The problem is more about spreading the heat to a larger enough surface area. Heat pipes are ideal for this until the point where the power/area limit of their evaporator is reached but that is what heat spreaders are for and there is always water cooling. If it were not for that, those big air coolers from Cooler Master could handle it easily.
On a less practicable level, the head from a VW Beatle engine handles more than that.
