Also, if you can't be bothered to get a cooler just having a couple of coasters under the two back corners of your laptop so it is a couple of inches off any surface makes the world of difference. My CPU is 3 years old and overheats and crashes after 20/30 mins of fm when the laptop is flat but I can play for hours with no overheating or crashes by just sticking some coasters under the laptop to lift the back end up a bit.
