Unfortunately I live in the US and due to reasons (tariffs) the creator of the open fan is currently not selling to US customers. So this is not an option currently for me. Bummer... If you can get one pwm fan header to work, then split it and use this https://www.amazon.com/Thermalright-Integrated-10-Port-Controller-Support/dp/B09CH31RM6/ If not then maybe CORSAIR iCUE COMMANDER CORE XT Neither worm as good as an OpenFan Or better yet, see if you can find an OpenFan used... Or maybe have it to delivered to a friend somewhere else, maybe Mexico or Canada, then go pick it up from there... Or order it for hotel delivery on your next business or hotel trip.
August 23, 2025Aug 23 i dont know if this is a good place to look for help.Hello .. been playing around with the IPMI and I can not under understand. I don't seem to be able to edit anything. the IPaddress is there and i have entered the username and password. I know the username and password it good.I am using a SuperMicro :Supermicro X9QR7-TF+/X9QRi-F+ , Version 123456789American Megatrends Inc, Version 3.0aBIOS dated: Thu 3 Apr 2014 12:00 AMNo sure will it work with my computer setup. i have looked for any fan drivers from supermicro but could not find anythihng yet, if not any thoughts.Thanks John G.

October 26, 2025Oct 26 Hello,I am having weird issues with PWM, and fan speed sensors. I expect it is related to the drivers. How to find out which driver I need to use? System temp plugin detects it87 k10temp. However I am having weird issues.I have 3 fans connected on different mobo headers. Sys fan 1,3, CPU. Issues:Unraid only detects fan speed for sys fan 3.PWM control only works at 1000 - 1700 rpm. Fan does not slow down bellow 1000 rpm.Mobo: Gigabyte aorus b550 v2I expect that my issues are due to wrong drivers?I'd like to be able to see all 3 of my fans and have my case fans spin up only when my disks are active... FanCtrl plus seems perfect for this task yet my fans do not spin down bellow 1000 rpm...pwmconfig command returns the folowing:Found the following devices: hwmon0 is acpitz hwmon1 is k10temp hwmon2 is nvme hwmon3 is nvme hwmon4 is nvme hwmon5 is it8792 Found the following fan sensors: hwmon5/fan1_input current speed: 0 ... skipping! hwmon5/fan2_input current speed: 0 ... skipping! hwmon5/fan3_input current speed: 1695 RPM Testing pwm control hwmon5/pwm3 ... hwmon5/fan3_input ... speed was 1695 now 1136 It appears that fan hwmon5/fan3_input is controlled by pwm hwmon5/pwm3 Would you like to generate a detailed correlation (y)? y PWM 255 FAN 1358 PWM 240 FAN 1149 PWM 225 FAN 1083 PWM 210 FAN 1053 PWM 195 FAN 1040 PWM 180 FAN 1036 PWM 165 FAN 1027 PWM 150 FAN 1022 PWM 135 FAN 1022 PWM 120 FAN 1019 PWM 105 FAN 1018 PWM 90 FAN 1018 PWM 75 FAN 1019 PWM 60 FAN 1021 PWM 45 FAN 1016 PWM 30 FAN 1010 PWM 28 FAN 1008 PWM 26 FAN 1018 PWM 24 FAN 1019 PWM 22 FAN 1016 PWM 20 FAN 1011 PWM 18 FAN 1010 PWM 16 FAN 1002 PWM 14 FAN 1016 PWM 12 FAN 1016 PWM 10 FAN 1013 PWM 8 FAN 1010 PWM 6 FAN 1007 PWM 4 FAN 1004 PWM 2 FAN 1005 PWM 0 FAN 1011 And sensors output:root@DataServer:~# sensors nvme-pci-0100 Adapter: PCI adapter Composite: +31.9°C (low = -273.1°C, high = +84.8°C) (crit = +84.8°C) Sensor 1: +31.9°C (low = -273.1°C, high = +65261.8°C) Sensor 2: +26.9°C (low = -273.1°C, high = +65261.8°C) nvme-pci-0400 Adapter: PCI adapter Composite: +32.9°C (low = -0.1°C, high = +74.8°C) (crit = +79.8°C) acpitz-acpi-0 Adapter: ACPI interface temp1: +16.8°C it8792-isa-0a60 Adapter: ISA adapter in0: 1.79 V (min = +0.00 V, max = +2.78 V) in1: 589.00 mV (min = +0.00 V, max = +2.78 V) in2: 1.04 V (min = +0.00 V, max = +2.78 V) +3.3V: 3.38 V (min = +0.00 V, max = +5.56 V) in4: 1.79 V (min = +0.00 V, max = +2.78 V) in5: 1.50 V (min = +0.00 V, max = +2.78 V) in6: 2.78 V (min = +0.00 V, max = +2.78 V) ALARM 3VSB: 3.36 V (min = +0.00 V, max = +5.56 V) Vbat: 3.23 V Array Fan: 1018 RPM (min = 0 RPM) temp1: +34.0°C (low = +127.0°C, high = +127.0°C) sensor = thermistor temp2: -55.0°C (low = +127.0°C, high = +127.0°C) sensor = thermistor temp3: +34.0°C (low = +127.0°C, high = +127.0°C) sensor = thermistor intrusion0: ALARM nvme-pci-0500 Adapter: PCI adapter Composite: +35.9°C (low = -0.1°C, high = +74.8°C) (crit = +79.8°C) ERROR: Can't get value of subfeature temp2_min: I/O error ERROR: Can't get value of subfeature temp2_max: I/O error Sensor 1: -226.2°C (low = +0.0°C, high = +0.0°C) ERROR: Can't get value of subfeature temp3_min: I/O error ERROR: Can't get value of subfeature temp3_max: I/O error Sensor 2: -239.2°C (low = +0.0°C, high = +0.0°C) ERROR: Can't get value of subfeature temp4_min: I/O error ERROR: Can't get value of subfeature temp4_max: I/O error Sensor 3: -237.2°C (low = +0.0°C, high = +0.0°C) k10temp-pci-00c3 Adapter: PCI adapter CPU Temp: +34.2°C MB Temp: +32.0°C Any tips as to what I should look into?

Fan does not slow down bellow 1000 rpm.Any tips as to what I should look into?The RPM of a fan it's driven by it's design. Not all of them go down to low or zero RPM. I am dealing with this today, got numerous that would not go below 750rpm. Without restarting the system or changing any settings,I swapped it for Noctua NF-P12 redux-1300 PWM and it manages to drop to 0 RPM. That fan spec specifically says from 0 RPM, that is why I bought it. Many other models don't go down to zero.Typical CPU fans, especially the cheap ones bundled with CPU have about 1000RPM minimum. Also, the higher the power/max RPM, the lower the chances it will spin down to zero RPM.I do see that you have a chip it8792 - this is what lead me to this post. I have the same chip controlling 3 of my 6 fans and I can't get it to control speed at all thru unRaid 9but they do report RPM). My other 3 are on it8688 and I have full control of them Edited December 27, 2025Dec 27 by OrdinaryButt

My other 3 are on it8688 and I have full control of themI know the limitations of fan RPM and I know it is not the case as the same fans were plugged on different headers yielding different results. Issue was due to it8792 chip and its implementation on unraid. I just switched to a header that is on it8688 which solved all of the issues. So most likely case is that the driver has an issue with this chip.Regarding fan speed not displaying - apparently playing around with PWM causes issues with the driver which in turn can brick systemp temps plugin from loading the proper driver to display RPM. System restart usually fixes that...Anyway summary for PWM on unraid - pray that it works and don't touch it if it does. If it does not - 1st try server restart.
