Try 2 Sunon 120s...I have 2 on the intake (and 4 80s through the drive bays and 2-92s moving things around and out) and my computer fairly howls. I have heard good things about the Panaflos baing quiet, but I think thay are a little hard to find.
I'm lookin at the Panaflo FBA12G12L1A 68.9 cfm at 30 Db, the FBA12G12M1A 86.5 CFM AT 35.5 dB and also the Delta WFB1212LE 84.7 cfm at 34.5 Db, WFB1212ME 96.4 cfm at 38 Db. Sunon also has a KD1212PMB3-6A 84 cfm at 35 Db.
I just got 2 of the panaflow 120's from 2cooltek and they are a lot quiter than any std 80 fan I have seen.
Oh yea he has the quiet 80's too. I am going to quieten this damn case of mine one way or the other.
One thing these are some big THICH fans. must be 2 inches wide. no I didn't measure them but they are bigger than any std 120 I have seen. So make sure you have the room.
I have one on the front of my case with my radiator anyone got any ideas of how to cut a door in the front of the plastic so I can put a filter on the thing and have easy access to clean it?
Hey I can cut one and put some hinges but am afraid it will look like hell.
