The semi-classical Hawking evaporation process of Reissner–Nordström black holes is analyzed. It is shown that this quantum mechanism may turn a near-extremal black-hole spacetime with 
into an horizonless naked singularity, thus violating the Penrose cosmic censorship conjecture. It is therefore conjectured that, within the framework of a self-consistent quantum theory of gravity, the Bekenstein–Hawking temperature should be bounded from below by the simple relation
