"Targus Chill Mat proves very effective!!"4.0 starson by carmelcrew
Pros: Light weight, quiet, very effective.
Cons: Requires laptop USB port to run. A battery powered mat would have seemed much more appropriate if you are looking to limit laptop battery consumption.
Summary: I have a Sony Vaio SZ laptop that runs very hot after a few hours of use. The fairly loud internal fan would blow very hot air and a decrease in laptop speed and battery efficiency was observed. The targus chill mat quietly cools the laptop and more importantly, the laptop maintains a cool core temp so that the internal fan is never needed. I would have liked a battery powered mat to extend my laptop battery life but it isn't that much of an issue. Bottom Line: If you want to extend the life of your laptop then you should get a Targus cooling mat!
