Need Help With Fans in Darkroom 80

Hello I received my secret jardin darkroom 80 I am wondering how I should set up my fans? Should I buy fans and make one an intake and one an exhaust I want to keep temps down so I will run the intake fan at the bottom ofthe tent and the exhaust at the top. Is this the best way to do this? I do not have an air cooled reflector and am running a 400w hps

I have the same tent.. and I just used a 6inch vortex fan to draw heat out the top of the tent. Im running 400w Superlumens HPS and my temps are 78°
