What are the Ways to Minimize GPU and CPU Temperatures?

Outside of implementing a high-performance CPU cooler, there are a number of other methods in reducing temperatures of your GPU and CPU if they are abnormally high. We’ll touch on a few of the methods for each below:

Lowering Your GPU Temperatures

Changing Your Thermal Paste

A simple technique, removing the heatsink between your GPU and replacing the thermal paste can be a great first step in minimizing excess heat. This is especially important for older computers, as the quality of the paste can be compromised after extended periods of time.

Cleaning the GPU Fans

Just as with the fans on your case or on your CPU cooler, the fans on your GPU are an important aspect in keeping temperatures low. The build-up of dust or debris on the fans themselves can slow their speed and effectiveness. Removing this dust with a duster or computer safe cleaning tool can pay dividends with their efficiency in lowering temperatures.

Minimize Overclocking

Although overclocking your graphics card is the dream scenario for performance, even the best GPU for Ryzen 3 3300x has a clock speed threshold before it starts producing excessive heat. If you have overclocked your GPU, consider dialing it back or removing it if you are experiencing excessive temperatures. While you may take a hit on your in-game visuals, your games will run smoother and cooler over the long run.

Replace Faulty Fans or Use Third-Party GPU Cooler

While seemingly obvious, always ensure that your GPU fans are functioning properly while in use. If one of your fans isn’t functioning properly, this will dramatically increase overall GPU temperatures. On a similar note, if you feel as though the stock fans on your GPU aren’t quite stacking up, you may be able to find third-party GPU coolers that can provide higher-performing fans for cooling.

Ensure You Have the Proper Drivers

In the event none of the above can get you within acceptable temperatures, always double-check to make sure your drivers are up-to-date. These are oftentimes found at the manufacturer’s website, although a quick web search can easily point you in the right direction.

On the contrary, sometimes a driver update can prove to hold you back and increase overall temperatures. In this case, downgrading to an older version of a driver can sometimes prove to help any issues, although your mileage may vary depending on your device.

Increasing Case Airflow

The overall airflow into your PC may be the root of higher temperatures, regardless of how well your GPU is functioning. If you have a small or low-profile case, you may have limited airflow in comparison to a pc case with a good airflow. Always make sure you have sufficient fans and proper airflow around your PC, especially if you are in a warmer climate or room. This also means you shouldn’t overcrowd your PC case with other devices or objects, as this will not only impede airflow but introduce heat from external sources.

Lowering CPU Temperatures

Using a More Powerful CPU Cooler

The most obvious and effective method in reducing CPU temperatures, purchasing a high-performance CPU cooler will be your go-to first step. As with the above-mentioned coolers, there are a number of options for fan size and compatibility. And although your CPU may have come with a stock cooler, they can oftentimes fall short when it comes to proper cooling, especially on overclocked PC builds.

Organizing and Cleaning Your PC

As with the GPU, allowing for better overall airflow throughout your PC case will ensure lower temperatures during demanding processes or gaming. Aside from the case and fans we mentioned above, properly organizing and cable-managing your build will allow for better airflow throughout your components. Cluttered cables and tightly packed cards or drives will greatly inhibit your PC’s ability to cool.

Additionally, dusty and debris-filled components will also act to increase temperatures. Keeping everything neat and tidy on the inside of your case can go a long way in not only cooling your PC but preserving its health and longevity.

Reapplying Thermal Paste

As with the GPU, the CPU can also see increased performance with reapplied thermal paste. Although many will apply thermal paste only when you initially install your CPU and cooler, it can potentially dry out and become ineffective. This is a simple and inexpensive step when trying to diagnose excessive CPU temperatures, so don’t shy away from cleaning off the old paste and reapplying.

Minimize Overclocking

Similar to the GPU, CPU overclocking can be a source of excess heat. While overclocking for increased gaming performance may be tempting, some processors may falter under the enhanced load. By either reducing the amount you are overclocking or by returning to the base speeds altogether, you can see more comfortable temperatures for your CPU.

Programs that Help Manage Your GPU Temperatures

After making all of the physical changes to help minimize GPU temperatures, there are a few final settings you can control to keep your temperatures low while gaming under more intensive conditions. Whether you want to change the overclocking, ramp up fan speeds, or simply monitor how your card is performing, there are programs available to help you keep these variables in check.

MSI Afterburner is one of the most popular controllers currently available. It allows you to create profiles for fan speeds, gives you a break down of your device and its current temperature and speeds, as well as allowing for benchmarking. Covering a wide variety of graphic cards regardless of manufacturer, this is a free and multifunctional program for anyone looking to monitor and control the settings for their GPU.

Whether you are looking to overclock your GPU or simply change your fan speeds, having full control over these variables can greatly improve the overall performance of your PC and its cooling.
