I have had my Norco 4220 case with stock fans for many years that was in another room away from anyone to hear the loud fans.  I have since had to relocate it where it can be heard and it sounds like a jet engine.  I wanted to see if any of you still use this case and if you have any suggestions to help reduce the loud fans.  I did goggle it and read old stories about a bracket to replace the center 80 cm fans with 120 cm fans.

 

Thanks,

Here's what I did...

1. Replaced the two stock rear 80mm twin axle fans, with Noctua NF-A8 PWM 80mm . Simple and good first place to start.
2. Find and order the 120mm center bracket. I've used two kinds of fans in this setup
   1. NF-F12 iPPC 3000 PWM -- Loud, but they move some air! If you have fan speed control you can adjust 50% to be the same as option 2. This is what I use now.
   2. Noctua NF-F12 PWM -- Quiet, I found when I got 7200RPM drives or more than 16 drives in the case that I needed more speed. I no longer use these.

One tip to always keep the top cover of your case on when the system is on, the fans need the static pressure to pull air in through the front of the case.

 

 

There's actually 2 editions of the 120mm fan wall now I found out

The old standard one, and the new one with hot-swap 120mm fan cages which I was lucky to get with mine
