Design and Features

The Silent Square is a rather simple tower-like cooler whose aluminum heatsink is fastened on five heat pipes about 6mm in diameter:

There are 2 x 37 thin aluminum plates in this heatsink. ASUS engineers think the step-like shape of the ribs not only increases the dissipation area but also directs the airflow from the cooler?s heatsink to the mainboard components and power circuits that need cooling, too.

Besides that, there is a metal bar in between the heatsink ribs. It is tilted downwards and serves the same purpose:

The heatsink is covered with a metal casing on the top and sides. Moreover, the sides of the aluminum ribs are curved in so that the air couldn?t leave the heatsink there.

This helps fully utilize the airflow created by the fan.
