The MS-7613 monitors the CPU fan speed closely. If you plug the CPU fan into a "System Fan" header instead of the "CPU Fan" header, the BIOS will halt the boot process claiming a fan error. Ensure the CPU cooler is plugged into the 4-pin header near the CPU socket.
The MS-7613 Ver 1.1 remains a capable board for light office work, retro gaming, or a budget NAS build. By understanding its specific LGA1156 limitations and the quirks of its OEM BIOS, you can keep these machines running for years to come.
