III. Thermoelectric connections
• Wiring extension & connectors: due to the high current requirements of the thermoelectric module, standard Molex type 4
pin power connectors are prohibited.
• You are likely to need extension wiring to connect the module to your power supply. Use 12 or 14 GA. stranded wire
only. Connect the extension to the existing wires with terminal splices, or solder the butts, and insulate with shrink
tubing.
• Power supply requirements: the thermoelectric module is optimized to run at 12 VDC, but can be run up to 15 volts DC.
There is no advantage to run the module at the highest voltage, as performance decreases. Current requirement is 20~24
amps. A good quality dedicated switching power supply is necessary.
IV. Temperature troubleshooting
IMPORTANT NOTICE: AMD compatible motherboards measure the CPU temperature via a thermal probe located inside the socket. The
probe only measures the air temperature underneath the CPU. Motherboard manufacturers use mathematic formulas to extrapolate the actual
CPU temperature. Such formulas use correction factors to account for airflow around the socket generated by a conventional heatsink fan
cooler. In a liquid cooling environment, there is no airflow at all around the socket, since there is no fan attached to the water-block. This
leads to erroneous readings from the motherboard thermal probe, which reports much higher CPU temperatures than actual. Our tests
evidence up to 20
° C difference between the temperature measured under the socket, and the temperature measured at the cold plate.
