| Arkua 7228 Heatsink From
All Angles |
 |
The Fan:
After getting the
top of my finger chopped off in a
Delta fan I'll never look at a fan grill the same
way. Fan grills save fingers! Remember that and you will go far.
The Innovative fan is noisy, but spins around at 6800RPM so the
trade off may be worth the noise. The fan connects to the motherboard fan
header via a 3-pin connector which also supports RPM monitoring. |
 |
Heatsink Top:
The core of the 7228 is actually cut away so
that the copper slug is roughly half the height of the entire fin section. The plastic fan
shroud that surrounds the upper layer holds the fan centered in place, and directs
the airflow down amongst the fins. Each of the aluminum fins is
scalloped to ensure good turbulence, and improved heat transfer. Fins are spaced
2-2.5mm apart and are typically 1mm thick. |
 |
Side A:
The little recess in the fan shroud makes
getting at the clip fool proof, and in fact the clip design works a heck of
a lot better than the original Thermosonic coolers ever did. The clip requires the use of a
flat head screw driver, but is pretty easy to engage, and holds the entire unit
securely. The fan shroud extends down about 24mm, leaving 26mm worth of fin exposed for airflow to exhaust
out from. |
 |
Side B:
The name of the manufacturer is
on the other side of the heatsink, which is identical
to the above side except for the lack of a clip
system. The fins are spaced about 2.5mm apart and are slightly
tapered. |
 |
Heatsink Base:
Marvel in its glory for this is
the Arkua 7228 is what should be written on the box of this
heatsink. The star pattern and fin design works efficiently to move heat away from
the processor as downward air keeps everything nice and cool. The base is machined perfectly
flat and is very smooth, though not polished. The copper core is 24mm in
diameter, and the base undercut to allow clearance for socket cam arms.
