Unable to Set Max Temperature Using lm\_sensors: Solution
In this article, we will discuss how to solve the issue of being unable to set the maximum temperature using lm\_sensors. We will cover the key concepts related to this topic, including lm\_sensors, its configuration, and how to set the maximum temperature. The article will be divided into several subtitles, each focusing on a specific aspect of the topic.
What is lm\_sensors?
lm\_sensors is a free software tool for Linux that allows users to monitor and control various sensors in their computer. It supports a wide range of sensors, including temperature sensors, voltage sensors, and fan sensors. With lm\_sensors, users can monitor the current values of these sensors, set alarms for when certain thresholds are reached, and even control the speed of fans based on temperature readings.
Configuring lm\_sensors
Before you can use lm\_sensors to set the maximum temperature, you need to configure it properly. This involves loading the appropriate kernel modules and running the sensors-detect script to detect the sensors in your system. Once the sensors have been detected, you can use the sensors command to view the current readings.
Setting the Maximum Temperature
To set the maximum temperature using lm\_sensors, you need to edit the configuration file for the sensor you want to control. This file is usually located in the /etc/sensors.d/ directory and has a .conf extension. In this file, you can set the maximum temperature by adding a line like this:
set temp1_max 50This will set the maximum temperature for sensor 1 to 50 degrees Celsius. If the temperature goes above this threshold, lm\_sensors will trigger an alarm.
Troubleshooting: Unable to Set Max Temperature
If you are unable to set the maximum temperature using lm\_sensors, there are a few things you can try. First, make sure that you have the correct kernel modules loaded. You can check this by running the lsmod command and looking for the modules related to your sensors.
If the kernel modules are loaded, try running the sensors-detect script again to make sure that all sensors are detected. If sensors are still not detected, you may need to check your system's BIOS settings to make sure that the sensors are enabled.
If the sensors are detected and the kernel modules are loaded, but you are still unable to set the maximum temperature, try editing the configuration file manually. Make sure that the syntax is correct and that you are editing the correct file for your sensor.
Setting the maximum temperature using lm\_sensors is a useful way to control the temperature in your system and prevent overheating. By following the steps outlined in this article, you should be able to configure lm\_sensors properly and set the maximum temperature for your sensors.
