I love to help with technical stuff when I can! I miss that from reddit, everyone on lemmy are so darn tech-knowledgable (or know how to google) that they never ask for help. So until it becomes necessary to put it in its own comm, asking here seems like the right thing to do. Don't know how much I can help with water coolers though. I have given up on them. I went through four different AIO coolers, everyone of them either died or became ridiculously noisy before half a year went.
But fan connections are very simple. There is no drivers. Just 4 pins (or 3 pins) and if the bios doesn't recognize them, then either its something wrong with the motherboard or the cooler. And if a regular fan works on the mboard, and your cooler doesn't, i would figure the cooler is at fault and ask for a replacement.
