I have an MSI B450 AMD Motherboard Gaming Plus Max and I use 1 built-in case fan for the back and 2 fans with white LEDs I bought for the front, all 120mm. The back one has a 3 pin slot and the other 2 have a 4 pin slot each. I have them all connected to the motherboard, the front ones on sys_fan 1 and 2, the back one on sys_fan 3. Keep in mind, I don't have a graphics card yet (and missed out on the RTX 3070), but everything else in the pc runs, such as LEDs on the mobo, but nothing about the fans work.
Can anyone help me? Feel free to ask questions that will help resolve this, thanks
Edit: I haven't installed windows yet or updated BIOS, but idk if I need to, and my power supply is 650W and 80 plus Bronze certified.
