Hello everyone, I recently purchased a system with Ryzen 7 3700x, Asus TUF B450M-Pro Gaming, Thermaltake TH240, RTX 3060ti.

My problem is, after I set up every part and turn the PC on, the fans always turns full rpm. AI Suite 3 shows every fan N/A, and in BIOS whatever I do fans stay Full RPM.

What should I do?

Did you check settings in BIOS and made sure CPU_FAN header is set to DC/Voltage ?
Yes I had two options in bios, PWM and disabled for CPU Fan. Neither does anything. What I noticed is, even if I manually try to change fan curve system only lets me use a minimum of 86% fan speed.
