hmm?
it'll evaporate. speed depending on storage.

read up some ln2 overclocking articles :)

only useful for short term quick recordbreaking.
 
Not hours, minutes. It evaporates very fast but keeps things very cold as it does. The temp is somewheres around -192C.
 
It doesn't last long, is stupiddly cold to the point where stupid ammounts of insulation is needed, and is stupidly expensive.

Its really only useful if you have a sick TOP of the line system and want a top score in Prime95 or 3DMark.

Dry Ice is cheaper and almost as good (like a 100C delta but meh) and is good enough.
 
In the physics lab we were using it in about 2 or 3 L containers, made with 1 1/2 inch thick styrofoam and it only lasted about one and a half hours without any particularly great heatload. 100W of CPU would probably boil that off in 15 mins or less.
