Noise from the x570 PCH fan is common.
You're experiencing heat issues with your ASUS TUF x570 WIFI setup. The PCH fan is working hard right behind the GPU, drawing in hot air and spinning above 3000 RPM. While a 140mm case fan below helps, it isn't enough. You've tried software like FanControl, but it crashes when temperatures rise and doesn't support BIOS tweaks. Switching to a B550 board could be a significant change, but it might offer better cooling if you're open to upgrading your hardware. Your current specs include a Gen 4 SSD and an R7 5800X—consider whether these are compatible with the new board before proceeding.
I picked a B550 simply to skip one of those fans and because I didn’t need the additional options. With a 5900X, a Gen 4 SSD, and an RTX 3080 running Gen 4, I’ve faced no problems. As long as you get a high-quality B550 with solid power delivery and VRM heatsinks and you don’t require multiple Gen 4 SSDs at once, you should be fine. I think fanless X570 models might be worth considering now. There could also be a method to turn off the PCH fan, but I’d avoid that risk.
