24000BTU air conditioner.
4200W power for 48 GPU+ mobo.
The room seems cool. No any heat problem so far. I feel cold air in the room.

But i fear if any type of hardware failure hot air and cold air in the same room.
I dont want to use ventilation system. I want to use AC.
Should i send the cold air directly to the rigs ?
i use wall mounted split AC.
