    Posted: 28 Jul 2012 at 7:56am
Have had my rig for a couple of years and now need to change one of the fans on the top of the case (800D).  Never really thought about the flow direction of the case fans.  The top fans blow into the case.  The bottom fan blows into the case.  The rear fan blows out.  Is this the correct airflow?  Config is below.  Thanks.

When DS tested the rig they probably found the top fans blowing fresh, cool outside air over the rad worked best.   The heated air from inside the case might give the rad less cooling potential.   I would leave it with top fans blowing in. 
 
Some cases with better air cooling with larger fans and more of them would probably work either way, but the 800D only has the single 140mm blowing in from the bottom. 
 
There has been some discussion about whether to blow out to give the case better airflow or in to supply the rad with better air.  DS did the testing so I'd stick with it , in my opinion.
 
Hope this helps and good luck.
