Over Heating grow room

what are the best ways to cool down a room thats over heating during the day?

im figuring fans is their any other ways ?

Try a different light cycle.(lights on when its cooler) Fans sucking air out of the room.raise the lights.

Your lights should be on at night. Try lights on at 5pm and off at 9am. That's 18/6 for vegging. For flowering, lights on at 9pm and off at 9am. That's 12/12 for the bloom cycle.

You mentioned fans. You should have already had a fan blowing gently in there anyway.
