Tent height and cfm's using same wattage

Hi, i have an original gorilla tent 2x4 that is 6' 11" . I made a test run with 300w LED using AC infinity T6 and found that to reach maximum temperature of 80F (my max for flowering because of terpenes) i have to run it on level 5/6 (200/240 cfm) which unfortunately is too loud in my bedroom that i share walls with neighbors. Gorilla support and their site say that bigger height bring temperatures down because of hot air rising but im confused since the air is replaced so fast that would it really matter ? Because of that im thinking about buying their smaller version which is 4'11" / 5'8" which is about 70%/80% of my current space of air. Using the same light would running my fan on the same setting would bring temperatures down or the heat would build up more and i wont have option to use lesser cfm's ?

Put inline fan outside of tent. If you can put drivers outside also. Don't intake and vent in the same room. Open ports. Search function.....

That is not what i was asking for - it was the heat regarding to height. My exhaust is blowing through cracked door to rest of the house, my drivers are outside - you made million assumption knowing very little.

I found out that high pitched noise is created when i attach my carbon filter. Is it normal that resistance of carbon filter makes fans create it when they have to work harder ?
