Can you give us more information? So the temperature is too high? What are you using for lighting? What are you currently using for cooling? A 6" inline fan may be better.

75-85 degrees is a better lights-on range when growing with LED grow lights. If it drops to 68-75 when the lights are off then that's fine. The humidity range you mention is also fine.
