I need to cool my grow tent that is in my basment with no windows.
I am running a 600W with air intake and outake running 2 fans inside the tent, for some reason i cannot get my air to cool down to about 76 it stays around 80-81 sometimes reaching 82 i need something where i can use that wont emit more water in the air but that blows out cold air i can use. any suggestions

One 6" inline fan should be enough air movement to cool the tent, unless the ambient temp in your basement is too high. A 4" or even two, probably isn't enough. Is the exhaust at the top of the tent and the intake near the floor? What is the ambient temp in your basement? Unless you install A/C or ventilate to the outside, you'll have high humidity. A mini-split system or chiller would fix it, at high cost.

your carbon filter is probably restricting your airflow. can you give us more info on the fans you are using, what size are they and what cfm?

i have a tower fan and a 6in fan oh and i forgot another 2ft tower fan. the carbon filter is prob slowing it down but not enough to keep the room at that temp. what happens when i am blooming and need that carbon filter?

Those tower fans, if they're what I think they are, are doing nothing to cool your tent, just circulating air inside the tent. Is the 6" fan an inline fan? Does it pull air from inside the tent and blow it outside the tent? if you don't use the filter, your whole house will reek of pot. What is the ambient temp in your basement? Your tent will always be a few degrees higher than ambient.

problem being is the room you are growing in is completely sealed. cut a hole in a door and add a 6 inch fan to extract the heat. it will make ambient temps much nicer for you and your plants.

the temp in basement stays around 70 but will get cooler when it gets nicer out, i have a few ideas like cutting a small hole at the top of the tent and putting a net on top of it to let air escape and keep insects out

but that will negate your filter(having and unfiltered exhaust). is your fan an inline fan? how many cfm? I suggest you look at what others are doing, and mimic that. what you want is a filtered passive intake towards the bottom and a filtered inline exhaust fan towards the top.

A passive exhaust at the bottom of the tent opposite an active exhaust at the top. Run your filter > hood > exhaust fan > out.

A single oscillating fan is fine to promote air circulation.

You make it sound like you have no ventilation at all. Your tent, unless its some piece of shit, should already have several holes for venting. What is your 6" fan doing if not exhausting the hot air? Your responses to questions are vague and contradictory. Perhaps you should just look at how other people have done it. Several people have tried to help you, but you don't seem to have clue as to what they are saying.
