Please Help Cooling Grow Room???

Have a 10x10x8 bedroom. I have 3 600w hps air cooled hoods being vented out of window by 600cfm fan. And have 440 cfm fan pulling through carbon filter out of window too. Fresh air being pulled through lights and pushed though holes in the wall from another room. Temp won't drop below 83 with door open and gets to 91 with door closed. What should I do??? Any suggestions would be grateful please!!!!!!
