Abstract: The lower amount of air flowing over
the fins impacts its performance level, but also yields a substantial decrease in noise.

| Arkua 6158 Heatsink From
All Angles |
 |
The Fan:
This small fan doesn't really have
enough firepower to keep up with the 25mm version on the 6258, but it is
substantially quieter. The change in fans causes a big drop in performance, but this could be fixed by dropping in a Delta if you
wanted to. The Innovative fan spins around at 4800RPM and connects to the motherboard fan
header via a 3-pin connector which also supports RPM monitoring. |
 |
Heatsink Top:
The core
of the 6158 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 (not shown here). 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. |
 |
Side A:
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 42mm
in height. |
 |
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, while being curved outward as
well. |
 |
Heatsink Base:
This is the base of the Arkua 6158, 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.
