Derezzer Case Fan Setup
The stock fans are being replaced (except for the 200mm front intake) with eight Enermax TBSilence 120mm case fans. These fans provide a little better performance and quieter operation. Three exhaust fans are mounted on top, with three more intake fans located in the lower storage zone; two intake fans are also mounted on the side door to cool the GPU area. Just in terms of fan capacity, the lower storage zone has slightly net-positive air pressure; the main upper zone has slightly negative pressure. Overall, the case has more intake capacity than exhaust, making the build a positive air pressure design.
To help minimize vibration, Nexus silicon fan mounts are used throughout the case. One 140mm BeQuiet! Shadow Wings PWM fan is mounted in the rear of the case, and three more BeQuiet! fans will eventually be mounted directly on the Noctua NH-D14 heat-pipe. All the case fans will be controlled using the Cosmos II controller, except the BeQuiet! rear exhaust and heat-pipe PWM fans, which will be controlled by the CPU-FAN header.
