Glacialtech Igloo 5620 PWM Heatsink Review
Glacialtech Igloo 5620 PWM Heatsink Review
Abstract: While the Igloo 5620 PWM heatsink ships with one 92mm fan capable of operating at 2300-800RPM, additional fan clips are supplied for a second user-supplied 92mm fan to be installed if desired. The base of the heatsink makes use of exposed heatpipes to leverage the rapid heat conduction qualities of these thermal devices.

Information on Frostytech's test methodology is available here.

The 92mm fan on Glacialtech's Igloo 5620 PWM heatsink spins at 2300RPM by default, going as slow as 800RPM. Power is supplied by one 4-pin PWM motherboard fan header. The Igloo 5620 PWM heatsink stands 133mm tall and is ~100mm wide including the extra space the fan brackets occupy. Just two 6mm diameter sintered metal wick heatpipes are used to conduct heat energy from the base to the 91mm tall aluminum fin stack.

Each aluminum fin on the Igloo 5620 PWM heatsink measures is 0.3mm thick and spaced 1.5mm apart. There is a very small 1.7mm plenum behind the fan. Clearance below the lowest fin is 33mm to the top of the CPU.

Two 6mm diameter copper heatpipes pass through the aluminum fins at the outside edge of the fin stack. At the base the heatpipes are spaced 4.5mm apart and swaged into a 7.5mm thick aluminum extrusion. The narrow mounting surface measures 36x26mm.

Next up Frostytech measures the sound output from the Glacialtech Igloo 5610 Plus Silent heatsink with its fan running at full speed...
