you have 96 sq feet so yes it will work, you will need a passave air intake at least 2sq inches and a little bigger is better, it should be as close to the floor as can be. Without the hole it will be under a fair bit of negative pressure so you need to have ample air avalible for your plants. helps keep new co2 coming into the tent. a good thing.

peace

The air that you will be removing from the tent using your fan has to be replaced with fresh air. The only way to do this is to have a open hole, preferably as low to the ground as possible for cooler air. Air removed always requires makeup air.

Crazy, did you notice that this unit is 12V Dc? You can get it work but, it's not going to be plug an play.

couldnt you just wire it with a 12v cell phone charger like the computer fan idea?

You can wire it to a 12v charger just have to make sure two things, That they are both either AC or DC and that the charger is putting out more amperage than the fan is going to use.

so if i have a phone charger tat reads..input 120ac output 12vdc 700Ma... it still dont have enough balls....cause fan describtion it says "Ignition Protected 12v Dc, 4.5 Amps." so 4.5amps =4500Ma is tat bout correct....i found this adapter its 12vdc 5000Ma..will it work?

Yes, you would have to leave an opening of 2 or more square inches to allow enough air to replace the air removed. If you tape the flap open you should be ok.
