AVC Z7H2403012 Internal Prism Base Heatsink Review
What is the
newest trend in heatsink thermal design? Hint, it's not heat pipes, prolific
amounts of copper, phase change materials or cold forging - it's the "Internal
Prism Base." If that seems unclear, just imagine that the copper base of the AVC Z7H2403012 heatsink, pictured below, is in the shape of an obtuse triangular prism -
about 67mm long, 13mm high, and 51mm wide. The widest side of this copper prism sits directly on top of the processor core, and the two smaller
sides are soldered to the copper fins above.
Thermalright have been
using a similar process with their
heatsinks for quite some
time, but as their base sections are split down the center
to leave space for the clip, it isn't quite the same concept. The closest
example of the IPB we can compare this AVC heatsink to is the Novasonic-AlCu from Tocools, or the
Thermal Integration TI-A8736N. Tocools
have to be credited with applying the first example of this thermal design technique,
In that adaptation, the heatsink was manufactured
from a solid block of aluminum, and featured a rather tall internal prism shape.
With the AVC Z7H2403012 heatsink, Asia Vital has adapted the
stacked copper fin process, and soldered the fins directly to the upper half of
the solid copper internal prism base.
Assuming the solder joints between the IPB and 45
thin copper fins is good, we should be looking a Pentium 4 heatsink that is a
force to be reckoned with... right?
I tried loosening the screws which hold the aluminum fan shroud in place
so we could get a better look at the IPB inside, but no luck there -
the heads just stripped right off
and wrecked my screwdriver in the process...
Along with the heatsink and
fan, AVC bundle in a set of clips, the socket 478 frame, and the X-Pad motherboard
support frame. Because of the weight of heatsinks these days, and the forces the
clips apply, it is important to support the motherboard PCB from
