Description
Hello, everybody!
I am a huge fan of FanControl (no pun intended). However, I am having a slight problem.
Right now, FanControl is only displaying 2 out of 3 fan headers on my motherboard (not counting the CPU header).
In FanControl, I see a total of 4 fans I can control: the GPU fan, the CPU fan, and 2 motherboard fan headers, but the third one is missing.
I have a Gigabyte GA-B150M-D3H motherboard. https://www.gigabyte.com/Motherboard/GA-B150M-D3H-rev-10#ov
In the bios, I can configure the third header, however, I am unable to find the third header with your software.
I will attach a screen shot of how it looks on my end. You will see that I am not using the GPU fan to cool the GPU, I am instead using a normal case fan strapped to it and plugged in into a motherboard header.
Can you help me out with this?
Thanks in advance!

Research direction
Reproduce the missing-header report on the Gigabyte GA-B150M-D3H, using the motherboard details and attached screenshots as the starting evidence. The issue names no source files, tests, or entry points; done would mean identifying why the third header is absent and confirming that FanControl exposes it without breaking the existing fan controls.
