I don't see why people don't stick with CO2?

It's so cheap and that stuff it pretty cold too. It's a liquid when it's bottled, get it on something you want cold... BAM! it's cold!

I can give free fills to all of you too...

 

O, hahah someone already stole my idea with that N-tercooler thing. Bastard!

 

I ran a whole evening at BMP with a block of dry ice sitting on top of my TMIC.

I'm not sure what those of you with FMICs would be able to do though.

By the way, any good ductile aluminum should have no problems with the temperatures posed by dry ice.
