If you want to test the thermal stability of your system you can perform a simple test, by running a cpu heavy application and then monitoring the graph. Efficient cooling matters a lot when it comes to cpu performance. If the cooling is made more powerful, the system can sustain high clock frequencies thereby delivering higher cpu performance. In the above graphs we can see that when the load touches peak levels, the clock and power consumption start throttling to bring the temperature down. Here is how it looks with all the graph plots. CPU Package Power - The total power consumption.Core Clocks - The overall Clock Frequency.In this example I shall plot the following metrics: Now right click any metric and click "Show Graph". It will open the "Sensors status" window. It shows a lot of details about the hardware as well as can plot graphs of dynamic metrics.Ĭlick Monitoring > Sensor status. The next tool that can show cpu temperature graphs is the commonly used Hwinfo. This is why it is recommended to have good cooling system, so that the cpu temperatures don't cross the limit to trigger throttling of clock frequency.įurthermore if under load the temperature peak levels are very high followed by very low clock frequency for throttling, this could indicate problems with the cooling system that need to be address immediately. However, as the temperatures touch peak, the clock frequency immediately throttles down to bring temperatures down to safe range, which causes the power consumption to come down as well As the load rises, the power consumption and temperature also rises. Note the correlation between the cpu metrics. In the screenshot, we can see that open hardware monitor is rendering the graphs for all cpu parameters in realtime, including Now on the left panel click in the checkbox for the metrics that you wish to monitor on the graph. The time is on the x axis and the duration length depicted can be adjusted. Plot Graph: Launch the application and click on View > Show Plot, and it will show graph plots on the right side. On my 5800H cpu it could not show metrics of the amd radeon integrated gpu. It works with both intel and amd cpus and on the gpu side supports nvidia very well. This includes cpu metrics, gpu metrics, memory usage and disk usage. Open Hardware Monitor is a free tool that can query a lot of different kind of sensors and fetch the information for user analysis. To stress the cpu I have used Cinebench, which causes the average load to go upto 100% and then we monitor various different graphs. Applications query these sensors through software functions and report the value to the user. The hardware components like cpu, gpu all have built-in sensors that track various parameters like temperature and power consumption. Along with the temperature, we can also plot other parameters like clock frequency, load and power consumption. In this article we take a quick look at some tools that can be used to plot a graph of the cpu temperature. This is often done to benchmark the efficiency of the cooling system and the thermal performance of the cpu. If you want to monitor the temperature of your cpu while running some intensive application you can plot the graph and see it in realtime.
