Hello there again, I want to talk with guys about positive pressure in cases. I have some questions and maybe someone else will find this topic interesting too So I saw this video: http://www.youtube.com/watch?v=Qe-2ZqmSGug&NR=1 Then went to their page: http://www.silverstonetek.com/tech/wh_positive.php?area=usa Positive pressure is all about keeping the dust out from your PC as you can I see in the video I provided. I think that that is quiet impressing - I liked the part when that guy blew the dust into case and it was blown out right away. Question 1: As we know, heat rises, but if we want to keep our cases free from dust, SilverStone advises to make the top fan an intake fan. I think that this could be perfect in watercooled systems as the heat (AFAIK) is transported somewhere else. Is that so? Question 2: What if I add side panel fans? Also post your ideas or whatever comes in your minds. I hope for an interesting conversation.
