Technology Demonstration of http://www.LN2Cooling.com LN2 cooling evaporator with LHe conversion kit. Conversion kit combined with LN2 evaporator extended run time on LHe4 by a factor of 2. Hoping to try again with a chip that likes voltage, or a new stepping chip! (CPU-Z validation not done with floating HT glitch - easily over 7.1Ghz with glitch)
