The
aluminum fins on this tower heatsink are 0.2mm thick, allowing air to easily pass through the
fin stack and consequently keep noise levels
in check. The single 140mm PWM fan on the Igloo H58 heatsink rocks out at 1400
RPM full blast, just 700 RPM when dialed back to its most conservative
speed. Noise levels flutter between 46.4-31.0 dBA according to Frostytech's real world sound measurements
- ie. it's nice and quiet. Standing 174mm tall, the Glacialtech
Igloo H58 heatsink ships with the one aforementioned 140mm PWM fan but
can accommodate a second rear-mounted fan as extra clips are included. Two fans are handy
if you prefer to run both fans at very slow RPM. Weighing in at 840 grams, the Glacialtech Igloo H58
heatsink installs onto Intel socket
775/1155/1156/1366 and AMD
socket AM2/AM3/FM1 processors. Retail price is
estimated at $34 through the usual
heat sink retailers. As of this review, LGA2011
is not supported.

Exposed heatpipe base heatsinks are pretty common these days, but not every CPU cooler
that has them is made properly. Manufacturing an exposed heatpipe base heatsink is trickier than it first appears , the heatsink maker has to;
1) Keep the flat part of the heatpipes even with one another after repeated heating and cooling cycles. 2)
Choose just the right channel profile (circle, oval, egg-shape, flattened circle, flattened oval, etc. to swage the heatpipes into the aluminum so nothing shifts around. 3) Not damage the internal wick structure.
Then there's the radius of the heat pipe bend -
one manufacturer at Computex quoted a loss of 30% total heatpipe heat
capacity for every 90 degree bend!
Glacialtech
have nice soft bends in the heatpipes and the deformation of the heatpipes in the aluminum swage
block isn't very strong (that's good). Heatpipe spacing is wide, but the gaps don't
concern us at Frostytech. Gaps are rather useful for squeezing away excess thermal compound.
Heatsink Mounting Hardware
The Glacialtech Igloo
H58 heatsink ships with one rear motherboard support bracket that fits most CPU sockets on
the market right now. Separate metal brackets are provided for Intel
or AMD platforms that attach to the aluminum plate on the bottom
of the heatsink.
The Intel
socket 775/1155/1156/1366 mounting bracket
accommodates the full gamut of Intel processors
except LGA2011. The brackets screws onto the motherboard with collared screws and
a little wrench.
For AMD motherboards, Glacialtech use metal
brackets which support AMD socket AM2/AM3/FM1 processors. These screw into
the common motherboard support plate supplied with the heatsink.
The instruction manual is clear and easy to understand. You will need
access to the rear of the motherboard to install this heatsink, we'd recommend taking the
board out of the case for easier access. Four wire fan mounting clips
are supplied along with Glacialtech's IceTherm II thermal interface material.
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!
