Is it necessary to monitor server CPU temperature, if it was working just fine for a long time, without any monitoring at all?

Is CPU temperature monitoring essential, even if the server has functioned flawlessly for an extended period without it? Q: Is it worthwhile to monitor my CPU temperature? A: Every CPU generates heat during operation. Put simply, the faster the CPU, the more cores it possesses, and so on, the greater the heat it produces while working. CPUs have a maximum operating temperature that they can withstand without damage. This upper limit is specific to each CPU model. Exposing a CPU to temperatures beyond this threshold can lead to various detrimental effects, including system resets, shortened lifespan, and even complete CPU failure. Keep in mind that the CPU’s heat also affects the motherboard it’s installed on – thermal damage can occur to both the motherboard and other connected components. Hardware components like CPU coolers are designed to prevent CPU overheating. Additionally, modern CPUs have integrated thermal sensors that can be accessed to determine the current CPU temperature and trigger necessary actions. Therefore, it’s crucial to be aware of the current CPU temperature and take steps if it’s excessively high. It might be time to upgrade the cooler or rearrange hardware components, but it’s always best to be informed of potential problems before they arise. To monitor CPU temperature, you can utilize free software like SpeedFan (Windows) or lm-sensors (Linux). In both cases, it’s possible to establish data sources (via WMI and/or SNMP) that provide the necessary data and monitor them using standard IPNetwork Monitor tools. If the motherboard manufacturer of your Windows target machine implements WMI in their drivers, you can retrieve the CPU temperature using WMI, as illustrated in the example below: Note: this value represents the temperature in tenths of degrees Kelvin. To convert to Celsius, subtract 2732 from the value and divide the result by 10, i.e., tempC = (value – 2732)/10; If the lm_sensors package is installed on a target UNIX-like system, you can create an SNMP Custom monitor using the following settings: Note: divide the resulting value by 1000.
