Abstract: Like almost every Arkua heatsink, the main secret of their ability to cool is a central copper core.

||The Fan: |
good little fan grill protects both fingers and the fan from damage. 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.
The core of the 6258 is a 29mm diameter
copper slug. The plastic fan shroud that surrounds the upper layer holds
the fan about 7mm above the tips of the heatsinks
fins. Since the heatsink is so short it really isn't needed much for directed airflow. 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. The dot on
the clip ensures that pressure is applied over the core of the
processor, and not off to one side.
The clip design works a heck of a
lot better than the original Thermosonic coolers ever did, and doesn't have a tendency to get stuck
on the fins. The clip requires the use of a flat head screw driver, but
is pretty easy to engage, and holds the entire unit securely. The entire heatsink is only about 58mm

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, while being curved outward as
This is the base of the Arkua 6258, and it does look
rather spiffy. The star pattern fin design works efficiently to move heat away from
the processor as downward air keeps everything cooled. The base is machined perfectly flat and
is very smooth, though not polished. The copper core is 29mm in diameter. The
base is undercut 2mm to allow clearance for the socket cam arm.
