Peltier would need huge radiators and fans to dissipate the enormous amount of heat they put out.
The head of marketing at OCZ uses convective water cooling without a pump.
Mineral oil needs to be actively cooled or else it will quickly become inundated with heat and won't be able to keep anything cool.
