Stanley Blower for Cool Tube?

Hmm... Think the stanley alone being hooked up like this would do it?

carbon filter tube > duct > cool tube > duct > intake on stanley. Would that cool a 2' x 4' x 6' flower box with a 400W HPS?

I just didn't want to waste these 4 PC Fans I just bought. I think I will take your advice and use those for circulation inside the box instead of an oscillating fan.

As long as the room can get good fresh air, yes.

thanks guys was also wondering about this stanley' but would it work in a grow room self made tent?
connected to hps, ducting to window?
