Want to know what heatsink AMD relies on for its socket AM2
Athlon64 FX and Athlon64 X2 reference platforms? The
AVC Z7U7414001 heatsink. While this cooler certainly lacks a catchy name, for
an OEM heatsink it packs a big punch in a little package. The AVC
thermally responsive fan enables the heatsink to automatically adjust its fan
speed as ambient case temperature dictates, thus decreasing noise output as much
as possible. While running quietly, the AVC Z7U7414001 is a mainstream cooling
solution, but when its 70mm fan spins to full speed, the Z7U7414001 is one of the
most effective Athlon64 heatsinks Frostytech has tested for the socket 939 or
socket AM2 platforms.
As this is one of the very
first socket AM2 (aka socket M2) heatsinks to enter the FrostyTech test labs,
we'll be touching upon the critical differences between 940-pin socket AM2 and
socket 754/939/940 heatsinks in just a moment. The Z7U7414001 heatsink is fairly
compact, and weighs but a little over 440grams, but its four copper heatpipes
and thin aluminum fins work together in a very efficient manner.
heatsink comes with a pre-applied square of SC-5022 thermal compound on the base and little
else. The single tab clip mechanism makes it compatible with both socket AM2
and socket 939 processor heatsink retention frames.

Corporation (AVC) itself is one the largest heatsink manufacturers in the
industry, but primarily so in an OEM capacity. The company produces several
models of stock Intel and AMD heatsinks, in addition to a variety of after
market models. In our experience, AVC's heatsinks are designed and built with
reliability and cost in mind, so they perform well at a generally affordable
The AVC Z7U7414001 heatsink relies upon a set of four
heatpipes that connect the copper base to different portions of the aluminum
fins, at different heights. The intention of this is to transfer heat from the copper base not only via the fins, but with the aide of the copper heat pipes to sections of the heatsink
that are out of range for purely conductive forces.
Testing this heatsink was a
little tricky, because of the thermistor tied into the fan motor. It adjusts the speed of the impeller based
on the ambient air temperature, and so we had to short out those contacts to push
the AVC Z7U7414001 heatsink into its maximum operating speed.
Next, we'll examine the new AMD
Athlon64 socket AM2 heatsink retention frame and discuss which kinds of socket 754/939/940 heatsinks
have been made obsolete by its four-post screw design.

new socket AM2 heatsink retention frame and explain which kinds of K8 heatsinks
are not going to be compatible with it...
