This Cooling Pad Logitech has delivered the usual high quality. The pad, which has a very large fan is operated via a USB connection and has 2 speeds. The first stage is perfectly adequate for a very efficient cooling and barely audible. The otherwise red-hot notebook is even in continuous operation at the bottom colder than when it is off. The otherwise too hot airflow flowing out of the air vent of the notebook, is also slightly cooling.
The 2nd fan stage can be heard loud, I do not need, however, since the 1st stage cools sufficiently.
My 15 "notebook with 16: 9 screen fits neatly over this pad, as if it were made for the manufacturer's instructions - suited to 16." - I would not confirm.
Conclusion: strong buy recommendation
