Summary: I thought this would really help me out since I use a netbook and am always on the go due to my business travel. Since netbooks aren't top drawer in the heat-sink dept anyway, I knew I needed something portable and easy to use. This chill mat did that and was awesome for the first few weeks (I'd say 6 or 7 to be precise); then it all went wrong. First the fans started working intermittently. I had to use an ink pen to nudge them and then they'd turn again fine.
