yes it would work on a freezer. Since it's only like 6min. I don't have to worry about condisation. I will overvolt and do it tonight when I get home from school. But I can only do stock gpu runs with how hot it is in this school.
Actually if you have a fridge with a bottom freezer that pulls out with shelves in it would work (being serious). Over the summer I used my central air in my house for additional cooling. Put my Cryo cooler right on top of a vent and it was pushing the cold air very nicely. My system got nice and frosty.
