With a thinner base and greater internal volume the CPU-LN2 is the clear winner here for dry ice cooling. With the tall acetal extension the CPU-LN2 is quite easy to bench with dry ice, simply keep it at least half-way full and the temps are quite stable. Towards the end I was getting lazy and tossing large chunks into the tube and I noticed only a marginal difference in performance versus powder and pellets. The performance on Core i7 was quite impressive, I personally thought the CPU-LN2 would cave when faced with a greater load.

FOR LN2 though.... How best to put this.. the CPU-LN2 is not an adequate liquid nitrogen pot. I started my testing on AMD's Phenom II X4 955 and even with the pot full of nitrogen I was still seeing massive(20C+) swings in base temperature through the relatively short 3D06. For example I can run 3DMark 2006 at 5900MHz on my F1EE but I had to drop down to 5650MHz with the CPU-LN2 due to the processor getting too warm through the CPU test and crashing. wPrime 1024M crashed at 5800MHz typically between 65 and 80 seconds.
