The new Arctic Square heatsink Frostytech is testing out for you today consists of an array of nickel plated aluminum fins wrapped around a 92 mm fan that is set within the body of the heatsink.

It's a simple arrangement of fan and cooling fins, but one that draws cool air into the heatsink and expels warmed air out the other side. Noise never becomes much of an issue with this heatsink because the fan impeller does not rotate more than 2300RPM. Asus's Arctic Square incorporates four nickel plated 6mm diameter copper heatpipes that conduct heat from a copper base to an array of aluminum fins above; a fairly standard orientation these days. The heatsink weighs in at 667grams, and stands 152 mm tall so it is rather a bulky solution that may not fit into all compact microATX computer cases.  You can find Asus' Arctic Square heatsink at most online retailers for $54 USD.
