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...
absolutly worthless. They couldn't even get a 1ghz overclock on that think with liquid nitrogen? Remember those amd thunderbird cpus a few years ago that could overclock 1ghz+ over the stock speed and only using air cooling?
