How to keep your laptop from overheating
Elevate the laptop.
Put a small book or item (like the docking station for your ipod) under your computer's battery when sitting at your desk. This slight tilt allows a lot more air to flow under the laptop, keeping it significantly cooler.
Ensure that the book is not blocking the bottom fan hole. If a book doesn't help, you can try something more uneven.
