Sure! To connect your CPU fan, locate the designated port on your motherboard—usually a small slot near the CPU or integrated into the case. For an ASUS Z97 Pro gaming build, check the manual or manufacturer’s guide to confirm the exact port type (like PCIe or USB). Once you find it, gently push the fan into place and secure it. If you need a visual guide, I can describe how to position it correctly.
The fan header is located above the initial RAM slot marked as CPU Fan. You should connect it there unless you turn off the BIOS alert for detecting zero RPM.
Spoiler from the manual details troubleshooting steps and system guidance for users.
CPU Out refers to the CPU OPT setting, meaning Optional. When using a dual radiator or a cooler with two fans, you'll find two headers close together for easier cable routing and organization. CHA Fan is simply the Chassis Fan, which are additional headers often used for case fans or those mounted on the chassis.
Yes, it's just the name, but it can apply to any fan. The main header for a motherboard that matters is likely for water pumps because they often have a higher amperage rating than typical ~1A headers for fans. You don't need to use the CPU fan header if you're not using it. Just open the BIOS and tell it to ignore it, otherwise it will show a CPU fan speed error each time you restart during POST.
