I have posted a few threads on here trying to resolve my heat issue, and I never seem to figure out a solution that actually works for me. I have came a long way since I started having heat issues and trying to fix it, so hopefully this will be the last thread that I have to create about the subject.

I have an enclosed 4'x4'x6' flowering room located in my basement, which actually does not have any fresh air intake besides the air leaks in the structure and when I open the room. The average temp inside of my flowering room with the lights turned off, is roughly ~74-78F, and with the lights turned on ~84-88F. I have a 315w reflector that is being vented outside of the room back into the basement. Venting my hot hair back into the basement is not the issue, because I have placed thermometers at both locations for air intake and exhaust and the temps are within the average ranges that I have stated below.
Basement Temp: ~72-75F
Room Dimensions: 4'x4'x6'
Lights OFF Temp: ~74-78F
Lights ON / Door CLOSED Temp: ~84-91F
Lights ON / Door OPEN Temp: ~79-81F
Here are the two fans that I am using to push air just through through my 315w reflector:
Extraction: 334 CFM Can Max Fan ( https://www.amazon.com/gp/product/B004C2IWIE )
Intake: Lowes Inline Fan ( https://goo.gl/Vfhdzn )

I decided to see what would happen when I left the door to the flowering room completely opened for passive air intake, which there was not much change in the grand scheme of things, however, where the thermometer is located it went from 86F to ~80F. It would appear that even leaving the door completely open is not enough to effectively cool down the room. I left the thermometer out of the range of the light coverage, because I have been told this could warm up and give false readings. You can see my thermometer in the first picture strapped to the stud with some green garden twist ties, however, I typically leave the thermometer clipped onto the LED panel, which sits way lower than the CMH and the temps get awfully hot and makes me wonder how a plant could even survive under the CMH fixture.

From my understanding here are the possible routes that I could attempt:
#1). Air conditioning. I could get a smaller (portable?) air conditioning unit, which has a thermometer built-in that can maintain the temperature by starting and stopping when needed. I am a bit concerned with this route as it's more expensive, and will need to be running to cool the area down. My thoughts are that since the room does not have air circulation that it will have to run less often to keep the flowering room cooled down
#2). Add actual ventilation for the room air exchange, and simply not the light reflector, which means I would need to purchase two additional fans for proper air exchange. There was ventilation for the actual room air, but I heard that I would have better odds trying to combat my heat issues hooking my light directly to the ventilation without anything in the room.
#3). Give up and give all of my money to dispensaries for the medicine I need.
