In my case i get cool air for the intake and the hot air goes out the side of the case. This means that they will run a bit hotter than a psu that is mounted on the bottom which draws air from outside the case. Deciding on whether to mount your psu either facing up or down depends entirely on a few factors namely case design airflow with other fans and the power supply unit itself. When intel designed the atx form factor the power supply fan was designated as the primary case fan.

Extra cables are easier to manage as they lay on the bottom. My computer sits on my desk and imo i would never set a computer on carpet. Determine where the psu is intended to fit.
