They are designed to be operated at much higher temperatures because the use gas as a coolant where they can effectively use natural convection to remove decay heat.

Yes and no. Not all gas-cooled reactors can work completely through convection cooling without melting, some do need fans even to just remove decay heat.

Also, reactors containing graphite (as many pebble-bed reactors will) do need a oxygen-free atmosphere, otherwise the graphite will ignite. So only convection of the proper uncontaminated protective atmosphere will work.
