Arkua 848X-6B Heatsink From All Angles

The Fans:
This is a very tiny 10mm thick 60mm fan and so the amount of air it can move is relatively small. With space as the deciding factor there are few other options available for active 1U server heatsinks. The fan is held in place with screws onto a rather nicely made stainless steel frame. The fans supports RPM monitoring so that the system can keep track of any potential problems, or stuck fans.

Bare Heatsink:

Take one heatsink, sliced it 12mm thick, and insert a chewy copper core and you have the Arkua 848X. The central copper core is 22mm in diameter and goes all the way through the very thin heatsink. The fins measure 1.5mm on average, and are spaced a healthy 2mm apart. The design is pretty classic, and can be very efficient with the right amount of airflow.

Side A:
The Arkua heatsink is just 12mm thick, and the fan just 10mm. Altogether, the two components measure an absolutely slender 23mm in height. The four screws can be seen here attached to the base support/retention mechanism.

Side B:
There are no external clipping mechanisms on the heatsink, just those four screws to hold it in place. At just 162 grams it is among the lightest heatsinks we have come across which is intended for use on the Pentium 4 processor of up to 2.2GHz.

Heatsink Base:
The base is exactly like the top of the heatsink so we won't have to go into too much detail here. Suffice to say, the base is machined very flat, and is almost mirror smooth.
