Excellent question. A rule of thumb I use is 1 hour or more use the fridge. A half hour in the freezer will take the edge of a warm beer or cool a room temperature beer to decent temp. One hour in the freezer is about as far as I go unless I forget to take it out. Beer bottle cooling Stages: Hot: left in car.
Depending on the type and size of your freezer, it generally takes anywhere from 12-24 hours for your freezer to become cold enough to keep food frozen. A good way to test this is to put an ice cube tray with fresh water into the freezer - when the ice cubes are frozen, it is cold enough to freeze your food properly. Of course, you also want to ensure you leave the freezer door shut as much as possible, so cold air doesn't escape. So resist the temptation to check it every hour from the moment you plug it in. Wait at least 6 hours before you take your first peek, but a good time frame to expect is 12-24 hours. If you have food you need to keep frozen in the meantime, a good ice chest or cooler with some blocks of ice will usually be sufficient to kee everything cold - just don't leave it in the sun or any other warm spot.
