Although I've rated 5 stars there is something to verbessern.Der cooler comes with a Y-cable for connection (2 USB connector on the notebook 1 mini-USB connector on the cooler) where the mini-USB connector dangerously behind the radiator is far out and easy kann.Die be damaged most laptops have the USB ports on the side. So the terminal and control board on the side would have been better so you do not have to run around every side of all the cable unit and if already then were angled plug angesagt.An the site would also be easier to operate and plugging. Also, it should for the relatively high price give a power supply to (but is optional) One has the USB port connectors in the BIOS and in Windows to power so that the fan runs (was at least for me so) .Ansonsten the device but worth every penny Value !!! - looks cool -Is well finished -Kühlleistung is good-is big enough for my 15.6 inch Notebook (17 inches would go) -Is really quiet -Is easily -Has a 3x USB Hub
