There are devices you can purchase which aids in pulling more air through the system and keeping it cooler. One which I purchased and am quite pleased with is by Antec. It is a dual fan unit that is powered by one of your USB ports. You place your laptop on top of the unit, power it on, and it works wonders at keeping your system free from damaging heat buildup and those annoying shutdowns!

There are other units made by other manufacturers available as well. Some more expensive, some less. I have always had good luck with products from Antec and their price was reasonable as well.

Please you can see an expert to open the laptop and see to the cooling fans.

Just tell him you want him to confirm if the cooling fan is up-right or it needs a replacement so he would not charge you much knowing you are aware of your need.

Cheers.
