I got an Asus N43SL and it's really hot on the left hand side. I can't rest my left hand there for too long, because it's really hot.
The problem probably is its harddisk. And the air vent is there too. When I'm playing games, my hand can somehow feel the heat from the vent. It somehow heats up the upper left area of the keyboard as well. So basically the entire left area is hot (the left palm rest and the left side of the keyboard)
So, how do I reduce the heat?
