In my case sensor with index 8 is unavailable and sensor with index 4 always return 0, therefore I excluded them. thinkpad (#Chassis) – measures CPU, GPU and chassis temperature.Since there are sensors for every core, it feels redundant to use the package sensor as well, therefore we ignore it with this option: My ThinkPad P14s has 4 physical cores, therefore there are 5 sensors available: 1 sensor for the whole package + 1 sensor per core. coretemp (#CPU) – measures CPU temperature.Technically, thinkfan should support devices that can be removed/suspended, but there’s a bug preventing it from working properly in daemon mode. And this is what we’re using the sensor with index 1 for – to measure the GPU temperature. Instead such sensors show negative values here. tpacpi (#GPU) – this array of sensors represents pretty much the same temperatures as the one below (the chassis one), but with a little difference: the sensors are never missing here even if the device is offline (like GPU for example).A you can see, we have multiple hwmon entries having different names in the configuration file, here’s what they are: We use it to monitor CPU, SSD, WLAN and other devices’ temperature. hwmon – specifies a generic temperature sensor.Using nvml prevents the GPU from switching to suspend power state, causing battery drain and high temperatures. ‼️ IMPORTANT‼️: avoid using nvml option (temperatures read from proprietary nVidia GPU driver).
Sensors section of the configuration file describes all the thermal sensors thinkfan will use to keep an eye on the temperature. If you’re interested in what exactly all the above-mentioned configuration options do, welcome to this deep dive section. With this configuration the fan will be kept at a reasonably quiet level while still allowing you to use the ThinkPad on top of your laps.
