Modding the great Chieftec Dragon

Ok so I am gonna start working on my dragon once again and plan to put 2x120mm in the front and 2x92mm in the back. However, I was wondering if the pressure in the case is going to end up being negative due to the fact that I have dual 120s in front and only dual 92s in back. The psu I have does have a single 120 in it so will that make up for the difference in air flow?

Thanks for help.
 
I don't think you'll have a problem. You going to be using filters for the fans at all?
 
On the front I will probably rig something up for a small mesh filter, like laundry sheets or something. I have completely cut the front out and will be putting modders mesh in its place with 2 blue 120s behind it, so more than likely I will try and rig up some sort of filter system that I can easily change. Hopefully, soon you guys will see the work log here.
 
I doubt you'll notice much pressure difference. If you want to be sure, I'm sure you could check the cfm for the various size fans, and match them pretty closely, though that would make your 92mm fans a bit noisier than the 120mm fans. For instance, I checked a couple over at Xoxide, and the 92mm fan with ~55cfm runs at ~35dBa, while the 120mm fan at the same cfm runs at ~16dBa.

Oh yeah, don't forget to take the power supply fan(s) into effect too! :)
 
Well the reason I am not doing the 120s in back is because there is not enough room to fit 2 like I would like. I was thinking that I could always just go with quad 92s all around. And yes if you look at the original post you will see that I was taking into effect the 120 for the psu as well.

Edit: sorry if that came across rude but it was not meant that way. Anyone got any recommendations for some quiet, blue led fans?
