  The cosmic censorship conjecture essentially states that naked singularities
should not form from generic initial conditions. Since black hole parameters
can change their values under Hawking evaporation, one has to ask whether it is
possible to reach extremality by simply waiting for the black hole to
evaporate. If so a slight perturbation would likely render the singularity
naked. Fortunately, at least for the case of asymptotically flat 4-dimensional
Reissner-Nordstr\"om black hole, Hiscock and Weems showed that it can never
reach extremality despite the fact that for a sufficiently massive black hole,
its charge-to-mass ratio can increase during Hawking evaporation. Hence cosmic
censorship is never violated by Hawking emission. However, we know that under
some processes, it is easier to violate cosmic censorship in higher dimensions,
therefore it is crucial to generalize Hiscock and Weems model to dimensions
above four to check cosmic censorship. We found that Hawking evaporation cannot
lead to violation of cosmic censorship even in higher dimensional
Reissner-Nordstr\"om spacetimes. Morerover, it seems to be more difficult to
reach extremality as number of dimension increases.
