You're meant to be running these in server rack cases that already have fans in the front. Most server CPU heatsink designs take this sort of form as well[1], as there's no point in putting a tiny fan on top of the heatsink when you've got delta fans at the front blasting air through what amounts to a sealed pipe. I've dealt with GPUs of a lower TDP in a cramped environment and the amount of airflow you need is completely insane, if you ran this without aggressive cooling for more than a couple of seconds it would just ignite.
