Unable to keep the temperature from rising 10 to 15+ degrees celcius

As an example tonight with the newly put in 200mm active outake fan and adjusted for you crazy fahrenheiters

8:00pm 66f/19c
8:20pm 80.24f/27c
8:40pm 85f/29c

Specs

Grow box (forget dimensions)
600w hps - glass cover and sunon mounted fan
Ventilation tube ranges from 150mm to 200mm
New 200mm inline fan

Box



Sunon fan the same as the one attached to the hood



600w



Venting around sunon mounted fan only cable tied, not sealed perfectly



Passive intake bottom right corner of the box



A foot or so of venting from the hood to the outside of the box, sealed tight



Outside view of the active exhaust before mounting the 200mm venting and 200mm inline fan on



Newly Mounted 200mm on the outside to try and stop this rising temp problem, didnt work.



Thoughts? Remove the sunon from the hood and air seal the ventilation to it and see how the 200mm goes then? buy a second 200mm?
