2023年12月24日 · CPU_OPT (also CPU_FAN2, etc.) stands for "CPU Optional" and is a four-pin fan header for a secondary CPU fan found on large air coolers. CPU_OPT has only three pins on some cheaper motherboards, which means it can lack PWM fan control.

2022年12月12日 · What is CPU OPT (CPU_OPT)? CPU_OPT, standing for “CPU Optional”, is mainly used when you have more than one fan on your cooler/radiator, and you need someplace to plug it in. Essentially it’s CPU_FAN without the “not booting if nothing is connected to it” part.

2022年5月2日 · What is CPU_OPT? A motherboard’s 4-pin CPU_OPT (‘CPU Optional’) header is its optional header for plugging in CPU fans. If your CPU cooler uses two different headers, you can plug the main one into your CPU_FAN header and the other one into your CPU_OPT header.

2024年4月15日 · CPU OPT only supplies power to the connected device, while CPU FAN both supplies power and communicates with the motherboard’s BIOS or UEFI system to provide statistical data.

2024年7月19日 · What is CPU_OPT? CPU_OPT stands for CPU Optional Fan. As the name suggests, it is an optional header/connector for additional cooling fans. If you have a large aftermarket heatsink with dual-fan CPU coolers, then we have to connect the secondary fan to the CPU_OPT header.

2024年5月30日 · Let's find out the difference between the CPU_OPT and the CPU_FAN headers, and see which one to connect your CPU cooler to.

2024年1月6日 · CPU_FAN and CPU_OPT are entirely different and serve distinct purposes in the context of a computer cooling system. CPU_FAN or CPU Fan Header is the primary 4-pin fan header on a...

2025年1月24日 · CPU OPT is a special connection for the motherboard to keep the CPU cool at all times. So, it is better to use CPU OPT only for fans. If you connect the AIO Cooler to CPU OPT, ensure that the radiator is connected to CPU FAN.

Compare CPU_OPT and CPU_FAN connectors to find out which is best for your PC cooling needs. Get the right setup that delivers optimal performance.

2023年10月4日 · CPU FAN and CPU OPT are two headers that you can find on a motherboard. These headers allow you to connect cooling fans to your computer, but what's the difference between the two? This guide will tell you the differences and why it's important to know them.
