As the external unit is an important part, we'll take a more detailed look, describing the internal parts and working.
First we see the built in reservoir. It has one tube incoming, and two outgoing that a few centimeters later are combined trough an inversed Y-split. Two pumps are taking care of the flow.
This bunch of tubes and springs route the flow correctly trough the casing. The unit itself is acting as a radiator, where the cooling liquid goes 3 times trough the casing.
On the rear side we have the in en outlet from the unit, and a power connection, needed to power the two pumps and the led from the thermometer.
Internally we find a molex connector, going from the power plug on the rear side to a little PCB. There the power is divided to the two pumps and de the thermometer, using the classic fan headers. Why Silverstone decided to use a molex connector instead of a fixed connection is not really clear, as there's no need for extra power inside the unit.Installation; some extra details
In the box we found following items:External unit
Water block (+ socket installation + imbus tool)
4 Pieces pre-cut tubing
Power cable from computer case to unit
Two bottles of cooling liquid
PCI rear bracket to pass trough tubing + power
The cooling liquid consists of
Anti freeze agent
Anti corrosion agent
... and has a blue color.
The PCI bracket has decently indicated where to connect what cable or tube. This is also so on the rear side of the unit.
And this is how it should look when installed.
