Lm-sensors (installed by default on Pop!_OS) is a text-based tool that runs in a Terminal.Intel OBL Distribution (Commercial Use) License This LIMITED DISTRIBUTION LICENSE AGREEMENT (“Agreement”) is a contract between You and Intel Corporation and its affiliates (“Intel”). The temperatures of your CPU cores and GPU card can be checked through software. Systems with dedicated GPUs tend to run hot under normal circumstances, so noticing an overheating problem can be challenging from ambient temperature alone. If your system is spontaneously shutting down, this may be caused by overheating. Typically, these thresholds are in the upper 80s or 90s Celsius, depending on hardware.

Modern hardware is designed to shut systems down when they reach temperatures that may be damaging to the internal components.

To investigate this, we'll use tools that can display CPU temperatures. If the CPU fan is spinning erratically, or you are experiencing random shutdowns, this may be the result of a thermal issue. NVMe drives can't be checked with a SMART Test through the Disks application but the package smartmontools can be used for this. Pay attention to the overall assessment, and to how close the values are working towards the failure point, which is typically 0. The terms "old-age" and "pre-fail" are normal. This test takes a few hours to run and will will give you a large amount of info about the health of the drive.Īll of the values start at 100, and work their way down to 0. To check the hard drive for disk failures, start the program Disks, select the hard drive on the left, then click the icon in the top right, and choose SMART Data and Self-Tests, and then click Start Self-test and choose the Extended test. If memory errors show up, the memory stick should be replaced. If any errors are found, please run it again in single core mode, and let it run overnight to check for any memory errors. Wait at least 20 minutes for the tests to run, or until any errors are shown in red. Right as memtest loads (blue screen), press F2 to enable multi-core mode. You would boot from a USB drive made with the ISO. Memtest86++ also has ISO downloads for personal use. While this will not put all of memory under test, it will make any memory error likely to cause instability if not part of the tested memory or show up clearly with errors in the memtester run
