GPUs can survive much higher temps than humans. Its basically no differerent than a car. A car just uses the outside air to cool the engine and its sufficent. And with a GPU its no different.
Just have a good intake and exhaust setup with a low/high pressure setup and the air should get quickly sucked out of the room. Depending on how many GPUs are in that room, you probably shouldn't sleep there due to the heat and noise however.
Didn't you read the thread? , no miners use air conditioning to cool their rigs. Depending on how many GPUs you got in your place, one air conditioner might not be able to keep up with all the heat.
Also you need to consider that if its hot outside then the air conditioners will be even less efficient because you need it to cool the room from outside heat and also from the heat generated by GPUs. It won't work.
You need to get a good ventilation setup and use a fan for fresh intake from outside and use another fan as the exhaust and stick it near a window so it sucks the heat outside from the room.
It will be very noisy and hot and you probably shouldn't sleep in the same room.
