The Akasa
Venom heatsink stands 160mm tall and weighs just over 800grams. It's built around four 8mm diameter
copper heatpipes and raw aluminum cooling fins. The Venom ships with a
fancy nuclear yellow fan called the 'S-Flow' that spins at 600-1900RPM,
moving around 83CFM according to the manufacturer. A single fan is all the Venom heatsink really
needs, but Akasa have provided mount points and additional rubber vibration absorbing mounting posts
for a second fan if you wish to install one on
each side.
Akasa's Venom heatsink installs
onto Intel socket 775/1155/1156/1366 and AMD socket 754/939/940/AM2/AM3
processors. It retails for in the region of $60USD through the usual
suspects.

Exposed
heatpipe heatsinks are great for the larger CPUs entering the marketplace; the
AMD CPU family and Intel Core i7's in particular. The smaller Core 2 Duo / Core
i5 processors don't cover all four heatpipes on the Venom heatsink
in actuality. The outer two heatpipes may not work to optimal levels, while the
inner two 8mm diameter heatpipes may be tasked with the majority of heat conduction.

The S-FLOW fan, apart from
sounding like a plumbing tool, features hydro dynamic bearings and CFD-designed impeller blades which are
supposed to direct more airflow into a centralized vortex behind the
fan. A nifty graphic comparing the S-Flow to an unnamed "Normal blade"
fan drives the point home as only dimensionless graphics can.

The rubber vibration absorbing posts are long enough to easily thread through both holes in the fan
frame - an problem a great many thermal solutions manufacturers overlook. The rubber vibration absorbing posts
slide into a cylindrical groove punched from the aluminum fins. The fit is loose enough that
the fan is easily removable for installation, but not so loose as to work
free thereafter.
Heatsink Mounting Hardware
Akasa's
Venom heatsink ships with brackets for Intel LGA775/1156/1366 and
AMD AM2/AM3 processors. The heatsink mounts to Intel and AMD motherboards
using separate metal brackets that attach to the bottom of the
heatsink and mesh with a metal rear-motherboard support plate. The hardware
is a little more complicated than we typically like to see, but once
installed the heatsink should be firmly held in place. You may need to remove the
motherboard from the computer case to install the Venom
heatsink, thereafter swapping out CPUs can be accomplished with the rear support
plate in situ.
A collection of plates, brackets
and thumb screws accompany the eight rubber fan posts which are supplied
with the Akasa Venom heatsink.

which the tests are conducted. Now let's move forward and take a closer look at
this heatsink, its acoustic characteristics, and of course its performance in
the thermal tests!
