|Arkua 848X-6B Heatsink From All
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

Take one heatsink, sliced it 12mm thick, and insert a

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

There are no external clipping mechanisms on the heatsink, just those four

the lightest heatsinks we have come across which is intended for
use on the Pentium 4 processor of up to 2.2GHz.
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.
