Another variant of this cooling system is to use oil instead of water. Since the common oil does not conduct electricity, some customers have successfully tested the technique on the motherboard completely immersed in a container previously filled with mineral oil, and then make the circle by a radiator Watercooling normal.
This system is able to isolate the motherboard from potentially harmful external elements such as dust or moisture. The obvious disadvantages are the result of maintaining the computer or its components are submerged in a container filled with liquid. This has been represented as degradation of the capacitors in the circuits by the gradual penetration of the liquid themselves.
In tests where long remained submerged in a socket 478 motherboard with a Pentium 4 3.2 GHz for a month and was then extracted from the liquid and mounted on a common chassis, the team kept running smoothly for over a year .
It is recalled that the cooling system is used for decades in transformers and other electrical devices. Regarding computer use is mostly experimental and traditional, often promoted by the computer enthusiasts who explore new alternatives. However, the Apple PowerMac G5 computer is an example of a commercial implementation of this cooling system.
A simple application form from the cooling oil is the replacement of water by oil in Watercooling a traditional system, adding a larger capacity radiator. You can also implement a cooling system of this type occupy a cabinet full of tight dielectric fluid (oil or liquid that does not conduct electricity, especially designed for these purposes) in which all elements are submerged with the exception of computer disks hard. This allows direct contact between the liquid and the hot components like the processor, GPU, etc.., To dissipate the heat and then this, in contact with the walls of the cabinet and thus to the outside air, transfers finally heat to the environment. This method is sometimes called “passive” because it does not require any kind of pump or fan, but can be improved with some mechanism to remove the liquid within the cabinet and favors a more homogeneous distribution of temperature.
A more complex way is to submerge the motherboard in an aquarium or container filled with mineral oil, and then install a Watercooling system to circulate the oil for a radiator for heat dissipation that is exchanged with components submerged.
