ASUS have just released a new badass cooler into the market dubbed the Arctic Square. It boasts a number of nice features such as double side fines, dynamic fan speed control and multiple heat pipes for efficient heat dissipation; and for added bling they've whacked a subtle blue LED into it as well.
For more info on it have a read of ASUS's PR here folks.
The Arctic Square incorporates a double side fin design that includes "ladder-shaped" fins located on both sides of the cooler for a larger heat exchange area. Four heat pipes made of copper efficiently transfer heat generated by the CPU to the fins, maintaining processor temperature at levels most suitable for high-performance and stable computing. Designed to have a smaller size, the Arctic Square is compatible to many motherboards and chassis - providing reliable PC operating systems.
