I've deduced that it's probably #Gigabyte's fault. I got the right CPU fan header and it's seated properly, but the fans just refuse to spin no matter what. I then reseated the fan connector, despite it visibly showing that it's already seated properly, and that got it to work - until sometime later it just doesn't anymore. This happens regardless of whether I had set the fans to spin according to my temp/fan speed curve, or making it spin at full blast all the time. As it is, it's impossible to #game since the fans won't spin at all and it'd quickly reach my PBO temp limit of 85c and throttle hard. This isn't the only issue I've encountered with this B550I #AORUS Pro AX mobo - prolly should've went with an ROG board like my primary PC.
Found a comment saying that #Noctua fans don’t play well with #Gigabyte boards. I have a spare CPU cooler I bought long ago that’s supposedly better thermally and comparable aurally with the current Noctua cooler I have installed. If I’m not feeling lazy, I might just try replacing the cooler - I can only hope that I could do so while the board’s already in the super tiny case of mine, cos getting it out and in again would be a massive pain.
TLDR; Please Avoid Buying Gigabyte/#AORUS motherboards. #MSI and #ASUS boards most of the time are preferable, maybe even #ASROCK.
I've just learned that #NVIDIA and #AMD are both American, for some reason I've always thought they were Taiwanese like a lot of the other PC components manufacturers such as #ASUS, #ASRock, and #MSI. That's kind of mind-boggling lol.
