We find a new black hole solution in Randall-Sundrum II braneworld scenario in the presence of an anisotropic perfect fluid in the brane inspired by the noncommutative geometry, thought to be an effective description of a quantum-gravitational spacetime. We find that the curvature singularity at the origin is smeared out by the noncommutative fluctuations and study the horizon structure to show that the geometry admits two, one or no horizon depending on the value of the mass parameter M with respect to two threshold masses which depend on the noncommutative geometry induced minimal length. On the thermodynamics side, we show that the black hole temperature, instead of a divergent behaviour at small scales, admits both a minimum and a maximum value, before cooling down towards a zero temperature remnant.
