The reason why that header is important is because it will detect whether your fan is running are not. If it detects the fan is not running or not running properly, it will shut down your system or refused to start your system to protect your CPU from overheating.
The CPU OPT stands for CPU optional. Typically, this is the header that you would use to connect some type of wiring for a liquid cooling system. For example, I have two pumps running my liquid cooling two separate loops.
Each one of these pumps has a single wire that I can plug into the CPU OPT header. However if I decided to plug those connectors into the motherboard, it would probably allow me to control the speed of the pumps from the motherboard which brings me back to the CPU FAN. Most gaming motherboards will allow you to control the speed of the heatsink fan that is connected to the CPU FAN header.

System Fans aka SYS fans are regulated by the temperatures on the Motherboard or run at a specified rate. CPU FAN is the connection for the primary fan on the CPU cooler.
As some coolers have two fans one push, one pull the CPU OPT allows connection for the second fan. SYS FAN can be any fan in the box that you want to connect to the motherboard so that it is monitored by the BIOS.
In the BIOS settings, you will find options for speed control and alarms for these fans. If you have not used the CPU OPT or the SYS FAN connector, make sure that the relevant alarm is disabled.
