Reading the limited number of words in English and guessing the rest:

The cooler is a tower made, it appears, out of copper (or an alloy with a high quantity of copper). It's hollow in the center and it's evidently filled with liquid nitrogen - which should cool the package of the processor to a point very close to -196C or -320F. (since the boiling point of LN is there and it should hold very close to that temperature until the LN has boiled off).

This is a pretty risky way to cool a CPU. Aside from the obvious dangers of working with a substance that's -320F, there's also risks to the CPU package (thermal expansion creating metal wear on the pins and bump pads) and the motherboard.

I wonder if the memory, the memory bus, or the speed of the control signals from the chipset isn't limiting the processor from running faster. I would have expected it to go substantially faster than 1.7GHz at approx. -196C.
