...yeah man, you took me wrong, all i was doing was explaining why you weren't getting any help, ...all we have is the typed word so i take pains to be clear.
...anyway, if that is how you have your exhaust set up with both fans sitting on the floor and with all that ducting then that's probably your problem. ...is that white fan a Solar & Pilau? ...that's your intake fan, right?
...i have never used an intake fan because in my early research i recall seeing that both intake and exhaust fans need to be balanced correctly or they work against each other so that may be a contributing factor in your temperature issue.
...and why don't you have the exhaust fan hanging inside the tent connected as directly as possible to your scrubber, the longer ducting run, with bends, greatly reduces the efficiency of the fan, ...it will also significantly reduce the lifespan of the fan i'd imagine.
...here's a few pics of how i have my stuff set up, first the veg tent which has no scrubber attached so it's just a 265CFM squirrel cage blowing straight up and out, ...i have no pictures of the intakes but all i did was put 8inch ducting elbows on either side with a short piece of ducting run to the floor of the tent, ...it doesn't need to be 100% light tight because it's only a veg tent.

...now this is my 4ft x 4ft closet where i built a raised floor to allow for intake air to flow beneath the grow and to enter through the back.

...and this is how i have my exhaust set up and you'll have to imagine it piercing the panda plastic wall as i didn't take any pics of that, ...my door is still gaffed so i wasn't proud enough to take a picture of the finished product, lol, but trust me, it just goes straight through so no ducting really at all (there is about an 8inch piece that connects to the exhaust side of the fan and pierces the panda but not bends, anywhere).

so hopefully that will help you out and in the future i'd recommend you develop a thicker skin or you will end up being hounded by trolls, ...they live for baiting people with thin skins.
peace, bozo
