closet grow problems

i have kind of a big problem trying to controll my heat issues and figured i should ask some pros for some help. i have a 2x2x6ft closet set-up with a 400w mh lamp, reflective wraping paper, a box fan that just barely fits wall to wall, and a floor blower fan blowing air out through a hole cut into my wall on the bottom letting air out into another room. i cannot get my temps below 80-81 degrees. i was just wondering if my room is to small for the light or is there aything else i can do to fix my problem. any help would be greatly appreciated. thanks.

p.s. forgot to mention this is my first grow i have 3 that broke soil and dont want to see my babies die this soon.

Should be ok on the light post pics if possible but if ur venting ur light in the room that ur intake is coming from ull need an ac. I would reccomend air cooling it and having ur hot air go into an attic crawlspace or out the windo also ull want ur exhaust top be on the top or at least on a higher part of the cab as heat rises and maybe punch another hole in the bottom. Of the cab and just have a fan exhausting making a passive intake pulling fresh air from the bottom corner across the canopy and out the room.

i also forgot to mention that i have a diy air scrubber going to the ceiling also. that should work for the exhaust on top right? here are some pics. they are not the best but hope they help.

Take that fan and use it to vent the light or exhaust the cab and get a oscilating fan of a couple clip on fans. So the air is being moved around the cab and through the plants. Also with ur venting for the carbon scrubber. The straighter the better the airflow so the anfle it looks like its hangin is cutting its efficieny quite a bit imo. Also is ur light open or is it in a reflector or cooltube or somethin if its open try to get a fan down by the intake aimg up at the bulb and toward the exhaust to help keep the heat high above the canopy.

thanks. ill try to straighten the vent tube out. i took off my reflector cuz i thought it would help circulate the air better without it but it didnt really help. and that blower fan is exhausting air into the hole i cut throught the wall into another room or should i use that hole as a passive intake and exhaust elswhere. i have a fan in the to move the air but couldn't fit into pic very tight space.
