What is GPU & CPU thermal throttling?

Thermal Throttling Guide

The GPU & CPU thermal throttling happens when these components that are present inside your PC case become too hot. It could be because you are running a top-end game or working on a major software.

Naturally, these components tend to work slower to prevent themselves from getting heated up. When this occurs, your system’s performance reduces a bit and causes a decrease in the graphics card and CPU.

There can be a massive drop in the FPS of your GPU because of that. But you will want to know that it is required; otherwise, your PC device may get damaged permanently, as you read in the above paragraphs.

The process of GPU & CPU thermal throttling happens because of the overheating that has occurred inside your PC case.

Causes of thermal throttling

Thermal Throttling Guide

Due to poor ventilation

When you are working using a minimal PC case, then the ventilation inside there can be inadequate. It causes less space inside, and that brings about poor airflow inside. When you keep working for some time, then the heat increase causing thermal throttling.

If you notice, laptops have this issue because of the compact design. Besides, the dirt particles accumulating inside it cause a major hindrance to the airflow in there. So, if you are working using a small PC case, please update it with a larger unit.

Due to overclocking

The overclocking process frequently happens on your PC machine. When you want to overclock your PC often, you are pushing all the components to work harder beyond their capacity. When you do that, it causes heat to increase.

When you work for lengthy periods of time

When you are using an old PC and work for lengthy hours, then it may cause the CPU & GPU to become hotter quickly. In this case, there might be a massive buildup of dust and mold in there. You may want to get it cleaned so that the PC may run faster or get it upgraded.

GPU & CPU throttling and thermal throttling – The difference

Thermal Throttling Guide

Both GPU & CPU throttling and thermal throttling are not the same process. Though they signify that the GPU & CPU are running slow because they are hot, it is not completely accurate. The throttling is known as the DFS technology.

When under heavy load, the dynamic processor scaling technology is, also called as Dynamic Frequency Scaling (DFS), decreases the power consumption ability of the CPU. It is used by the processors for balancing the clock speed.

Besides, it also helps in the safe operation of the GPU & CPU and the power consumption. They help to keep your PC device running efficiently. The thermal throttling is the throttling that happens because of a low temperature.

The GPU & CPU functions effectively are done by reducing the frequency and the voltage avoiding a heat buildup.

How to know when your GPU & CPU is throttling?

Thermal Throttling Guide

You know that your GPU & CPU is throttling because it begins to work slowly and not very efficiently as before. Besides, it starts to hang randomly without any reason. You may want to check the PC case temperature.

If it is too hot, then you will want to shut it down for some time. You can also see the clock speed. When you see that clock speed is not stable and fluctuating, then it is a definite sign of your GPU & CPU throttling.

There are some basic hardware monitoring applications that are found on the Windows 10 and 11 operating systems. Here are the following steps that you would want to make use of so that it can work properly.

  • You can begin a normal application or task on your PC device.
  • Then press the Windows sign + R to start the command box.
  • In the text field area, you would want to type in perfmom.exe/res and use the enter button.
  • It launches the resource monitor.
  • Now, on the window, you can switch to the CPU tab.
  • Find the blue square indicating the maximum frequency.
  • When you notice a dip in the percentage, your GPU & CPU is throttling.

Apart from that, you may want to make use of a program like the CPU-Z for checking the throttling. The CPU-Z offers you with detailed information on the hardware of your PC device. When the throttling portion has a yes, then it is throttling indeed.
