  We study quantum gravity effects for Myers-Perry black holes assuming that
the leading contributions arise from the renormalization group evolution of
Newton's coupling. Provided that gravity weakens following the asymptotic
safety conjecture, we find that quantum effects lift a degeneracy of
higher-dimensional black holes, and dominate over kinematical ones induced by
rotation, particularly for small black hole mass, large angular momentum, and
higher space-time dimensionality. Quantum-corrected space-times display inner
and outer horizons, and show the existence of a black hole of smallest mass in
any dimension. Ultra-spinning solutions no longer persist. Thermodynamic
properties including temperature, specific heat, the Komar integrals, and
aspects of black hole mechanics are studied as well. Observing a softening of
the ring singularity, we also discuss the validity of classical energy
conditions.
