@colingmo @68Electra Since there's really only two fans for the whole system, it isn't very loud. I opted for a 120mm fan at the top for better airflow at lower rpms (less noise). The 90mm Noctua fan on the CPU cooler is occasionally audible at high load.
@Cang @aquelito Further explanation of the GPU power delivery: The 12V+ supply coming into the board needs to come from one source to prevent the power supply from feeding back onto itself. Since there are technically two 12V sources in the system, the motherboard's 12V regulator and the 12V PSU itself, I need to power the video card from only one of these sources. The relay here switches 12V feeding into the PCI-E connector & 6-pin of the GPU. It is triggered by the 12V rail on the PCI-E slot on the motherboard. The riser cable is the only thing modified.
The riser cable is modified as such:
-PCI-E Pins Side A 2,3 and Side B 1,2,3 on the riser are disconnected (Pinout available here)
-These pins from the Motherboard side on the riser are spliced to feed into the trigger side of the relay
-The same pins on the GPU side of the riser are fed from the 12V Output of the Relay.
-The GPU is now powered via the Relay, not directly from the Motherboard
Here's a visual overview of what's going on:
