Great for boiling water, it may not be the same for your computer components, so is 100ºC too hot for a GPU?

Yes, using your GPU (graphics processing unit) above 100 degrees Celsius is too hot and can damage the hardware. Most modern GPUs are designed to operate safely at temperatures up to 90°C.

Even though this is considered to be on the high side of their operating temperature range. Excessively high temperatures can lead to performance degradation, system instability, and even irreparable damage to the GPU.

High temperatures can cause “thermal throttling” (when your GPU automatically lowers its clock speed to prevent overheating) and therefore reduced performance.

In addition, extreme temperatures can make your GPU unstable and crash, potentially leading to data loss and other damage.

Using your GPU at temperatures of 100°C or higher for extended periods of time can result in permanent hardware damage. At these temperatures, the solder joints connecting it to the PCB (printed circuit board) can melt, leading to component failure and rendering your GPU useless.

The high GPU temperatures can have many causes. One of the most common causes is insufficient cooling, which can be caused by poor airflow in the case, insufficient or defective fans, or an improperly installed or defective heat sink.

Dust buildup and dirt buildup also hinder cooling, so it’s essential to clean your GPU and other components on a regular basis.

Other causes of high GPU temperatures include overclocking, which increases the clock speed and voltage of your GPU beyond factory settings, and running demanding games or applications that demand a lot from it.

So there are plenty of methods to lower GPU temperatures. These are essential to extending the life of your card and ensuring that you can continue to enjoy the performance above it.

Running your GPU at 100°C is too hot and can damage the hardware. To keep it running at its best, make sure you have proper cooling, avoid overclocking, and adjust settings where necessary to reduce the workload on your GPU. Doing so will ensure optimal performance and longevity of your GPU.
