exhaust and intake problem

ok so ive set up my first of my cabinet, now im getting the exhaust all figured out then its ready to go. heres a diagram of my setup so far, bare with me its only using paint. so i have the intake at the bottom of the cabinet, running up a 1.5" pvc tube with a fan at the top sucking the air in. at the top i have two pc fans pushing air into a carbon filter located in a seperate compartment, exhausting to the outside of the cabinet in the back. ive tried so many thing but my issue is way to high of temps. its usually around 105 F and im trying to get it down to 75, 30 degress difference, so any suggestions please hit me up.

Damn dude, i just built my cabinet and i was planning on doin the same exact fucking thing. what size light are you using? hit me up with a private message

well sorry for the no private message but im using 4 42w cfl and 3 24w cfl for the middle of the plants but im not growing anything yet. im actually gonna do some hobby growing with bonsais then once my setup is 100% final then maybe move on haha but yeah for sure this setup is gonna work i think, the best thing to do i think is making intake in each compartment, obviously not the utility compartment but otherwise each have its own intake, i havent tried myself but am going to i think, the only things is making it light proof and sound proof.
