high temp problem ( homebox XL,cooltube and 5 '' 350m3 extractor )

i have major temp problem ( 27C in homebox for now,it will be hotter in summer ) .
i have 5 '' extractor (350m3 ) @ 5"cooltube with 600w dual spectrum hps.i also have a 400m3 carb filter.i have homebox XL .

homebox XL growtent is 1,2 metre X 1,2 metre X 2 metre. it is in a room where 5 metre X 6 metre ( yes it is a big room )

exhaust fan extracts air from tent to outside of room (in fact,outside of house from roof ) where homebox in it .

we are in spring and it is almost 22 C here. in summer,it will be getting hotter ( more than 25 )

the temperature in the grow tent is always 5 - 6 C hotter than room. what can i do to decrease temperature in homebox ?

if i upgrade my extractor,i will have to change my carb filter ,too. ( that shits are expensive ) .so i want to solve my problem without buying new carbon filter .
my current Air flow:
carbon filter> cooltube>extractor>outside of the tent

i can add a 5 '' extractor for cooltube (new airflow would be like this : air flow1 : outside of tent > cooltube > extractor>outside of tent,airflow2 : carbon filter> extractor > outside of tent )

homebox doesnt have extra vent holes for cooltube.i also have to buy homebox flange and homebox reducer ( total cost of homebox flanges to penetrate 2 holes for cooltube is 60 € )

if i had darkroom secret jardin,i would choose this :
( air flow1 : outside of tent > cooltube > extractor>outside of tent,airflow2 : carbon filter> extractor > outside of tent )

or i can simply add 5'' extractor for active intake .

Adddind a 5'' rvk extractor for active intake is simplier ( and cheaper ) for me . cant i decrease temperature by adding a 5'' rvk extractor as active intake ?

What is the benefit of active intake extractor ?

PS : if i add extractor for active intake,the air would come from the room where homebox in .i cant bring air from outside of room where homebox in via active intake .


which is better ?
