Abstract: Vantec's entire socket 478 heatsink weighs in at 472grams, and interestingly enough, gets by with just a 70mm fan; odd since 80mm fans are the
standard these days.

||The Fan: |
A plastic fan guard protects fingers and stray objects from the
moderately paced 4000RPM fan below. Chances
are good you'll get slightly better air
flow by removing this for a wire fan grill. The fan
draws power through a standard 3-pin motherboard fan header, and
supports RPM monitoring.
The Vantec Aeroflow2 is remarkably pretty with the fan removed -
the symmetric appearance almost has the look of retro-modern artwork. While it may look cool,
our question revolves around just how well this heatsink actually cools. The 25mm
diameter copper core is in the area of 30mm tall, just
short of the full height of the aluminum section of the heatsink. Each aluminum fin
measures 0.5mm thick at the tip, and 1.0mm thick at the base. The
fins are spaced ~1.0mm apart, and their length varies from just 1mm to 31mm long.
The splines coming out from the center of the heatsink are about 3mm thick
The steel fan shroud holds the fan in place,
about 4mm above the aluminum fins of the heatsink. On either side are little
folds for the clips to fit into, and hold the entire heatsink in place on the socket.
The Aeroflow 2 stands about 73mm tall, meaning it should fit in most compact cases without
The aluminum fins appear to
slope into the heatsink, but this is simply the way the body has been extruded.
The splines which come off at an angle are there to bite into the exhaust air
from the fan, and improve cooling. Other companies have taken to curving the fins for the same
The base appears virtually identical to the top of the
Aeroflow2, except for the fact that copper core is just about flush with the surrounding
aluminum. The copper section which comes in
contact with the processor is very flat, and quite smooth.
There are two small 1mm deep recess cuts on the outer 13mm
of fin on either long edge of the
