i watched the youtube video. i would think the first thing to fail would be the power supply fan. its little motor is designed to spin in air, which has virtually zero viscosity, not mineral oil. maybe the mineral oil will keep the motor cool enough when under the heavier load of moving liquid rather than air. having said that, the power supply may stay cool enough due to the convective fllow of the mineral oil induced by the heat generated by the power supply even if the fan motor burns out.
for the same reason, i would think the fan on the processor heat sink will also fail, but again, the flow of mineral oil past the heat sink may carry heat away fast enough. so, the heat from the computer is transferred to the mineral oil. i get that. what cools the mineral oil? perhaps you just depend on conduction of heat through the acrylic of the aquarium. however, i believe acrylic has fairly low thermal conductivity, and unless your setup is in a breezy location in the house i would think over time the mineral oil will warm up. also, if you light the enclosure (as you would light an aquarium) that will add heat to the oil bath. i have an aquarium lit with a couple of fluorescent tubes, and it requires a chiller in the recirculation loop in the summer due to the heat from the fluorescent tubes. good luck! -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
