Too many assumptions to answer precisely. Chances are you'll feel cooler if the fan is blowing inwards because that will help your body reduce its temperature via evaporation of perspiration. There are much more complex cooling setups that can be achieved that utilise outward-blowing fans though, but a single fan can't will cool _you_ faster if it is blowing onto you.
