Vantec VA4C7040 Aeroflow Heatsink Review
Aeroflow VAC7040 copper core socket A heatsink is one of the most unique
heatsinks Vantec have produced since we began reviewing heatsinks
in our own FrostyTech way. Retailing for about $32 USD the primarily aluminum heatsink employs several manufacturing principles in its creation with the ultimate goal of potent cooling, and lower noise levels.
the Vantec Aeroflow in my hands proves that the squarish appearance is deceiving - the heatsink
weighs under 400 grams and is lighter than it looks. The bottom of the heatsink appears pretty
solid when you rotate it over, but in actuality, most of the surface of
the heatsink is cooling fin.
Aeroflow uses a TMD fan for cooling because there is more even airflow than with
a traditional brushless DC fan. TMD fans which were
used on several Swiftech models were recalled earlier this year as many of you are
aware. We asked Vantec about this issue in no uncertain terms and were told that
the TMD fans used here do not suffer the same defects. After all, the last thing
we would want to do is review a heatsink that could potentially fry your
processor because of faulty electronics!

The heatsink is built up from a core extrusion which then has
a central cylinder for the copper core bored to the correct
tolerances. With the copper core hydraulically pressed into place, the external
fins of the Aeroflow are cut by a flat saw blade.
Each fin measures under 1mm in thickness, and the base of the fins taper out
as the cut nears the base of the heatsink to help direct exhaust airflow from
the TMD fan (Tip Magnetic Drive).
The idea of the tapered fins seems to be to bring the exhaust air down through the fins and then
out laterally at the base of the heatsink so the air doesn't back pressure
against the motherboard, or processor itself. You should be able to see the
slight taper from the above photo which was taken looking down the heatsink from
the perspective of the fan itself.
