Monitoring real-time CPU temperature is easy with small, fast monitoring software that isn't provided by the system itself. Apps like Core Temp and HWMonitor can retrieve temperature data instantly, showing current, minimum, and maximum temperatures. These temperature monitoring tools usually run silently in the background and may be configured to display your current CPU temperature in the system tray so you can see it right away. BIOS only offers a one-time view, so the readings from these programs help track performance over time. They are useful for catching a sudden high CPU temperature rise due to gaming, editing, or heavy work.
