5 Stage Phase Change Cooling Cascade Being Build

@ 2009/04/15
We've seen single stage phase chase cooling units go retail, dual stage units build by many enthusiasts, even triple stage units in action at large overclocking events... this one takes the cake though, five stages, whatever temperature he's aiming to achieve, it will be well below zero.


Will this monster, once finished, be able to tame an overclocked Core i7 ? What do you think?

I think it would be better off not using Argon or N2 as it will quickly get converted to solid state as the difference between the boiling point and Melting point is 3.5 Degree Centigrade(Argon) and 15.2 Degree Centigrade(Nitrogen)...

But Helium-4 can be used as its Melting Point is, -272.2 Degree Centigrade at 25 times the Atmospheric Pressure, which is extremely difficult to achieve.
And Boiling Point is -269 Degree Centigrade at sea level. So in these units where Pressure can be increased a little bit it may be the ideal choice...
