HEAT ISSUES/ CLOSET STEALTH GROW

Working with a closet space area about 5 foot wide, 6 ft tall and 3 ft deep. Cold weather was on my side as Ive been running a 4 ft cfl light bar and supplementing during flowering with 2-3 more clamp on cfl lights that produce quite a bit of heat, but now where im at its warm out again.. not even peak heat like it will be so I know I need to take care of this problem early before spring & summer hit..Closets about 75-80 degrees when lights are off.. but runs about 90 with my lights on. I have a top exhaust I made with a blower fan, the kind you would use for outside blow up decorations, definitely different but its really powerful & sucks up heat & duct running to outside.. I figure heat rises so the best place to put it would be up high. But still my temps fluctuate 85-90.. meaning not only is it hot in my grow space but my water temps are running a bit warmer then id like. I have invested in very big ice packs and they worked throughout my last grow but its definitely a pain in the ass. I need a way to get these temps down ASAP.. maybe pumping cool air into the space? Im also running a single box fan & keep it on high.. should I invest in another? Perhaps an oscilating wall fan to keep up higher focused on my light? ADVICE PLEASE

You need a way to exhaust that heat in exchange for colder, fresh air. My little cabinet gets up to 32°c with a 90w COB. But there's only a weak air exchange going on. And that's with the outside temps at 28°c.

Problem Resolved & I appreciate your input Nugachino. What I did was take my exhaust blower & put it at the opposite end of the hose under the house where it stays cool even in the summer. The duct runs straight to my grow room and pumps all the cool air I need! I also have it set on a timer. Kicks on in hour increments & stays on for 30 min at a time. I now have a PERFECT temp control room.. I highly suggest this to Anyone with temp issues.. this is more effective & easily controlled than any of my friends exhaust / temp control systems. Virtually turning a blower motor into a small AC Unit!! Small and can be hidden anywhere cool
