I have modified the SDR file for my custom build.
Here's my build post:
Dual E5-2670 build in the smallest case NZXT S340
Here's some background information: The SDR file is quite complicated in a sense that there are a handful of sections you need to edit to be able to achieve controlling the FAN speed based on a different thermal sensor and curve profile. If you use the custom xxxx_RAMP profile, then all fans rely on the single thermal sensor called BB_EDGE to vary their PWM values. This sensor reacts quite slowly so in my case, having noctua fans running at 600RPM and sloooowly ramping up is not enough. I needed the CPU fans to react quickly when the CPU is loaded. After some modification, I have linked the P2_VR sensor to both CPU fans, it approximately matches the CPU temperature and reacts pretty quickly.
I have uploaded my modified SDR file for you to compare. It sets FAN speed based on my all noctua configuration.
CASE FAN 1: NF-P14S Redux PWM-1200 RPM
CASE FAN 3: NF-P14S Redux PWM-1200 RPM
CPU FAN1: NF-F12 PWM-1500 RPM
CPU FAN2: NF-F12 PWM-1500 RPM
REAR FAN: NF-P12 PWM-1300 RPM
