What is CPUTIN? [Answered in Detail]

A motherboard has different kinds of sensors.

So,  many hardware enthusiasts get confused when they encounter terms like CPUTIN. SYSTIN, AUXTIN, etc. These terms all are related to the temperature index of a CPU, but their exact meanings are different. 

In this blog, we will explain what these terms mean so continue reading if you want to know more.

What Is CPUTIN or CPU Temperature Index?

You need to know about your computer once you install a new motherboard on it. 

As we mentioned, a motherboard has different sensors; CPUTIN is one of them. It senses the temperature of the entire CPU. The CPUTIN value is displayed in a range with minimum and maximum values. 

The minimum value of CPUTIN is normally 40 degrees, while the maximum value is around 65 degrees Celsius. 

Since CPUTIN provides the temperature of the entire CPU, it is the best indicator of how hot your computer is getting. 

There are normally three things that most temperature readers display: Value, Min, and Max. 

Value refers to the current temperature value of the system. Min means the minimum value that the temperature reached recently, and max refers to the maximum value it reached.

In the case above, you can see all values are equal, meaning the CPU is not under much stress. It is idling. 

You should also be aware of other factors like thermal margin when it comes to CPU temperature. 

Where Can You Read or Find CPU Temperature Index Data?

There are multiple ways to get a CPUTIN reading, but the best way to do it is to use a tool called HWMonitor. Here’s how you can use the tool:

Step 1 – Go to the HWMonitor download page and download the setup file (according to your OS Type – 32-bit or 64-bit). 

Step 2 – You can now install the software by following the onscreen prompts. 

Step 3 – After you have installed it, you can run HWMonitor. You will see the following screen when you open the application : 

Step 4 –  You can now see the CPUTIN value. It doesn’t show in my case as I’m running this on a laptop CPU, but it should work if you have a desktop. 

Significances of CPUTIN Regarding Your PC Health

CPUTIN is very important data for the well-being of your PC. Here’s how a CPU Temperature Index can help you better your PC

CPUTIN shows you the current temperature of your CPU, which is always good to track. If your CPU temperature goes above a certain threshold, you can get them to the required level. 

With CPUTIN data, you know the most recent maximum and minimum value of your CPU temperature, and you can plan using your computer accordingly. You no longer have to take wild guesses. 

Proper CPU temperature data not only helps you maintain your CPU healthy, but can also show some underlying factors why your CPU is heating. 

For instance, In my case, the CPU doesn’t heat that much as I live in a particularly cold place so it idles around 25 degrees in the morning. I know my system temperature is in accordance with my environment temperature.

Such crucial data can help you out if you are a gamer as well; you know exactly the kind of cooling system you should use, the number of fans you should install, and the speed to run those fans. 

Is CPUTIN Different from AUXTIN?

CPUTIN is very different from AUXTIN. AUXTIN stands for Auxiliary Temperature Index, and it measures the temperature of your power supply. 

You might be wondering now how the power supply has different temperatures right? The thing is, a CPU power supply works with voltage. The more voltage you provide, the hotter it will get.

You might have noticed your laptop charger getting hot after you have charged your laptop for a while. The same principle applies to it. 

Is CPUTIN Different from SYSTIN?

CPUTIN is different from SYSTIN, which stands for System Temperature Index.

While CPUTIN shows the temperature of your CPU only, SYSTIN shows the average temperature of your entire system.

Since different components like SSD, RAM, GPU, etc., have their own temperatures, we need to average out all the temperatures if we want to know how hot our whole system is getting. 

Is CPUTIN Different from CoreTemp?

A CPU can have one more core; a core is basically the main processing unit of a CPU. The more cores you have, the more tasks you can perform on a computer. 

Anyway, CoreTemp is a CPU sensor that measures the core temperature of your CPU, but CPUTIN is a motherboard sensor that measures the entire CPU’s temperature.

So, CPUTIN might depend on CoreTemp, but CoreTemp doesn’t depend on CPUTIN. After all, its your core that gets hotter than your CPU!


What is Hwmonitor?

HWMonitor is a software from CPUID that provides you with various information about your computer hardware, such as the temperature its running at, the voltage it receives, the health of your battery, RAM, SSDs, etc. 

What is TCTL Sensor?

OS Kernels need a way to control temperature values. TCTL is one such sensor that can be used to control cooling systems in a CPU case. 

What is the ideal CPU temperature?

Normally, a temperature range between 40–65°C (or 104–149°F) is a safe bet.  This temperature is ideal for a normal workload, and if your CPU operates at this temperature, you shouldn’t worry. But when you are running graphics-intensive games, your CPU temperature can increase up to 80°C.  

Final Words 

We know CPU temperatures can seem very confusing, but you shouldn’t be too hard on yourself as it is confusing for everyone!

To recap,

  • CPUTIN is a motherboard sensor that measures your entire CPU’s temperature index (or range).
  • CoreTemp is a CPU sensor that measures the temperature of your Core.
  • AUXTIN (Auxiliary Temperature Index) measures the temperature of your power supply. 
  • SYSTIN measures the average temperature of your entire system.  

In conclusion, the thing that should actually matter to you is how you can keep your temperatures under a reasonable range so you can get the best out of your CPU.
