Actually, air-cooling is marginal with these CPUs, even at stock frequencies. There is no air-cooler which allows them to sustain their frequencies under load.
Water-cooling is pretty much required, and an AIO does not cut it. Still, even with water-cooling you can't really overclock these. They are pretty much at their limit out of the factory.
This could conceivably solved by Intel switching away from silicon TIM to e.g. solder, since the Rth(jc) of the CPUs is much worse at ~0.3 K/W than the thermal resistance of a big CPU air cooler (~0.1 K/W).
The overclocking problems wouldn't be fixed though; there is no easy fix for a CPU that jumps to 400+ watts.

An entirely separate issue is that you need to get the heat out of your office. A human dissipates around 50-100 W; you can imagine that a small office crowded with half a dozen people is not pleasant in the summer.
