[SOLVED] Which header?

[Tartarnos]

I motherboard has 2 cpu fan headers. Which one do I use? https://i.postimg.cc/g0cDJV6Q/image.jpg

CPU_FAN should be your first choice (left), the CPU_OPT header is for coolers with more than one fan.
Overall they will both do the same thing.

Thanks for the help. What does the “heatsink1” mean?

Its just labeling the VRM heatsink thats right underneath it.
