What is Thermal Throttling and How to Prevent It in 2023?
Imagine you’re running a marathon on a scorching summer day. If your body gets too hot, you’ll naturally start to slow down to avoid overheating.
The same principle applies to the microprocessors in your computer. This process of slowing down to prevent damage from overheating is known as thermal throttling.
In this article, we’ll explore what thermal throttling is, why it happens, how it impacts your computer’s performance, and most importantly, how to prevent it.
The Short Answer to “What is Thermal Throttling and How to Prevent It”
Thermal throttling is a safety measure in computer architecture that automatically lowers the performance of a CPU or GPU when it gets too hot. This reduction in performance, termed ‘throttling’, lowers clock speeds, thus decreasing heat generation. This may result in a slower user interface on desktops or reduced frame rates in games. Essentially, when the heat emission from a GPU surpasses what its cooling system can manage, its core and memory frequencies are reduced. In simpler terms, thermal throttling is like a computer’s way of ‘cutting’ power to maintain safe temperatures and prevent overheating.
Understanding Thermal Throttle
To ensure your system runs smoothly, the CPU or GPU— your computer’s brain— automatically adjusts its frequency based on the actual needs.
This adjustment, or “throttling,” aims to conserve power and reduce the amount of heat generated by the chip. It’s a power management technique that kicks in when these components reach temperatures that could potentially harm your hardware.
Purpose of Thermal Throttling
The main goal of thermal throttling is to cool down the CPU or GPU so that it doesn’t exceed a certain temperature threshold. This is achieved by lowering the core clock speed of the processor.
As a result, the device draws less power and generates less heat. It’s like taking a break during a strenuous workout – you lower your activity level to cool down and prevent overheating.
Protection Offered by Thermal Throttling
Think of thermal throttling as a built-in safety feature in your computer’s hardware. It’s like a guardian angel that steps in to save the day before your system reaches dangerous heat levels.
It ensures that your precious components don’t overheat to the point of becoming unusable.

Impacts of Thermal Throttling
While thermal throttling serves as a guardian angel for your computer hardware, it’s not without its downside.
Performance Impact
When thermal throttling steps in to cool things down, your CPU or GPU’s clock speeds are reduced, leading to slower operation. Think of it like trying to run in slow motion.
You’re still moving, but not as fast as you’d like to be.
Game Lag Due to Thermal Throttling
For gamers, this slow-motion effect could mean the difference between victory and defeat. As the clock speed drops, so do frame rates in games, leading to game lag.
That perfect headshot you were aiming for in your favourite game might just miss because of a sudden lag!

Signs of Thermal Throttling
Recognising the signs of thermal throttling can help you act swiftly and take necessary preventive measures.
Beyond just reduced performance, there are several symptoms that could hint at thermal throttling:
- Unexpected Slowness: If your computer is performing slower than usual, especially during heavy tasks like gaming or video editing, it could be a sign of thermal throttling.
- Frequent Crashes or Shutdowns: Computers are designed to shut down automatically if the temperature reaches a critically high point. If your computer crashes or shuts down frequently, particularly during heavy workloads, it might be experiencing thermal throttling.
- Overheated Surface: If your computer’s surface is too hot to touch, it’s a clear sign that the internal components are overheating.
- Fan Noise: The fan in your computer works harder to cool down the system when it’s overheating. So, if your fan is making more noise than usual, it could indicate that your system is struggling with high temperatures and potentially thermal throttling.
Remember, if you observe these signs, it’s crucial to check your system temperatures and cooling solution to prevent potential damage.
Preventing Thermal Throttling
Now that we know the what, why, and how of thermal throttling, let’s delve into the most important part – how to prevent it.
Importance of Adequate Cooling
Firstly, adequate cooling is crucial to prevent thermal throttling. Think of your computer as a car. Without a proper cooling system, your car’s engine would overheat and break down.
Similarly, your computer needs a good cooling system to dissipate heat and keep temperatures in check. This can be achieved through proper airflow in the PC case, using efficient cooling solutions like fans or liquid cooling, and keeping the system free from dust and debris that can obstruct airflow.
Thermal Threshold and Workload Management
Another preventative measure is understanding the thermal threshold of your CPU or GPU and managing the workload accordingly. When your GPU takes on a heavy workload, like gaming, it generates a lot of heat.
If your cooling solution can’t dissipate heat quickly enough, the graphics card starts to drop performance to shed heat.
The core and memory frequencies start to drop—along with your framerates—until temperatures drop to a safe operating range. Knowing when to take a break can save your system from constantly hitting the thermal threshold and throttling.
Monitoring System Temperatures and Detecting Throttling
To effectively prevent thermal throttling, one needs to be aware of the signs and be able to detect when it happens. Constantly monitoring your system’s temperatures can help identify if your CPU or GPU is consistently hitting high temperatures, which could indicate thermal throttling.
Various software options allow you to monitor these temperatures in real time, such as HWMonitor, Core Temp, or SpeedFan. Using these tools, you can keep an eye on your hardware and ensure it’s not frequently overheating.
If you notice consistently high temperatures, it might be time to check your cooling system or consider giving your system a break to prevent hitting the thermal threshold.
Remember, staying informed about your system’s performance and temperature patterns is the first step in preventing potential damage and optimising performance.
Conclusion
Thermal throttling is a necessary function to protect your computer’s vital components from overheating and potential damage. However, consistent thermal throttling may indicate an issue with your cooling system that needs to be addressed.
With an understanding of thermal throttling and its prevention, you can optimise your computer’s performance and prolong the lifespan of its hardware components.
Remember, just like you need to hydrate and cool down during a strenuous workout, your computer needs to stay cool under heavy workloads too!
FAQs
What happens if thermal throttling is ignored for a prolonged period?
Ignoring thermal throttling over a long period can lead to irreversible damage to your CPU or GPU. Prolonged overheating can cause the silicon and other materials in your chips to degrade faster, reducing the lifespan of your hardware. In extreme cases, it can lead to hardware failure, which could mean expensive repairs or even the need for a complete system replacement.
How does ambient temperature affect thermal throttling?
Ambient temperature can significantly impact the efficiency of your cooling solutions and hence contribute to thermal throttling. If you’re operating your system in a hot environment, it becomes more challenging for the cooling system to dissipate the heat, leading to increased temperatures of the internal components and potentially triggering thermal throttling. Ensuring your computer operates in a cool environment can help prevent thermal throttling.
Does the choice of computer case affect thermal throttling?
Yes, the choice of a computer case can indeed affect thermal throttling. Cases with good ventilation allow for efficient airflow, which aids in cooling. The inclusion of additional fans or openings can also help. On the other hand, a case with poor ventilation could trap heat inside, making it difficult to maintain a cool temperature, thereby increasing the likelihood of thermal throttling.
