The best feature of Core Temp is its reliability. Many OEM tools offer imprecise, latency-based readings from sensors outside the CPU itself. Core Temp reads directly from each core's temperature sensor, so spikes or drops in temperature are shown immediately. This rapid feedback allows you to identify issues with cooling, thermal paste failure, or poor airflow immediately. · Core Temp is a must-have for overclockers, as well as new system builders. Running a CPU hotter than specs will destabilize in a few degrees, so being able to track each core is key in knowing if one core is overheating v

Yes, Core Temp is fully free. Download it from the official site and install it without any limitations. There are no chargeable versions or subscriptions; plug-ins and mobile extensions are all open to all. The application is local and does not send your data anywhere. It's an uncommon tool that does what it says is what it does without expecting anything in return, but perhaps a polite update check.

Core Temp reads information directly from the DTS or Digital Thermal Sensor in each core, which allows for virtually no delays and very accurate readings.
