I recently built a new system. My first time and so far things are grand. I got a question on fans that kinda got me thinking for quite a while. When I was screwing on the fans to the side and back of the case, I was woundering which way the air is going? Is it blowing air in or out? Is it even curculating? The front of my case tells the temp. of inside. It reads 82.0 F. I was thinking my fans are probably in right. But I would like to make sure. How would I go about seeing which way the air is going, and how should circulation go? Thank you.
