Can't detect/control 3rd GPU fan

[PsychotropicPineapples]

I have an EVGA RTX 3080 XC3 Ultra, which has 3 fans. I know FanControl normally detects 2 fans and that typically fan #3 simply follows the same speed as #2, but that doesn't seem to be the case with my card. I can control 2 of the fans with separate controls in FanControl, but the third fan will still use whatever speed it was set to within EVGA Precision X1. I was thinking maybe it just wasn't showing the speed correctly in X1, so I set the speed of the fans to 0% in X1 before setting FanControl to take over control of the fans. The first two span up to the speed I'd set, but the third still showed 0%. I looked inside the case and verified it, still only 2 fans spinning.

Have I perhaps set this up wrong so that X1 is still forcing control of the third fan, or maybe EVGA fans are controlled in some different manner?

Well, now I feel kinda stupid. After posting this, I then mucked around with changing settings in X1, enabling/disabling control within FanControl, etc.. At first it was acting the same as before, but at some point I noticed that fan #3 was changing. It was slow, but after a few seconds it would start to slowly shift its speed toward whatever #2 was set to. It'd then take several seconds more to eventually reach it, but was definitely setting itself to the same speed.
Somehow this wasn't how it was working before, since the time it took me to get #1 and #2 spinning and #3 stopped and then crawl on the floor with a light to check the fans manually was more than enough for #3 to also match the speed of #2.
I was just changing every setting available, so I don't know if there was something I did or if jumping back and forth between settings just somehow got it to work(like the classic 'turn it off and on again' fix).
