Questions on case cooling, buying tonight

post #1 of 3
Thread Starter 
Okay I'm going to buy some case fans tonight, along with a slew of other parts. I can fit a 120mm fan on the back of my PC, where a 80mm currently resides. I am also buying 2 80 mm for the front, which doesn't look like it will fit a 120mm, doesn't have the holes at least. Also, I have one 80mm exhaust fan at the top of the case. Also, I have a CPU duct with a dust guard, along with a vent below it. I'm trying to keep positive pressure so I keep the dust out. So, the fans I'm getting (someone suggest better if needed) have the following flow rates:
80mm=32.65 @ 2700 RPM, I currently have two of these
120mm=63.85 CFM
I I am thinking about ordering one 120mm for the rear exhaust, then moving the 80mm to the front, and ordering an additional 80mm for the front. This would set my fans to:
Intake flow rate=2*32.65=65.3 CFM
Exhaust flow rate=32.65+63.85=96.5 this is WAY negative pressure, so......what do you guys think? If you know of a better fan that has a higher CFM for the 80mms, let me know, I don't care about noise.
Could I buy a PCI slot fan and somehow set it to intake to balance the pressure? (doubt it, but worth a shot)

WOA I now see these!

Take a look at these:

120mm: http://www.newegg.com/Product/Produc...82E16811999344

80mm: http://www.newegg.com/Product/Produc...82E16811999348

They have served me well, and relatively quietly.

LOL those are the 80 mms that I ordered! I decided to just keep the 80mm apevias in the top and rear exhaust, and put these in the front:

This should keep positive pressure for sure, or I'm a sexy woman.
