review Frostytech will be testing a low profile Intel socket 775/1366 heatsink
that is ideal for 2U hight small formfactor PCs and media center
microATX-style cases. Finding a good heatsink for a height limited PC case
has always been a challenge, so do bookmark Frostytech Top
5 low profile heatsink chart.
The Evercool HPK-10025EA heatsink uses
a simple arrangement of swagged aluminum fins over four 6mm diameter copper heatpipes, connected by a short distance to the CPU. The entire heatsink stands 65mm tall and weighs a feathery 320 grams. The four heatpipes are
exposed at the base of the heatsink, which although now a common technique is
a first for such a low profile heatsink. The stubby aluminum fins
rest below an Arctic Cooling style, red 110mm
fan that rotates at a moderately audible 1800RPM.
The Evercool HPK-10025EA heatsink accomodates Intel socket 775 Core 2
Duo and socket 1366 Core i7 processors only. The heatsink requires access to the
rear of the motherboard and a phillips screwdriver
to install. Retail price is estimated at $22. As of
this writing mounting brackets for LGA1156 Intel Core i5 processors are not available.

The heatsink has a pair of stainless steel mounting bracket attached to
the base. To install it the motherboard will need to be removed so screws (with non-scratch washers) can be installed
from the opposite side. This approach does makes getting at the
CPU later on a rather involved process, but with microATX systems it shouldn't
be too much of a hassle.
Base Finish and Flatness
Flipping a heatsink over to inspect the business
end is often a simple indicator of overall cooler quality. More practically
speaking, a heatsink is in many ways only as effective as the contact it makes
with the processor - the flatter and smoother the better. Base finish is one of
the criteria that Frostytech measure in the course of evaluating heatsinks, and
it involves two distinct aspects. Surface Finish is the first; this is
calculated with the aid of Surface Roughness Comparator that has a cross section
of common machine surface finishes and their numerical surface roughness
equivalents in microinches. The second is Surface Flatness. This is tested with
an engineers straight edge or proven flat surface, in two axis.
The base of
the Evercool HPK-10025EA heatsink has
a surface roughness of approximately 16
microinches, which is considered good. The base is machined perfectly flat in
both axis and the copper and aluminum parts are flush. Sometimes after the machine
step the parts can change orientation or move around.
The copper heatpipes appear rather thin where the
machining has occurred, so be careful not to puncture the soft metal with
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!
