Although my macbook has worked great for me since I bought it around a year ago, every single time I opened several applications at once the laptop became really warm. That's why I started looking at alternatives and found a quite new device to help cool the laptop off.
As usual, Amazon worked great and I decided to buy a Logitech N100 cooler . I just got it yesterday (from Amazon.uk this time since Amazon.com did not ship the product outside of the US) and so far so good. It is quiet and it does the job.
