I wonder about that as well. This isn't pokemon where fire beats ice.

Who says that he can't cool down the magma blasts? Unlike Ace's fire, magma has a solid form that could be affected by Aokiji's freezing abilities. While it is true that Akainu vaporized a huge iceberg, it doesn't mean that the result would be the same against a named attack.
