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. The heatsink is compact in size, and weighs a
feathery 341 grams. The Igloo 5062 Cu Light ships with a pre-applied patch
of high viscosity thermal compound applied to its base which is a nice
touch.
The real
question of the day is whether a 28mm diameter copper slug at the bottom of
this Glacialtech heatsink can actually improve it. If done right, the copper
insert will conduct heat from the processor up the surrounding
aluminum fins and on towards the surrounding air mass more efficiently than the solid-aluminum
Igloo 5057 E model.

If you've been reading Frostytech in search of your next
quieter/cooler Intel heatsink, you've no doubt read our reviews of the stock Pentium D and Core 2 Duo heatsinks.
Looking at the Glacialtech Igloo 5062
Cu Light we notice one glaring difference in how this heatsink is built, compared
to those Intel models. It's the copper slug you see.
In Intel's iterations, the copper slug
is solid at the base, and formed like a cup up towards the top.
This allows heat to be conducted towards the upper edge of the aluminum section without
suffering from excess metal unnecessary storing heat energy behind the fan motor. Glacialtech has taken a
different route, opting for a solid cylindrical block about 25mm thick.
That leaves 16.5mm of
aluminum not in direct contact with the copper, whose job is to quickly conduct
heat from the CPU to a larger surface area. Since this isn't happening,
heat is conducted up along the aluminum fins, and around the copper
cylinder in areas that vary from 1.7mm thick to 7mm thick. There's more to
it than this, but let's wait until the synthetic thermal test results are in.
FrostyTech's Test Methodologies are outlined in detail
here if you care to know what equipment is used, and the parameters under
which the tests are conducted. Now let's move forward and take a closer look at
this heatsink, its acoustic characteristics, and of course its performance in
the thermal tests!
