That's not so. The dissolved CO2 calculation depends on the temperature during fermentation or after, and the highest temperature that it reached. The reason is this- no more co2 is produced once fermentation ends, so even if you get the beer super cold it's not going to have more co2 in it than it did when it was warmer.
Don't worry about the temperature- you can bottle it cold and then let it sit at room temperature, using .75 ounces of corn sugar per finished gallon.
