The big fan provides a very satisfactory amount of air compared to the noise it produces (with ventilos Inevitably, bigger is, the less it's hot!).
The grid of metal vent allows air to circulate properly even when the computer is placed on a bed, and from an aesthetic point of view it is much more pleasant.
Do not forget the USB port which is still usable even when the cooler is connected.
In short I recommend this product without restrictions!
