4.5 Pretty poor... I was expecting a lot more for the money EternalEmpire | 20/06/2009 | See all EternalEmpire's reviews (6) It doesn't perform the task required of it. Laptop still gets very hot... the only thing this cooler seems to be able to cool is itself. There is only one central fan and it is pretty weak and fails to deliver a powerful stream of cold/cool air onto the laptop. It is also a pretty noisy device. The knob to control the rpm of the fan is very fiddly; it is placed on the side of cooler which makes it very easy to nudge.You can get a lot better for the money.
