The Rosewill Notebook Cooler did what it said it would do and that is to lower the temperatures of a laptop. While the temperature drop wasn't as high at idle, the Rosewill really shined through in the load temperatures. The ergonomic tilt feature provided a comfortable base for me, but might not be something you would like if you enjoy flat keyboards instead. Another nice thing about the Rosewill is that a non powered USB port can power the fans as they only pull 250mA.
