6. AIDA64 Extreme

All of the tools on this list are not free, and we lied to you about that. AIDA64 Extreme is premium software. However, it’s worth mentioning because of how versatile its feature set is. In addition, since we mentioned all the other free tools, we thought you might not mind us mentioning this one.

Windows, iOS, and Android support AIDA64 Extreme as a PC temp monitoring program. A new version of this program is among the best out there for finding out information about various computer components. The information displayed can be saved as CSV, HTML, or XML files.

AIDA64 Extreme has an extensive feature set, including hardware monitoring tools, benchmarking capabilities, stress testing techniques, diagnostics, and much more. There are plenty of free options out there if you only need a simple CPU temp monitor. AIDA64 Extreme comes with a hefty price tag if you only need the bare minimum.


  • It provides detailed information on programs installed, software licenses, etc.
  • Computer internals can be viewed in detail without opening the machine.
  • The application analyzes system RAM bandwidth while supporting multiple threads of memory and cache.

CPU Temperature Monitors FAQs

Why monitoring the processor for temperature is essential?

Keeping an eye on the temperature of the processor is crucial since it can affect the performance of your computer. The processor houses many computer parts, such as the motherboard and hard disk, and heat can damage these components.

How do you monitor the temperature of the CPU?

Tools that monitor CPU temperature give you precise information on sensors like temperature, fan speed, voltage and help you diagnose problems quickly.

What are the general features of CPU temperature monitoring tools?

Monitors that look at CPU temperatures have the following characteristics:

  • This allows for a high degree of customization.
  • It is possible to check CPU utilization and bandwidth.
  • Details about the hardware are provided.
  • The CPU temperature can be seen in real-time.

How do I check the temperature of the CPU?

The following steps will guide you through checking the CPU temperature on your PC or laptop:

Step 1) Download any of the software listed above.
Step 2) Install the software on your PC or laptop
Step 3) Run the software
Step 4) Check your processor temperatures on the software dashboard.

How do you reduce the temperature of the CPU?

The following steps will help you reduce the CPU temperature:

  • Do not place your computer near windows or vents.
  • Clean your computer’s fans
  • Remove any obstacles which prevent airflow from the computer.
  • Install a fan upgrade if the CPU’s stock fan is not working properly.
  • There may be space in your case to install additional cooling fans.
  • If you are gaming often or are using your PC intensively, consider liquid cooling or water cooling.
  • When overclocking your CPU, take extra precautions.

what is the idle CPU temperature?

When the computer is very active, the CPU temperature will range between 70 degrees Celsius and 80 degrees Celsius. A low temperature is normal when the CPU is idle. A high temperature means the processor isn’t really idle but is being overworked by background processes and services. A broken fan could be the reason for the high temperature if the CPU monitor indicates otherwise.

What CPU temperature is considered too high?

Many factors have to be taken into account when determining what an ‘acceptable’ CPU temperature is. However, generally speaking, Intel CPUs should remain below 40°C when idle, and beneath 85°C during full load.
