The design error of the Corsair 900D

There's a very complex balancing act between the number of fans and the rotational rate of those fans, however. Additional fans increase noise just as increased RPM increases noise. Have you crunched the numbers on all of that?

What the hell hardware are you guys putting in these cases that needs dual 480 or 560 rads

Overkill for most people, but I run dual quads because I have a TEC block that adds a ton of heat to my loop. With a triple and dual in series my water temp was still ~6c above ambient just at idle. With the dual quads, my water temp is ambient at idle.

Adding more quiet fans is way less dramatic then a lower amount of noisier ones. My tower has 21 120mm fans now, but is quieter then it was with only 5 high CFM 38mm Delta's.
