OK so I am building a shush box for my InFocus LP330. As all of you know that the PJ is pretty loud but has a pretty good DLP picture and be had for around $1k used. I have already got the box built but am now trying to get the fan that moves the most air yet is the quietest. Kinda a catch22. Well I found some fans at my local comp store that seem one size bigger than the normal computer fans that go on the back. It moves 87 cfm and is 25 db. Well I powered it up using my computer and that thing was spinning its A$$ off. Sure it moved alot of air but it was very loud. I didnt think 25db would be so loud. I have heard of 20db fans but cant find any at any local stores that carry one. Where would I be able to order it? I am doing one fan pusher at the bottom of the box and one fan puller near the top to extract the hot air that is rising. Probably going to be hooked up to the HTPC once I build that too but I would like to be able to use them with a good old DVD player like I have now. Thinking that this would be the cheapest route

But I think that one of these would be best

For the simple fact that I could actually slow down the fan but it would still move enough air. It moves enough air just by spinning it with my fingers. It doesnt need to move thousands or RPMs. So I guess I am just looking for some help. I have done a search on this and it is a little vague on this subject. This is my first post so I hope it isnt too long. Thanks for any help.
