A German from Hamburg was so fed up with the noise his PC was making, during a drinking session with friends, he wagered a bet that he could solve the problem.
A year later, his PC is still working perfectly still in 30 litres of salad oil.
He leaves the ventilators on to keep the circulation of the oil going. The harddisk is the only thing not in the aquarium which he used as a case for the PC.
He does warn that the PC and keyboard and muis need to be on different height levels, otherwise the oil has a tendancy to creep through the cables and leak.
The only disadvantage with using the oil as a coolant is that after a while it begins to smell.
