The most promising physical technological improvements have been, and still are, the implementation of heat pipes. Manufacturers have designed heat pipe specific CPU coolers using various numbers of pipes. Some makers design theirs with only a couple heat pipes while others seem to add as many as they can fit on a CPU cooler. Some look like CPU coolers and others look like engines with copper headers. While all these variations have their own appeal, ASUS has chosen to design coolers with a more isometric feel in their lineup.

We've seen a few of their coolers here at VH before and they were always worthy of recommendations. We have a new one on hand that is actually an updated version of the original Silent Knight CPU Cooler. Today, the Silent Knight II CPU Cooler is on the work bench and looks quite promising.
