You can monitor your processor temperature using BIOS/UEFI or a hardware-monitoring application. For a quick baseline, restart your computer and enter BIOS or UEFI using a key such as F2 or Delete, then look under Hardware Monitor or PC Health. For temperatures while Windows is running, tools such as HWiNFO or Core Temp can show current and per-core readings. If you're wondering how to check CPU temperature, using a monitoring tool is usually more useful because you can observe temperatures during gaming, video editing, or other demanding tasks. Windows itself generally does not provide a built-in CPU temperature display.
