MSI Wind U100, Overclocked With Liquid Nitrogen

The new Intel Atom frequency World Record ... and some
damn cool pictures!
A large copper pot is used, sitting on top of the GPU and chipset, and cold transfer through the original heatsink plate to the CPU. This was cooled down to about -20 C to achieve the new world mark. (Intel Atom N270 @ 2315mhz) For more information you can check out the original forum thread.
All this shows is that Atom is clock limited by design. A 700MHz speed up - less than 50% in this case - from using liquid nitrogen? And all to get a CPU that's about as powerful as a 1.5GHz Pentium M or a 1.2GHz Core 2 Duo ...
Atom is reasonably neat, but I would have been more impressed with under-volting to half power consumption. Or designing a better chipset.
I've always wondered why things like this don't cause physical problems related to thermal expansion/contraction - why doesn't the processor package crack due to the temp differences? Or condensation form in bad places etc? There's gotta be a whole list of bad side effects to worry about when supercooling one part of your computer...?
I work for the Department of Redundancy Department.
It's generally not a good idea to keep liquid Nitrogen in a closed system - it expands by something like 700 times when it goes from liquid to gas, so either you need to keep it cool - hard to do if it's sitting on a hot-plate, or make the pot extremely pressure proof... And then you still need to keep it cool. Best to just let it boil away and top it up...
