Too hot?

I have two 1000 watt hps cooled by a 6" HO (440 cfm) can-fan pulling cold air from my central air unit. My room is still at 82 degrees!!! After I add C02 will that high of a temp greatly affect overall yields and growth rates?

no experience with co2 but all my reading says that 82 is fine, maybe even a little cool, anyone wana give this man a real answer.
