I'd like it to go colder than -50.

Here's the deal ;

I can't use straight LN2.I'm pretty sure if you just poured LN2 on a running motherboard it would immediatly die.Thermal shock is no joke.

By using Isopropanol and dry ice , I can bring the temp down reasonably slowly, thus minimizing the effects of thermal shock.

Secondly , the physical requirements of a tank/recirc system designed to handle LN2 is a lot more mechanically demanding.And expensive.

-----------
I'm really not sure LN2 would be any safer.While using flammable solvents seems really dangerous , in reality , flammable solvents are used every day in industrial applications.As long as the correct protocols are followed , it's really no big deal.
