The Glacialtech Igloo 5610 Silent heatsink is a pretty straightforward CPU cooler. Only after removing the 80mm fan do we see one of its unique qualities - scalloped cooling fins. Seen from the top down, the leading edge of each aluminum fin has a little wavy pattern punched out of it. This helps break up laminar air flow and decrease back pressure as the air exits the fan and proceeds through the array of aluminum cooling fins which are press-fit around the heatpipes. The heatpipes are soldered to the copper base, but not each individual aluminum fin.
