– Hot side: a passive aluminum heat sink from a Power Mac G4 466
– I was concerned the heat was slipping through the outside fins. Put a shroud around the hot side of the cooler. This would prevent the loss, and gather the heat. Found an aluminium control box from a washing machine. The shroud also prevented the heat from reaching the Thermalright cooler fins.
– little 1-1/2″ x 1-1/2″ square piece of copper. It was used as a spacer/transfer sat of heat to the peltier module. Use a copper pipe, cut length wise, pound flat and buffed up on the grinder.
– Peltier module (Claims it’s 90 watts, ebay@$10.00)
– Model TEG1-12710 Note: Click here for a good web site about Peltier markings
– 40mm x 40mm x 3.3mm
– Power input from 0-16 volts DC and 0-10.5 amps (when used as a thermoelectric cooler)
– Operates at temperatures as high as +350 deg F
– Each device is fully inspected and tested
– Fitted with 6-inch insulated leads
– Perimeter sealed for moisture protection
– Zalman’s cooler paste. **A must have. This grey goop was cheap and was included with most CPU heatsink kits. It really increased the heat transfer and the voltage.
– Thermalright CPU Cooler. Rated for a 120mm fan. Aluminum base
– 1.5 to 3.0 Volt DC Hobby Motor **A must have. The earlier motor, needed a couple of volts to get running. But, hobby motor required 1.5 volts to start. So, I broke the “made-from-junk” rule and bought a small hobby motor for The Source (Radio Shack) @ $4.99
*Note: a standard 4″ computer fan didn’t work. Not sure how other people can get theirs going?
