II. Installation of the cooling components
Placement of the cooling components may vary depending on your chassis and motherboard configurations. A mock-up installation is thus
necessary to estimate the length of the different sections of tubing that will be required between each component.
The following is the recommended sequence of components installation.
1. Radiator and fan
2. Water-block(s)
3.
Pump and reservoir assembly
1. MCR120-F R ADIATOR INSTALLATION
The MCR120-F  ships with the fan pre-assembled to the radiator. It has
been configured so that the fan will draw fresh air from outside of the
chassis. This configuration is preferred to optimize cooling of the CPU.
In effect, if the fan flow direction were reversed, it would use heated air
from inside of the chassis, which is usually 3
°C (at best) and up to 10°C
hotter than that of the ambient air outside of the chassis. Under these
conditions, when installing the radiator at the back of the chassis, ensure
that the fan located at the front of the chassis, is in exhaust mode
(blowing air out). When installing the radiator at the front of the chassis,
there is usually no need to change the airflow direction of the fan located
at the back of the chassis as it is usually already set up in exhaust mode.
Installation
Depending where a 120mm fan opening is available, the MCR120-F 
can be installed as shown in Figure 1 (back of the chassis), or Figure 2
(front of the chassis). Due to the wide variety of chassis configurations,
Swiftech cannot guarantee that this assembly will bolt into any chassis
without some modifications. However, an external mounting solution is
available in option with the
MCB120  “Radbox” which will usually allow a
plug-and-play installation with most desktop computers. Please refer to
the MCB120 “Radbox” installation guide in appendix.
Bleeding
For bleeding purposes, the preferred radiator orientation is with inlet and
outlet pointing up as shown in figures 1 and 2. The radiator may be
permanently fastened to the case when it is installed in this position.
The radiator can also be installed at 90 ° or 180°. During the filling
process however, you will need to rotate the radiator back upwards
in order to allow the air trapped inside to escape. For this reason, it is
recommended to fasten the radiator to the chassis only after the circuit
has been fully filled and bled in these configurations.
Tube installation
The MCR120 features built-in 3/8” hose barbs. All you need to do is to
slip the tube over the barb, and secure it with the provided hose clamps.
Electrical connection
The fan shipped with the MCR120 uses a 3-pin connector. For 12volt
operations, this connector can be safely installed on one of the
motherboard headers. Use any free header other than the CPU fan
header, since the pump RPM sensor will be connected to the CPU fan
header in order to monitor the pump.
For low noise operations, 2 additional fan connector adapters are
supplied with the kit, and should be connected to the power supply
instead of a motherboard fan header:
12v to 7v adapter: this setting provides a good
balance for performance, at whisper quiet operations
12v to 5v adapter: this setting is for silent
operations, and non-overclocked processors.
