3 ventilos to their lowest position make almost no noise. A middle position they remain at the same volume level as the noise of the fan on my laptop when it is in low / medium business. At full sound noise is honorable and does not disturb when we play for example.
The possibility of repositioning the 3 ventilos independently on the whole surface allows for effective cooling of the cell according to its own hot spots. Goal achieved!
A good point is the possibility of storing the cooler in passive mode with my netbook, an ASUS K75 VM-19 "16/9 that right. Well done lodge.
Finally I served as a "station" to "mansion" with incline and the angle is OK for convenient typing, I can pass underneath unsightly cables (network, USB hub, power supply, second screen, etc. - provide still serves the cable).
Another good point is the power splitter / USB connectivity, which lets not lose a USB port for "nothing". As being "remains", the connection is on my USB hub in lieu of a port on my laptop.
I am satisfied with this laptop cooler off.
