time, it is also a good practice to setup an alarm temperature,
which will shut down the computer in case the CPU
overheats. Such alarm/shut down process should be tested
as functional.
WARNING!
Wires from the thermoelectric module do get
hot (this is normal). Make sure that the wires do not
touch devices that are heat sensitive, such as vinyl tubes
for example. Heat from the wires may cause the vinyl to
deform, and/or burst.
b. Connecting to your computer power supply:
Important Warning: to connect the MCW5002-64T
cooler
to an ATX computer power supply, you must carefully
consider the existing requirements of other devices
connected on the +12V line. Connecting to an underpowered
unit will definitely damage the power supply.
Minimum requirements for an ATX computer power supply:
36A at +12V in a typical computer setup.
When you connect the MCW5002-64T
to an ATX power
supply, you need to cut the wiring to one of the power supply
Molex connectors, and use a different connector between
power supply, and thermoelectric. This is because Molex
connectors are not rated for 18Amps current, and may
overheat.
c. Connecting TEC wires to the power supply:
Use the provided euro-style wire connector
as shown in fig 11 below, or a similar device
with a current rating of at least 25 amps.
Connect red wire from TEC module to +12V of
P/S (Yellow wire), and black wire to black
wire:
Figure 11
If you need wiring extensions: use 16 gage stranded wire.
Connect the extension to the existing wires with terminal
splices, or solder the butts, and insulate with shrink tubing.
3. Hydraulic
Installation
The MCW5002-64T is shipped with ½” barb to 3/8” NPT nylon fittings. These fittings should be installed using Teflon
tape or plumbers “goop”. If fittings need to be replaced for a difference tubing size, do not use brass fittings, because
of the galvanic corrosion that will take place between copper or brass and the MCW5002-64T aluminum housing.
Always use nylon fittings.
Inlet and outlet are interchangeable.
Type of Coolant:
For best performance, use 95% distilled water, and 5% Swiftech brand “HydrX” corrosion inhibitor
e “accessories” section).
In all cases, you must use Distilled water and a corrosion inhibitor with the MCW5002 water-block. Regular
automotive anti-freeze is acceptable. Automotive manufacturers recommend that not less than 25% is
used.
NEVER use tap water, even for a short-term test.
Not following the above instructions constitutes misuse (*) of the product, and will void your warranty.
Final inspection: Once the installation is completed, it is always a good idea to test the circuit for leaks, prior to powering up
the computer. Troubleshooting help is available on our we
