Due to the very different reviews on different Cooling Pads, I was at first inspection table, if they ever get that and also not too loud. My fears were also reflected in the ratings of the previous model of Logitch Cooling Pads. That's why I decided to simply try out the new pad and I must say I'm surprised postiv. The ventilation / cooling functioning properly due to the grooves / channels and one does not hear the fan. The fan on my laptop is louder by far. Recommended !!!
