temp problem

hey fellow growers need some help with my flower room tryin to get the temp down it is 6ft x 6ft x 6ft i have 2 600watt hps standard reflectors cant get the temp below 36c i am only using a 4" extractor and my intake air is 20c would another 4"extractor make a difference or get one bigger one
Need to get it sorted quick my clones are nearly ready to go into the flower room

cool tube your lights or get bigger/more fans going.

what about putting a 6in extractor and a 4in on the intake to boost it would that help and i also have an areowing but no glass in it

does anyone know another option other then cool tubes
