Core Temp is a free utility software that monitors your computer’s central processor’s (CPU) temperature. It displays the temperature of individual cores in real-time so you can see any temperature fluctuations and includes basic information about your processors such as model and platform. It’s a great tool if you overclock your processor or think it may be overheating.
Core Temp isn’t the only lightweight Windows application you can download to measure and display your core temperatures. Real Temp and HWMonitor are similar programs that offer many of the same features as Core Temp, such as setting an alarm to alert you if your processor temperature spikes too high. What sets Core Temp apart is the ability to add plug-ins, increasing its number of features and overall functionality.
