If you want to try the script, ask again if you want help with explanations on how to customize it for your hardware. At the end, the script sets the fan header back to automatic control. It prints something that looks like a CSV text file. It measures the speed signal for a few seconds at each step. It goes through different PWM signals from 0% to 100% in 5% steps. This script takes manual control of a fan header. If you are interested in doing some experiments, I have a test script that does manual control for a fan header and prints the fan speeds: The manufacturer advertises that fan model as 1600 rpm. I have two fans of the exact same model where one of them does about 1650 rpm and the other one about 1550rpm. This would be 17% off compared to 1500 rpm. That 1250 rpm you are seeing sounds a bit extreme. Something like 5% different speed is normal. In my experience, the fan speed can be off a bit in practice compared to what the manufacturer is promising. Maybe it's actually a 1200rpm fan and is labelled wrong? I would guess there's a mistake somewhere and it's not really a 1500rpm fan. I just want to validate how to spin the fan up to 1500 RPM at high temps and why it doesn't seem to do it.ĮDIT2: Might have had a wrong source, BIOS has a test button to set it to 100% and there it caps out at 1250 RPM it says. I am using Arch linux on my Acer Nitro AN515-45 laptop neofetch OS: Arch Linux x8664 Host: Nitro AN515-45 V1.06 Kernel: 5.17.4-arch1-1 Uptime: 41 mins Packages: 1038 (pacman) Shell: bash 5.1.16 Resolution: 1920x1080 WM: i3 Theme: Material-Black-Cherry-4.0 GTK2/3 Icons: Oranchelo GTK2/3 Terminal: alacritty CPU: AMD Ryzen 5 5600H with Radeon Graphics (12) 3.300GHz GPU: AMD ATI 05:00.0. I saw some forum posts that said one has to disable BIOS-smart-fan, but I'd like to keep the bios fan curves if possible. states how to set it up, but doesn't mention how these systems usually work. Sooo, how does fan speed control actually work on archlinux? Do I have to set it up myself? Does it actually override the BIOS fan control? and the CPU hits 92C sensors claims that fan2(I can only guess it's the CPU fan, it matches CPU temp changes closest as far as I can tell) only runs at 1250RPM. However, when I run a compute-heavy task(e.g. The CPU fan should be at 100% speed starting at 80C. NBFC: I installed nbfc-linux and followed instruction on its github but unfortunately their is not auto generated configs for my laptop and the recommended configs are these Xiaomi Mi Book (TM1613, TM1703)Īnd i have no idea which one to select or even if i should run config of another laptop.I have fan control curves set up in my bios. Īnd so I cannot do anything with lm_sensors. Loading configuration from /etc/fancontrol. usr/bin/pwmconfig: There are no pwm-capable sensor modules installed Physically verify that the fans have been to full speed However, it is ** very important ** that you The program will attempt to restore each fan to full speedĪfter testing. We will attempt to briefly stop each fan using the pwm controls. Note that many motherboards do not have pwmĬircuitry installed, even if your sensor chip supports pwm. This program will search your sensors for pulse width modulation (pwm)Ĭontrols, and test each one to see if it controls a fan on Is this and their is no fan sensor and so their is no # pwmconfig version 3.6.0+git This is relatively common on laptops, where thermal management isĪnd so the only output i get from $ sensors TL DR it says Sorry, no sensors were detected. Note: More documentation is at the GitHub repository. Installation Install the lmsensors package. This document explains how to install, configure, and use lmsensors. I looked on the Fan speed control page in Arch Wiki and followed it.įancontrol (lm-sensors): Running # sensors-detect lmsensors (Linux monitoring sensors) is a free and open-source application that provides tools and drivers for monitoring temperatures, voltage, and fans. I am not sure if the fan is ramping up to 100% so i wanted to control the fan speed. UEFI can be updated through the UEFI though. Firmware Use Windows to update UEFI and GPU firmware. You may have to use the npm0 kernel parameters if you are experiencing GPU crashes. Install Arch Linux as usual using UEFI installation method.
