Originally posted on TechPowerUp in March 2009, this oil-cooled PC was inspired by a similar rig designed by Pugent. According to system builder chooky, the cooling system went through several variations before reaching its current state.
"The cooling system has been an evolution from pumping oil through an air-cooled radiator, to evaporative cooling with a bong, to Peltier cooling [next to the PSU]," chooky said. Eventually he settled on a system using a 20 000 liter above-ground pool pumping water to a heat exchanger and a homemade CPU heat block. To see this pool-cooled PC, head here.
