I love Thinkpads. They are robust and durable. And no need to mention about their world class keyboards!
My newest Thinkpad comes with AMD Ryzen 4750u which is really powerful and absolutely perfect for web development purposes. With my i3 setup it works like a charm, but we need to configure it a bit for silence. Let's start!

I lately moved my development environment from Arch Linux to Ubuntu, so the following steps might differ in your distro.
sudo apt install thinkfan
After installing the package we need to create a config file in the following directory:
This file requires three main items:
- The fan information
- The temperature information
- Speed level for temperature levels
In order to provide fan information, we write this line:
For the temperature information we should scan the sensors of the device.
find /sys/devices -type f -name 'temp*_input'
Running this comman should give you something like this but without hwmon keyword. Don't forget to add it in front of each line.
hwmon /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon4/temp6_input hwmon /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon4/temp3_input hwmon /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon4/temp7_input hwmon /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon4/temp4_input hwmon /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon4/temp1_input hwmon /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon4/temp5_input hwmon /sys/devices/pci0000:00/0000:00:18.3/hwmon/hwmon3/temp1_input hwmon /sys/devices/pci0000:00/0000:00:18.3/hwmon/hwmon3/temp2_input hwmon /sys/devices/pci0000:00/0000:00:02.1/0000:01:00.0/hwmon/hwmon2/temp3_input hwmon /sys/devices/pci0000:00/0000:00:02.1/0000:01:00.0/hwmon/hwmon2/temp1_input hwmon /sys/devices/pci0000:00/0000:00:02.1/0000:01:00.0/hwmon/hwmon2/temp2_input hwmon /sys/devices/pci0000:00/0000:00:08.1/0000:06:00.0/hwmon/hwmon8/temp1_input hwmon /sys/devices/virtual/thermal/thermal_zone0/hwmon5/temp1_input
After adding these lines to the configuration, we need to add our fan speed data for each temperature level. This is a sane configuration for daily usage but use at your own risk.
# speed level | start temp | end temp (0, 0, 55) (1, 48, 60) (2, 50, 61) (3, 52, 63) (4, 56, 65) (5, 59, 66) (7, 63, 32767)
Now the config file is ready!
###3. Enable acpi_fancontrol
We need to enable
acpi_fancontrol on kernel module options! Add this line to
options thinkpad_acpi fan_control=1
Activate kernel settings by running this:
sudo modprobe -r thinkpad_acpi && sudo modprobe thinkpad_acpi
In order to start the service any time you boot up your machine, we need to enable it!
sudo systemctl enable --now thinkfan.service
You can check if the service is running or not with this command:
sudo systemctl status thinkfan.service
I hope you find this tutorial useful! Have a nice day and hit me on Twitter.
