ok cool. So I will just have 2 Noctua fans in the box, and remove the one from the back and just keep that and the budget fan that came with the H55 in a box somewhere?
That's the idea. Ditch the garbage fans for the better silent fans. It also blows all that heat directly out the back of your case rather than it just sitting in there waiting on airflow to blow it out.
I turned the server off overnight and this morning it was running for 2-3 hours and the fans were at 2000 rpm. Was like a mouse in the corner, was a beautiful sound!
