Grow Room Warm air/cool water

Hey guys, I'm currently growing in a 3 foot tall locker. I have installed 4 80mm 120vac PC type fans. 2 in series each with their own carbon filter, each set moves about 120cfm. I
Am using a passive intake via 3" square hole at base. There is 1 circulation fan that also distributes C02. My room temp stays at a solid 73-74F. My air temp in the box swings from 83-88F during lights on (180w LED). The majority of the heat is coming
From the water chiller. The water temps stays between 66-68F. Realistically I have done all I can do to lower the temp. Turning the AC down is NOT happening and adding some sort of dedicated AC for the box will take away from the stealth factor. My question is, since my water is staying well within range the plants shouldn't stress too much? I am not looking to produce cannabis cup winners, but good personal bud. Am I stressing for nothing?

Just grow. See what happens. And adjust one thing at time. I my self is only concerned about low rh. The rest Is as is.nothing to worry about. Maybe a small inline fan as exhaust will do you fine cost. pennyes.keep it up

Small cabinets are a nightmare to cool - I ended up with a larger cabinet (2 plants) but found that sometimes the circulation fan was preventing the other fans i was using (3x120mm PC Fans) from getting the heat toward my out-take filter. Do try lots of fan positions and try turning their speeds up/down and on/off if they are variable speed - I have one directing heat downward from LEDs towards my filter extraction - at high speed it actually makes the cabinet hotter - one thing I found is you can't see what's going on with the cabinet door closed. I ended up using my mobile to record a video for a min with the door closed to see what was going on. My main circulation fan got dumped because it was creating a tornado as opposed to a gentle breeze. It's a dark art and changes as the plant(s) fill your space. My main problem is ambient room temp which on a sunny day can go up by 3-4 deg C - which is enough to tip me from a happy 27C towads 30C. As your already using aircon in the room there's not much I can suggest tbh except experiment with positions and speeds before you try to add more,
