1.) the compressors in a frig/freezer aren't powerful enough to cool a computer, as refrigerators/freezers never have anything is them that actually produces heat.
2.) It's the evaporation of the water (latent heat of vaporization) that causes the cooling in a bong cooler. No evaporation = no cooling.
