The board usually features a 4-pin CPU fan header, but the BIOS control for it is minimal.
Solution from manual (p. 27): Pin 1 is VCC, pin 2 is Data-, pin 3 is Data+, pin 4 is Ground. Do not connect the missing pin 5. Many cases use a 5-pin block – align the blocked hole with pin 1.
Before diving into the manual’s contents, confirm you have the correct revision. The MS-7613 has several versions (1.0, 1.1, 1.2). Version 1.1 is identifiable by: ms-7613 ver 1.1 motherboard manual
Note: The manual for Ver 1.1 is largely backward compatible with Ver 1.0 but may differ in FSB support and front audio pinouts.
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. Beep codes or POST LEDs:
