11 BEST CPU Temp Monitor Tools: PC Temperature Monitor 2021

Review of the Top CPU Temp Monitor Tools With Features, Pricing & Comparison to Select the Best Computer Temperature Monitor Software per your Requirements:

CPU Temperature Monitor is an application that will help you to check the CPU temperature by collecting the data from various sensors. In a complex technological environment, hardware resources are important, and monitoring them can give you continuous uptime, maintain peak-performance, and minimize the business risks.

Hardware Monitor provides the values of specific physical properties like temperature & voltage for physical components like CPU, battery, fans, motherboard, etc.

Top CPU Temp Monitor

Fact Check: Processors tend to endure high temperatures. New processors can bear up to 103 degrees Celsius without the CPU getting damaged. But the lifespan of other individual components can get shortened because of high temperature.

Puget Systems has done the testing and found that CPUs can adjust their frequency according to temperature and hence you don’t get the maximum performance. There can be very little performance difference between a CPU running at 30 degrees Celsius and 95 degrees Celsius.

The below graph shows you a CPU frequency based on cooling. For testing, it has used Intel Core i7 4790 and Gelid Silent Spirit Rev.2 CPU Cooler.

Pro Tip: If you have to use the CPU-intensive programs daily and this drives up your CPU temperature then you should use the tool that can regulate the fan speed. Also, check if the measures that are taken are adequate or not, else you can consider retrofitting a high-performance processor.

Who Needs CPU Temperature Monitoring

Gamers and Graphic Designers are high-performance users. They use to replace parts so that the PC would run fast. Gamers used to overclock the PC so that the online games will run smoothly but overclocking can increase the CPU temperature.

Reasons that can raise the CPU temperature:

There can be several reasons for the high temperature of CPU like dust, fan speed, or overclocking. Also, Malware attacks can make the CPU work harder and this will raise the CPU temperature.

Viruses (like system infectors, file infectors, & macros), Trojans (like Backdoor, Rootkit, etc.), and Worms (Email, Internet, Network) are the common types of malware infections that can make the CPU temperature rise.

Some programs have higher CPU requirements. Example, Video and Graphics editing programs, Games with high-resolution graphics, DVD burning programs, etc. Autostart programs can affect CPU usage. Sometimes browsers also use the CPU’s processing power as Plugins and add-ons run undetected in the background.

What Is Normal CPU Temperature

The CPU temperature should be 45 degrees to 50 degrees Celsius when it is idle. When you are playing a game, rendering a video, or doing some other intensive tasks then there will be a higher load and temperature could be around 70 to 80 degrees Celsius. CPU temperature between 80 to 100 degrees Celsius is the maximum. At this high temperature, the clock speed will reduce.

Measures to be taken if the CPU temperature is high:

Here is the list of measures that you can take if your CPU temperature is exceeding 80 degrees Celsius under load.

  • Check if the PC is clean and dust-free.
  • Check if the fan is spinning under the load.
  • Keep the computer in a cold environment.
  • Applying a thermal paste between CPU and CPU cooler. It is recommended to reapply the thermal paste after three years.
  • By stopping the overclocking. Overclocking means increasing the CPU’s clock/speed rate. It can be increased through BIOS settings. Overclocking increases the overall performance of your computer but it generates more CPU heat.

Why Is It Important To Monitor Computer Temperature?

The high temperature of the CPU can damage the motherboard or other devices. To avoid thermal damage, the CPU temperature should be monitored if you are using the CPU intensive programs. Also, monitoring the CPU temperature will help you to maintain peak performance.

Temperature is one of the major factors that can affect a server room. If the temperature is too high then the servers can get damaged. Overheating can cause permanent damage.

To ensure the overall reliability and uptime within the data center it is important to maintain the recommended environmental levels such as temperature, humidity, power, etc. So server rooms need to be monitored with internal as well as external sensors. Almost all the computers and processors contain integrated internal sensors.
