|Cooljag 2QC/180 Heatsink
From All Angles|
||The Fan: |
The 60mm squirrel
cage fan is small, but for the amount of space available in a 1U server
it is appropriate. The fan is attached to two steel posts which hold it flush against the
fan shroud. There is no space between the base of the fan and the
tips of the fins, and this is important since air is drawn
into the fan through the copper skived fins, before being exhausted outwards. The fan connects via
a 3-pin fan header on the motherboard and supports RPM
With the squirrel cage fan removed we can see that
the copper heatsink is skived in two parts, and each section is 37mm wide.
the main copper fins are 8mm tall, the outer set
on either side, 23mm tall. Note the large holes in each corner used
to screwing the heatsink into place on the PCB.
The copper base of the Cooljag
2QC/180 is 3.5mm thick, giving the cooler an overall height of 27mm. The fins
are spaced 1mm apart and are 0.3mm thick. This is pretty standard for skived
This heatsink is very simple; but makes use
of an extra set of copper fins in the path of the exhausted air
from the fan.
The base of the copper heatsink has been face milled nicely,
and is very smooth, but not necessarily flat from edge-to-edge. The base is
flat on the long side, but slightly concave in the other axis. The curve inward is very shallow, and won't have any major affect when installed.
