If you like this, Please subscribe to my channel, many thanks. I'm thinking of total liquid submersion cooling..sometime in the future. Answers to some questions: 1) Yes I did use too much heatsink compound initially, but what isn't shown in the video is me scrapping off all the excess. 2) The Peltier (TEC) is a TEC1-12710 from Ebay rated at 154Watts, Vmax 15.4Volts Imax 10Amps. 3) I did not completely overcome the condensation problem - this was just an experiment. What's not shown on the video is that I filled the gap around the CPU/Cooling Block with lots of Dow Corning DC4 silicone compound, this stopped condensation on the top but the underside of the MoBo (where the CPU is) got wet. 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.
