Thanks for the help Dub. I think I am just going to have to roll with what I have. I literally have NO space left inside the cab. Here is a run down of my air flow. I'll try to post a pic of it next time i update.
Bottom left corner I have 80mm PC fans (not sure the CFM) blowing air into the cab. Upper right hand corner I have a 4" inline fan rated at 80CFM. I attached the carbon filter to the outside of the 4" inline fan. This is when my temps shot up....but I kinda expected it. Inside the cab, I also have a 6" fan blowing air around....especially across my CFLs. My cabinet is in an extra bedroom that I only use as a workout room. Lately, as the plants starting to get bigger with bigger buds, my temps have been increasing, so I have been keeping the door cracked until lights go off....even if lights go off with the door cracked, it is completely dark in the extra bedroom...so having the door cracked is not an issue....it only affect the SMELL!!! And what a sweet smell it is. But, I do have an inspection on my apt on Monday. I am not sure if they have to look in every bedroom or what kind of inspection it is....I'm waiting to find that out from my apt manager today.
