It looks like your new motherboard lacks the 4-pin fan or water pump headers you expected. The PDF manual confirms this. Since you’re using an i7-7820X and a custom water cooling setup, you can run your pump directly from your modular power supply without needing any adapter. Just connect the pump’s 4-pin header straight to the motherboard’s header pins. No conversion needed—your setup should work fine as long as the pump is properly seated.

You can employ 6-pin connectors to serve as a 4-pin PWD link for fans or pumps.

You have the C422 WS/IPMI / X299 WS/IPMI board with the 6-pin connector. You're suggesting you can likely just place the female 4-pin connector over pins 1-4, skipping pin 5 (Sensor) and pin 6 (NC). The initial four pins seem to behave like a standard 4-pin header. I'm planning to test if it will fit properly. BRB

The 4-pin female connector features ridges that prevent it from fitting over the 6-pin connector. Four out of six pins match, so I’ll sleep and think about it tomorrow. Another question: this new board includes two 8-pin power connectors—ATX12V1 and ATX12V2. My previous board only had one. Should I use both? If yes, I’ll need to retrieve another cable. Why are there two? I assumed they powered the CPU, but I only needed one on my old board. Now I’m using the same CPU? Could it be for a more demanding processor? All my GPUs are powered separately from the supply.

Yes, using EPS connectors is suitable for water cooling and overclocking.
