"Made by the Taiwanese thermal solutions company Glacialtech , the Igloo 5610 Plus Silent is a straightforward, economical dual fan heatsink for Intel socket 775/1366 and AMD socket 939/AM2/AM3 processors. The heatsink stands a modest 139mm tall, weighs 780 grams and is built around two copper heatpipes and slim tower of raw aluminum fins. Like several other Glacialtech heatsinks, the Igloo 5610 Plus Silent has scalloped leading edges on the aluminum fins to help break up laminar air flow and decrease back pressure."
