I don't have time now to RTA but if one was to use say a non conductive, non corrosive refrigerant one could make use of the lower vapor point to more efficantly remove the heat AND even better lower the operating temperature considerably. A split cascaded system would be my choice as you could achieve very low temps with the possibility of modularizing the components so the point of use (the chips) is a relatively small inexpensive unit that is supported by layers of larger systems. Visualize the module as cube with a pair of hoses that connect to larger refrigeration systems, just another connector service like power, data or control. Within the range of the temps allowed by the refrigerant one could very easily throttle the temps depending on need.
Hey we run hundreds of hp high voltage motors immersed in refrigerant every day in industrial settings.
Cascaded freezer systems are common in labs and liquefied gases production uses similar systems on a massive scale.
Just using the benefits of the more efficient heat transfer from immersion and lower vapor point should make for reduced operating costs. Initial costs for todays common hardware is chump change compared the energy costs so there is hope if something can be produced cheap enough.
I personally like the idea of the extremely low operating temps that could be used to enhance performance.
