I didn't keep the top filter on during long uses as yes it does restrict the flow a little bit. If I was gaming or messing with the computer for a long period of time it would not be on.
While running on air my temps did not raise at all with it on though so I would say it did not hurt it at all. With this case, you have about 1" extra on the outside of the fans with just open holes for pleanty of dust and pet hair to get into, so that is why It was placed up on top.
I do not have it on at all anymore as that is where my RAD is located and I do not want to restrict any flow from that.
Now I am looking at seeing wht to add to close all the extra holes around my RAD. We will see.....
