Temps too HIGH!!!????!!!!

I have a 4 x 2 cabinet with 5 feet of height my temps are running 82 with doors closed and 77 open I have 240 cfm of exhaust and 185 of intake... any ideas???

82 is just fine.

A lower temp might be better though. get a gallon jug(or smaller if wanter) of water and freeze it. After it is frozen leave it in the cabinet (make sure it does not drip on electrical wires or anything) and see if the temp goes down. I know its ghetto but hey ghetto does not mean unreliable.
You can have one jug in the freezer while one is in the grow room.

You are fine. No action necessary at those temps.
