hi dude, do you have the means to install an extractor fan? if your room has an AC, then with the extractor fan to which you also can attach a carbon filter to control smell, you will start extracting cool air through the lateral small vents into the tent and it should do the job. At least 2 fans (one over the canopy and one below) and if they oscillate would be even better.
How much are your temps?
Try moving your light schedule during the night, this also helps.
