VR-Zone has a guide up on building a Dual cascade cooling system (2 stages vapor phase change) for cooling the CPU and GPU.
The guide will show you the components that are required for the cascade cooling system such as the compressors, condensers, refrigerants, evaporators, heat exchangers, oil separators etc. and the tools you would need. The cooling performance is definitely great with temperature reaching as low as -111C that allows hot chip like Prescott to reach over 5.1Ghz and ATi Radeon 9800 XT to reach over 660Mhz core.Read more
