12" Exhaust Fan To Cool Room

Any help would be appreciated. I'm using (2) 1000w water cooled Fresca Sol. I want use 12" 1060 cfm exhaust fan with thermostat to remove any heat. Noise is not a problem.

Would this fan be efficient enough to keep 6x4 tent below 78F without little to any help of AC?

The reason for bigger fan is I might upgrade to larger room later. Keep myself from buying twice.

That 12" fan is more than enough for a 6x4 tent. But as for cooling the tent, it will depend on the ambient air that is being sucked into the tent. If your ambient air is cool, then it will not be a problem.
