What Is CPU OPT?

CPU opt meaning is CPU optional. It is a header that is used to connect some type of wiring for a liquid cooling system. Once connected, you are able to control the speed of the fan from the motherboard.

Most gaming motherboards are equipped with such CPU OPT for controlling the heat sink speed. when you aren’t using the PC for heavy load, you can reduce the fan speed so as to reduce the noise of your system.


Some heatsinks may pair with 2 fans or may have clips on both sides. In such a situation, one fan pushes cool air into the fins while the other fan pulls hot air out.

In general, CPU OPT is an additional CPU fan header. Since it is “additional”, it is not necessary and the system can start normally without working with CPU_OPT. that is to say, CPU OPT can’t prevent the system from booting if there is a problem. Yet, it can warn you about problems.

Can I Use CPU OPT for Case Fan?

CPU fan header, CPU OPT, and SYS fan header, if all of them are 4 pin fan headers, the motherboard, and in turn the BIOS and the OS, can control the fans’ speed. therefore, theoretically, you can connect the case fan or one of the case fans to the CPU OPT without a problem.

However, if you connect your case fan with the CPU opt header, the speed of the case fan will increase dramatically when the CPU gets hot, just like the heatsink/CPU fan connected to the CPU_FAN header will do. And, when the CPU cools down, the case will slow down.

While if you connect the case fan into the SYS_FAN header, it will change its speed accordingly by the signal coming from the thermal sensor or some software controlled by the BIOS or the OS.
