They’re useful to keep open while gaming or doing other intensive tasks so you can check on your temps in real time and make any necessary adjustments.
Why GPU Junction Temperature Matters
GPUs are complex pieces of hardware that generate a lot of heat during intensive tasks like gaming or mining cryptocurrency. The GPU junction temperature refers to the hottest spot on the graphics card, usually directly under the GPU die. Keeping this temperature in check is important to prevent damage and ensure maximum performance.
When your GPU is working hard, the temperature can climb up to 95-105°C or higher. Anything over 100°C for extended periods of time can start to damage components and reduce the card’s lifespan. Thermal throttling may kick in, slowing down your GPU to prevent overheating and further damage. To avoid these issues, most graphics cards have built-in temperature sensors and fans to help regulate temperatures.
How to Monitor Your GPU Junction Temperature
To keep your graphics card healthy, you need to monitor its internal temperature. The GPU junction temperature refers to the hottest spot on your graphics card’s die. This temperature can often be 10-20°C higher than the overall GPU temperature, so it’s important to keep an eye on it.
Check Your GPU Software
The easiest way to view your GPU junction temp is through the software provided by your graphics card manufacturer. For NVIDIA cards, open the GeForce Experience app and click the “Performance” tab. This will show your GPU temperature, memory temperature, and junction temperature. AMD Radeon Software also provides temperature readings for your card.
Use a Third-Party Tool
If you prefer not to install extra software from NVIDIA or AMD, you can use a tool like GPU-Z, HWMonitor, or AIDA64. These free tools can provide a wealth of information about your graphics card, including current and maximum temperatures. Look for the reading labeled “GPU Junction” or “Hot Spot” to see your maximum GPU temp.
Aim For 90°C or Below
As a rule of thumb, you want your GPU junction temperature to stay below 90°C for optimal performance and stability. Anything above 95°C is in the danger zone and risks permanent damage to your graphics card. If your temps are running high, it’s a good idea to improve your case cooling by adding more fans or improving airflow. You can also undervolt your GPU to lower heat output, at the cost of a small performance decrease.

Take Action If Overheating
If your GPU junction temperature spikes above 100°C, take immediate action to prevent damage. Shut down any intensive 3D tasks you’re running and give your graphics card time to cool. Consider improving your case cooling, reapplying thermal paste to your GPU, or even temporarily underclocking your graphics card until you can diagnose and fix the issue. Prolonged overheating can degrade components and reduce the lifespan of your graphics card.
Monitoring your GPU junction temperature regularly and making sure it stays in a safe range is one of the best ways to keep your graphics card running well for years to come. Pay attention to the readings from your GPU software and take action quickly if temperatures start to climb too high. Your graphics card will thank you!
Tips to Keep Your GPU Junction Temperature in Check
Your GPU (graphics processing unit) junction temperature refers to the hottest spot on your graphics card. Keeping this temperature in a safe range is important to prevent damage and ensure optimal performance. Here are some tips to help manage your GPU junction temperature:
Increase fan speed
The fans on your graphics card work to cool the components and lower the overall temperature. You can use a tool like MSI Afterburner to manually increase your fan speed. Start with increments of 5-10% at a time and check your temperature to find the optimal speed. The higher the fan speed, the more noise it will produce, so find a balance that keeps temperatures in check without becoming too loud.
Improve case airflow
Make sure you have good airflow in your PC case. This means intake fans at the front pulling in cool air, and exhaust fans at the back pushing out hot air. Remove any unused expansion slots or drive bays that could disrupt airflow. Keep your cables tied back and out of the way. The more freely the air can flow over and around your graphics card, the better.
Undervolt your GPU
Undervolting your graphics card can lower power consumption and decrease temperatures. Use a tool like MSI Afterburner to slightly lower the voltage to your GPU core and memory in small increments. Check for stability with a graphics stress test after each change. When instability occurs, raise the voltage slightly back up. Even a small undervolt can provide noticeable temperature improvements.
Repaste your GPU
Over time, the thermal paste between your graphics card’s GPU and the heatsink can dry out and lose effectiveness. Replacing the paste with a high-quality thermal compound can help significantly lower temperatures. The process requires removing the heatsink, cleaning off the old paste from the GPU and heatsink, and applying the new paste. Be very careful to avoid damaging any of the components. For most users, repasting a graphics card is an advanced process best left to a professional.
By following these tips, you should be able to better manage your GPU junction temperature and ensure the longest lifespan possible for your graphics card.
