content: I've got two dual core laptops at home that I remotely run virtual images on and they tend to get rather hot with the lids closed. Putting a Chill Pad under each laptop keeps both of them much cooler. I don't hear the internal fan in the laptops firing up anywhere near as much. I did have to turn the Chill Pad sideways for one of the laptops to align the fan vents with the laptop heat vents but it works fine in that configuration. If I pick the laptop up and put it back on the Chill Pad the fan inside may start to spin off balance. You have to turn it off and then spin it back up. Overall a great deal for heat venting needs.
