For example, cooling hens eggs by taking them out of the incubator into a room at 20°C/68°F for 30-40 minutes is likely to cool the internal egg temperature by only 3 - 5°C (7 - 10°F). Also the temperature you incubate your lizard eggs at can determine the sex of the babies if kept within an acceptable range.
