Initial CPU temperature, as measured in BIOS, was -16°C but after running for a while it settled at -10°C. The power supply was home-made from a 240v-12v toroidal transformer (two 12v outputs each capable of providing 9Amps, only one 12v output used) a 10amp bridge rectifier (KBU10M) and a 68000µF16volt electrolytic capacitor. For this test power for the pump and ancillary fans was provide by a bench PSU, set to 12volts and capable of providing 2Amps, although 1.1Amps was max current required. Cooling had to be supplied for the pump, which heated up noticeable at the base, and the bridge rectifier which still got very hot even with a heat sink and fan. The transformer also got quite warm. Some measured parameters: Initial Peltier starting current 8.4Amps, settled to 7.8Amps when playing a movie on PC. Peltier (PSU) voltage 13.5olts - Steady throughout test. Water temperature : Start 20°C, After 3 hours 27°C
