Insufficient headers for AIO setup
Insufficient headers for AIO setup
He PC isn't heating up as expected despite high temperatures. The fan headers seem mismatched—connecting them to the wrong pins. The schematics suggest using the CPU OPT header, but you're using the SYS FAN and set it to CPU control in BIOS. Try swapping the fan headers to match the correct pinouts. Also, ensure the radiator is properly seated and the AIO is functioning correctly. If issues persist, check for any loose connections or faulty components.
Link the block/pump to the CPU header, and connect the fans to the System fan header. Adjust the CPU fan header to full speed and let SYSFan operate normally; Auto is acceptable. This setup should keep your pump running smoothly and prevent your radiators from overworking. I applied this on an older system lacking proper AIO connectors, following a similar thread, and it performed well with quiet operation and stable temperatures.
For watercooled setups it's best to leave the CPU fan header unconnected since it's tied to CPU temperature control for fan speed. Plug the AIO into the dedicated AIO fan header, or use the chassis 1 header if available. You can fine-tune fan curves with AORUS or Gigabyte software. To prevent BIOS warnings, you may need to disable monitoring on the CPU fan header. Alternatively, using a fan controller with a single PWM cable to the mainboard could simplify management.
I used ben's approach and the ramping isn't happening yet, so everything's okay. I'll adjust the fan settings in BIOS if things get too hot. Thanks!
