How to Lower GPU Temperature? [Detailed Guide]

Getting a high temperature on GPU is quite normal as GPU works on heavy graphics and gaming stuff. But if the temperature gets too high, then it’s time to take some measures to lower it. But you don’t need to worry as we have here for you to help you out in lowering the GPU temperature.

Why a GPU gets Hot?

A GPU can overheat for a variety of reasons. If the vents on the back or sides of the card are blocked, this can cause heat to build up inside the case leading to higher temperatures. Poor airflow inside the case can also contribute to higher temperatures. If you have overclocked your GPU, this can also lead to overheating as the graphics card is pushed harder and produces more heat.

What Temperature is Too Hot for GPU?

So how hot is too hot for a GPU? On average, your GPU should stay under 80 degrees Celsius when gaming. If it exceeds that number, you might face some problems. For example, the fan might start spinning faster, or the screen might turn off.

There are a few things you can do to lower your GPU temperature. One is to make sure that nothing is blocking the airflow to your computer. Another is to use a software program to control the fan speed.

Is 85 Degrees Hot for GPU?

No, 85 degrees is not too hot for a GPU. In fact, it’s actually within the safe range. However, if you start to experience any issues, you should try to lower the temperature.

How to Lower the GPU Temperature?

Here are some tips that you can use to lower the GPU temperature on your own.

Cleaning the GPU

Dust is a killer when it comes to heat. If you have not cleaned your GPU in a while, now is the time to do so. You can use compressed air or a vacuum cleaner with a soft brush attachment to remove the dust from the fan blades and heatsink fins.

Here is how to remove the dust properly:

  1. Detach the case and check if there are traces of dust. Clean every particle of dust with a brush.
  2. Now detach the GPU and clean every side of it carefully
  3. Detach the fans and clean them properly
  4. Use a blower or cotton swap to clean the dust. The whole GPU body contains tiny holes, nooks, and crannies where dust can accumulate over time. Use a blower or cotton swap to dislodge and remove the dust from these areas.
  5. Remove the heatsink and check for dust buildup
  6. You might need to remove the heatsink in order to access the fan properly. If you do, check for any dust buildup on the fins and clean them off with a brush.
  7. Once you have cleaned all the dust, reassemble the GPU and put it back on your PC.

Applying Thermal Paste

When you detach the heatsink, you will also need to remove the old thermal paste from both the GPU and heatsink. Apply new thermal paste to both surfaces and then attach the heatsink back in place.
You can find thermal paste at any computer store or online.

Improving Airflow inside the Case

As we mentioned earlier, poor airflow inside the case can lead to higher temperatures. If you have a desktop PC, you can improve the airflow by adding additional fans. You can also use fan controllers to regulate the speed of the fans based on the temperature inside the case.

If you have a laptop, you might need to invest in a cooling pad that will help to dissipate the heat away from the laptop.

Replace the Thermal Paste

The thermal paste is used to fill the microscopic gaps between the heatsink and the CPU/GPU. Over time, the thermal paste dries out and becomes less effective. Replacing the thermal paste is a relatively easy process, and it can help to lower the temperatures.

Undervoltage the GPU

Undervolting is a process of reducing the voltage that is supplied to the CPU or GPU. This can lead to lower temperatures and can also help improve the component’s efficiency.

There are a few things to keep in mind when undervolting a GPU. First, you will need to find the safe voltage range for your particular GPU. Second, undervolting will lead to a lower clock speed, which can impact the performance of the GPU.

Monitor the Temperature

It is important to keep an eye on the temperatures of your CPU and GPU. You can use various tools to monitor the temperature, including built-in tools from AMD and NVIDIA.

There are also many third-party tools available. We recommend using one of these tools to help you keep an eye on the temperatures.

Disable Overclocking

Overclocking is one of the significant reasons that boost the heat in a GPU. So if you want to lower the temperature of a GPU, you will have to disable the overclocking. Many people do not know how to overclock their GPU, so it is a difficult task for them. The first step is to go into your computer’s BIOS and then look for the option to disable overclocking. If you cannot find that option, then you can try to reset the BIOS to default settings.


There are a few things that you can do to lower the temperature of your GPU. Improving the airflow inside the case, replacing the thermal paste, and undervolting the GPU can all help to lower the temperature. Additionally, it is important to keep an eye on the temperature and disable overclocking if you are not using it.
