How to Read CPU Temperature
Understanding CPU Temperature
CPU (Central Processing Unit) temperature is a crucial parameter to monitor, especially when it comes to the health and performance of your computer. High CPU temperatures can indicate overheating, throttling, or even damage to the CPU. In this article, we will guide you through the process of reading and interpreting CPU temperature.
Why Monitor CPU Temperature?
Before we dive into how to read CPU temperature, let’s understand why it’s essential to monitor it. High CPU temperatures can lead to decreased performance, power supply system throttling, and even damage to the CPU itself. In contrast, low CPU temperatures can be indifferent, but may also lead to increased performance.
Methods to Read CPU Temperature
There are several ways to read CPU temperature, including:
- Software monitoring: Using software like HWiNFO, GPU-Z, or AIDA64 to monitor CPU temperature.
- Hardware monitoring: Using hardware like the Intel HD UHD or AMD Radeon RX 580 thermal sensors.
- GPIO monitoring: Connecting a GPIO thermometer to the CPU’s GPIO pins.

How to Read CPU Temperature with Software Monitoring
To read CPU temperature with software monitoring, follow these steps:
- Install software monitoring software on your system (e.g., HWiNFO, GPU-Z, AIDA64).
- Launch the software and select "Thermal" or "System" as the core.
- Select the CPU from the list of available cores.
- The software will display the CPU temperature, which may be in Celsius or Fahrenheit.
- Take note of the current temperature and any anomalies or warnings.
