Alright, so i just bought 4 80mm computer fans of ebay. I plan on using them to bring in cool air/ bring out hot. My question is this, i already have a spot on the top of my stealth case that would fit 2 fans(on my first grow it was just open ventilation). Well Would it be best for 2 intake and to blowing out or 3 blowing out of the case and one coming in? its just i have a perfect spot for just 1 intake right now... so yea if it is hard to understand im kinds peace
The best set-up is Passive Intake, Active exhaust.. This means you use all you fans for exhaust and you create passive intakes (no fan, just holes) The more fans you have for exhaust, the more air you will move through your box. By using fans just in exhaust you create a negative airflow. So any little cracks or anything your box may have, will suck air in, and not let any air or smell out. Hope this helps.
