Aio - Corsair H115i Pro RGB Motherboard - Trouble with Asus X470-F Gaming. One of the cables from the cooler has a CPU 3-pin connector, but the board seems to only have 4-pin connectors. Where should I find it? Thanks!

Connectors for four pins work with both three-pin and four-pin fans.

What model mono is it?

You connect the 3-pin to your 4-pin CPU header. The device fits only in one orientation due to plastic spacers on the cable and connector. The fourth pin is optional, as is the third pin. The first two pins along with the plus and minus signals, plus voltage measurement for speed adjustment, and the fourth pin for PWM control—all are compatible with modern boards. Using a 4-pin header works just as well.

The third setting is measured in RPM. Adjusting the voltage occurs on the two power pins. The third option remains optional; without it, the speed isn't visible.

You should connect it according to the instructions in the manual—either the AIO pump fan header or the CPU fan header. Check the documentation for clarity.

The instructions suggest linking it to the CPU_FAN port. That makes sense. A motherboard often requires a connection there for optimal performance, and I've noticed that pump header connectors can vary in design.

It's good to hear. You likely won't need to adjust anything in the bios. This is your first liquid cooler, and you've already tried the included Wraith.

Besides the fan curve, there isn't much else to change. You can keep it as is, but it might sound too loud. To tweak the pump speed, switching from PWM to DC control usually helps.

It seems to be just the sense pin, likely intended to prevent the motherboard from complaining about the absence of a CPU fan. The fan curve and PWM/DC adjustments won’t apply here.
