I recently upgraded to a new case, a Corsair Frame 4000D, and added 8 Arctic P12 fans. They're all connected through an Arctic fan hub, but I've noticed they're running at full speed all the time, making a lot of noise. I tried adjusting the fan curve in the BIOS but didn't have any luck. I also experimented with the DC mode, but the fans still won't slow down. Can someone suggest how I might control their speed or what other options I have? Thanks!

Just to clarify, is the Arctic fan hub powered through USB or a SATA connection? That can make a difference in how you control your fan speeds.
If you’re trying to control the fans through the BIOS, make sure to plug them into your motherboard headers directly instead of using the external hub. That way, you can adjust the fan speeds properly. You could also connect the fan hub to a motherboard header, but be cautious about overloading it with too many fans. Check both your motherboard and hub's manuals to see their limits. Good luck!
It’s actually powered by a SATA cable.
The hub is connected to my motherboard fan header 1. I’ll check if having 8 fans is too much for that port, but I hope it’s fine. The BIOS shows the fans running at 1600rpm.
