Best CPU Temperature Monitors

All PCs and servers in a network generate some heat. There should be no issue if the heat is around the average level. However, a computer processor is built from several components: CPU, GPU, motherboard, fans, etc. If the heating is continuous and higher than usual, it can become problematic and damage these components. The best way to control the damage is to monitor the temperature of the CPU. So, If you notice a higher than normal temperature, you can try some fixes to bring the temperature lower. This can be done by using CPU temperature monitors.

Here is our list of the best CPU Temperature Monitors:

  1. SolarWinds CPU Monitor – FREE TRIAL Tracks and graphs the load for devices in a network. It provides real-time data of critical performance metrics like uptime, errors, and CPU response time.
  2. HWMonitor A complete hardware monitor. It can read voltages, temperatures, and fans sensors of a system.
  3. CoreTemp Monitors CPU temperature in a very easy-to-use manner. It displays the temperature of every core of each processor in a system giving you accurate CPU cores.
  4. Open Hardware Monitor A free, open-source hardware monitoring software. You can monitor all sorts of different components of your system.
  5. AIDA64 Extreme Monitors sensors of processors in real-time to collect CPU temperature, voltage, and fan speed readings.
