Glacialtech Igloo 5062 Cu Light Heatsink Review
Glacialtech Igloo 5062 Cu Light Heatsink Review
Abstract: The real question of the day is whether a 28mm diameter copper slug at the bottom of this Glacialtech heatsink can actually improve it.

Information on Frostytech's test methodology is available here.

The Heatsink Fan:
The 25x80x80mm fan spins at a fixed 2000RPM, and is not PWM or thermally responsive. Power is supplied by a standard 3-pin motherboard fan header. The seven bladed impeller is not protected by a fan grill.

Heatsink Top:
At the center of the extruded aluminum fins is a 28.8mm diameter copper slug. This cylinder of copper stops 16mm short of the top of the heatsink body, which is 36mm thick. The walls of the central aluminum "block" range from ~2-7mm thick, so thermal conduction is apt to be constrained in some areas. Each aluminum fin is 0.5mm thick and radiates out ~29mm from the center. The thin fins are spaced about 0.8mm at the base, nearly 3mm at the tips.

Heatsink Side A:
Standing 70mm high, the Glacialtech Igloo 5062 Cu Light uses a tool-free clipping system. The clip locks into the PCB holes which surround the LGA775 Intel processor socket.

Heatsink Side B:
The fan attaches at four points to little flanges which are outside the main body of the heatsink. The clips are attached to two steel brackets which are screwed into the body of the Glacialtech Igloo 5062 Cu Light heatsink. Brackets for other CPU sockets are not included.

Heatsink Base:
The base of the Glacialtech Igloo 5062 Cu Light heatsink is machined perfectly flat in both axis. A patch of grey thermal compound is applied by the manufacturer to the copper base which is exactly 28mm in diameter. Surface roughness is equivalent to ~16 microinches, which is considered excellent.
