my lap. Its on the top shelf of my desk whilei use my 28 & 22 inch monitors below. I was thinkinga cooling pad couldn't hurt the life if the laptop
