The Glacialtech Igloo 5062 Cu Light is a socket 775 cooler for Intel Pentium D, Core 2 Duo and Celeron processors.
"Unlike the Igloo 5057 E model Frostytech tested recently, this heatsink has a copper insert at the base which may give it an extra edge. Made by Taiwanese heatsink manufacturer Glacialtech, the Igloo 5062 Cu Light is otherwise a low noise heatsink patterned after the stock Intel radial fin solution.
Yet where the stock Intel LGA775 heatsink has a bigger fan, the Igloo 5062 Cu Light is equipped with an 80mm vaneaxial fan that spins at a fixed 2000RPM. This allows the Igloo 5062 Cu to operate quietly under power, generating about 45 dBA according to Frostytech's sound meter."
