my laptop has 3 fans underneath it and one on the side the three on the bottom are covered by my cooling pad and keeping really cool but the one on the side isnt how should i keep it cool?
As long as your CPU and GPU aren't getting too hot, you should be fine and it shouldn't really matter. Download Speed Fan :http://www.almico.com/speedfan.php or another similar program to monitor your temps and let me know how hot it is.
Actually, the one on the side is the exhaust - warm air should be blowing out of it. Nothing to be concerned about as long as you can feel warm air from 3-4" away from the side fan - means it's working good.
