" rel="nofollow - Hi Everyone, I've recently installed 4 Noctua 4pin/pwm fans and cannot control the speed via BIOS/A Tuning. It looks like the fans are not being detected at all. I have 1 plugged into the CPU Fan 2 and the other 3 in the chassis fan slots. The bios is showing some crazy readings in the summary such as 655635 RPM for all the fans and are not being detected in A-Tuning/Speedfan. Atuning shows 0 RPM for all fans even though they are going full speed. SpeedFan is only detecting the GPU fan. I've flashed the BIOS to the latest 1.50 as well. Ryzen 2700x G.Skill 16GB 3200mhz RX480 960 EVO NVME Is this a faulty board? Am I missing a driver? Any guidance would be appreciated.

I have the same issue on X370 Taichi and I don't Know the reason. I was thinking it was some UEFI problem. Max speeds are over 16000, 24000 and 60000 rpm - Noctua F12 PWM CPU fans (no way 0 rpm)and others Arctic 14cm PWMs. Also min voltages = 0??!! I don't believe VRMs were at 96 C. https://ibb.co/cSKQpT ------------- ASRock Taichi X370 UEFI v4.81; AMD Ryzen R7 2700X; Noctua NH-U12S x2 fans; Corsair Vengenace LPX 3000 2x16GB (CMK16GX4M1B3000C15); EVGA GeForce GTX1070 FTW; Corsair RM750i PSU |

Thanks all, I completely stripped everything and put it back together (nothing changed except CMOS reset) and it started working... sometimes a fan or two will completely not spin if I put it on SILENT fan mode. If I put them on custom/standard they all spin at their expected speeds. I honestly have no idea what did it but am not complaining. I even requested an RMA which I don't need now so i'm stoked about that. Appreciate the replies and if I encounter anything else I will come back and try kerberos's suggestion.
