The Evercool Buffalo HPFA-10025 is a lower-noise AMD
Athlon64 heatsink for socket 754, 939, 940 and AM2 processors. A fan resembling
the kind used with the Arctic Cooling Freezer 64 Pro heatsink is employed to move air relatively quietly through the
aluminum fins. The Buffalo's fan rotates at a fixed speed of
1800RPM, and is supported from the aluminum fins by four hidden rubber pads.
The idea being that the pads will prevent fan motor vibrations from
transferring to other areas of the heatsink and causing additional noise. The
100mm fan is suspended from the motor to reduce airflow turbulence and noise.
Evercool's Buffalo HPFA-10025 heatsink is made from a simple mix of
"U" shaped copper heatpipes and 60 stacked aluminum fins. A very thin copper sheet is soldered
to the heatpipes at the base, so there is not
a lot of distance for heat to be conducted away from
the processor either - making for one very compact and down-to-business heatsink.
The whole package weighs 500 grams, and
is only AMD Athlon 64 compatible (only AMD mounting hardware supplied).
This goes against the grain with what most other heatsink vendors offer, but I
suppose this allows Evercool to sell the Buffalo heatsink for less... which is
always a positive for consumers.

As you can see
quite clearly from the image below, the AMD mounting clip for the Evercool
Buffalo heatsink is held in position by a small brass peg attached to
the top of the aluminum base block.
The CPU mounting clip uses one, or all three prongs on the two
different styles of AMD heatsink retention frames in use. Clamping pressure is
applied by a small cam at one end, and the clip installs without the use of any
tools whatsoever. There are holes for the Intel mounting hardware to attach to,
but Evercool has cut costs pretty seriously and only included the AMD clip show
here. Another Intel only version of the Evercool Buffalo heatsink is available,
it is the HPFI-10025.
Personally, I think Evercool should have included both
Intel and AMD mounting hardware with the heatsink so consumers can use it on either platform. Marks lost
for excessive cost cutting on that front...
The Evercool Buffalo HPFA-10025 heatsink will be tested on FrostyTech's Intel LGA775 version of the Mk.II
synthetic thermal temperature test platform, and
compared against several reference LGA775 heatsinks. The whole test methodology is outlined in detail
here if you'd like to know what equipment is
used, and the parameters under which the tests are conducted.
let's move forward and take a closer look at this heatsink, its acoustic
characteristics, and of course its thermal performance!
