An uncommon practice is to submerge the computer's components in a thermally, but not electrically, conductive liquid. Although rarely used for the cooling of personal computers, liquid submersion is a routine method of cooling large power distribution components such as transformers.
To Determine Sub-Cooling: 1  Take the high side pressure and convert it to temperature using chart or gauge. 2  Then take the temperature of the liquid line as close to evaporator as possible before the metering device. 3  Take the difference between the above readings.  Sub-Cooling should be around 12-15 degrees.
