I have this mainboard, and while it works great, i have one problem. Right now i am trying to get fan control set up in linux, and the board does report all connected fan speeds as 0. In windows with speedfan, everything works fine, but i just can't figure it out in linux. Can someone help me please? |

hi, you've to install lm-sensors and configure it with sensors-detect. Then sensors will display all it finds. For a real time monitoring you've to install an applet, depending on your distibution ------------- AMD Ryzen 7 2700X w/Wraith prism x470 Taichi bios 3.50 16gb HX432C16PB3K2/16 (hynix H5AN8G8NCJR-UHC) M.2 970 EVO, SATA SSD, 2 SATA HDD AMD Radeon RX 580 8G OC Linux Kernel 5.4 Manjaro Stable XFCE |

sorry, I misread. are the fan connected with the old big connector (molex, two wires) or little one (3 or 4 wires). The first one doesn't report the fan speed ------------- AMD Ryzen 7 2700X w/Wraith prism x470 Taichi bios 3.50 16gb HX432C16PB3K2/16 (hynix H5AN8G8NCJR-UHC) M.2 970 EVO, SATA SSD, 2 SATA HDD AMD Radeon RX 580 8G OC Linux Kernel 5.4 Manjaro Stable XFCE |

 my little phone...if it works in windows then isn't a connector matter. so try with lm-sensors etc ------------- AMD Ryzen 7 2700X w/Wraith prism x470 Taichi bios 3.50 16gb HX432C16PB3K2/16 (hynix H5AN8G8NCJR-UHC) M.2 970 EVO, SATA SSD, 2 SATA HDD AMD Radeon RX 580 8G OC Linux Kernel 5.4 Manjaro Stable XFCE |

lm-sensors is installed and working, and the other readings look fine. I can see the temps and all. But the fan speeds are all reported as 0 RPM. It uses the nct6776-isa driver.

May be uou have an hub for the fans? Or connector is splitted? You've to wait fot amd tech otherwise ------------- AMD Ryzen 7 2700X w/Wraith prism x470 Taichi bios 3.50 16gb HX432C16PB3K2/16 (hynix H5AN8G8NCJR-UHC) M.2 970 EVO, SATA SSD, 2 SATA HDD AMD Radeon RX 580 8G OC Linux Kernel 5.4 Manjaro Stable XFCE |

I do use splitter cables. All 4 fans on my 240mm liquid cooler are connected to the CPU fan header, for example. The main point is that i want to control the CPU fans based on core temps, and also system temp. Since these fans are not only cooling the CPU radiator, but also push air into the case, i want them to be controlled based on multiple temps. This was not too hard to achieve with speedfan on Windows, but i don't know how to achieve the same on linux. To be honest, i would accept that i don't see the RPM. I don't care too much about that. But i really need to be able to control the PWM outputs with multiple temp sources and custom fan curves. ------------- AMD FX-8350 ASRock 970A-G/3.1 16GB DDR3 1600 XPG S11 256 GB M.2 SSD Sapphire Nitro+ RX580 4GB (+ a total of 7 120mm fans wich are annoyingly loud because i can't get fan control working in Linux Mint) |

for what I know lm-sensor is non compatible with splitter, google that. I think it can read graphic card fan rpm (that have 2 or three fans) because despite they are splitted, the graphic card itself give a reading to the sensor that lm-sensor reads. In your case there isn't, I suppose, such intemediary, so lm-sensor give up. The bios has only 1 curve (at least on my board). ASRock mobos, for what I read here, work actually only with tCtrl parameter (i.e. tDie plus a fix offest of 10°C) despite there are two more parameter in fan control bios options. That said, that's a big limit, for your need I'd see "fancon" or other projects. Do you see readings in bios. If yes then you can configure there your fan, with the limit of one curve per fan. In my case I use lm-sensor to read while the curves are set in bios and it works as I want. ------------- AMD Ryzen 7 2700X w/Wraith prism x470 Taichi bios 3.50 16gb HX432C16PB3K2/16 (hynix H5AN8G8NCJR-UHC) M.2 970 EVO, SATA SSD, 2 SATA HDD AMD Radeon RX 580 8G OC Linux Kernel 5.4 Manjaro Stable XFCE |

for istance, to have a low noisy system, with positive pressure inside the case I set the fans as follows (extract form my work sheet) Cpu1 Cpu2 Cha1 Cha2 Cha3 Delta CoolerM Adda Vultech Criogen Vultech 1 step tCtrl 60 60 60 60 60 °C rpm 30% 40% 30% 90% 30% cfm 17 (29) 12 40 (12) 27 2 tCtrl 70 70 70 70 70 °C rpm 50% 50% 50% 90% 50% cfm 28 (36) 20 40 (20) 31 3 tCtrl 80 80 80 80 80 °C rpm 70% 70% 70% 90% 70% cfm 39 (50) 28 40 (28) 28 4 tCtrl 90 90 90 90 90 °C rpm 100% 100% 100% 100% 100% cfm 55 (72) 40 44 (40) 27 ------------- AMD Ryzen 7 2700X w/Wraith prism x470 Taichi bios 3.50 16gb HX432C16PB3K2/16 (hynix H5AN8G8NCJR-UHC) M.2 970 EVO, SATA SSD, 2 SATA HDD AMD Radeon RX 580 8G OC Linux Kernel 5.4 Manjaro Stable XFCE |
