What Does Heat Do to a Laptop’s CPU? (3 Things)
Understanding why the temperature of your computer’s CPU matters is crucial to maintaining its optimal performance. While it may seem obvious that high temperatures can negatively impact electronic devices, it’s important to know precisely how a processor is affected by heat.
To begin with, it’s worth noting that processors are constructed using conductive and semi-conductive materials, which means they can withstand high temperatures without suffering any damage. However, despite their robust build, CPUs are still vulnerable to two primary issues caused by excessive heat: thermal expansion and resistivity.
Thermal expansion occurs when the heat causes the components of the CPU to expand, which can result in physical damage to the processor. On the other hand, resistivity is the tendency of the processor to resist electrical currents as its temperature increases, leading to performance degradation and potential hardware failure.
To avoid these problems, it’s essential to monitor the temperature of your CPU and take the necessary steps to prevent it from overheating. This includes optimizing your computer’s workload, ensuring proper ventilation, and maintaining your device’s cooling system. By taking these measures, you can keep your CPU running smoothly and extend the lifespan of your device.
#1 Thermal Expansion
Thermal expansion is a natural occurrence that happens to every substance, including computer chips. When a laptop’s CPU operates at 90 degrees Celsius or 90 C, thermal expansion occurs within the chip. Essentially, thermal expansion means that the chip’s components expand as they heat up, and then contract as they cool down. This is a constant process that happens every time the laptop is turned on and used.
However, the issue arises when the thermal expansion causes the components to expand beyond their limits, leading to damage or failure of the chip. The tiny connections within the chip can become distorted or broken due to the excessive heat, leading to errors, glitches, or complete failure of the chip. This is why it is crucial to keep the CPU temperature at a safe level, ideally below 90 degrees C, to prevent thermal expansion from causing irreversible damage.
When a laptop’s CPU heats up, it affects not only the thermal expansion but also the resistivity of the materials used to make it. Resistivity is a measure of how much a material resists the flow of electricity. As the temperature of the CPU increases, the resistivity of the materials used to make it also increases. This can cause the CPU to become less efficient in processing data and can lead to other issues like crashes, freezes, and even permanent damage.
So, is 80 degrees Celsius hot for a CPU? It’s certainly getting up there. Most CPUs are designed to operate at maximum temperatures of around 70-80 degrees Celsius, so if your CPU is consistently running at or above these temperatures, it’s a sign that something is wrong. It could be that the cooling system in your laptop is not functioning properly, or that the thermal paste between the CPU and heatsink needs to be reapplied. In any case, it’s important to address the issue before it causes more serious problems for your laptop’s CPU.
#3 Overheating Failsafes
Overheating is a common problem faced by laptop users, and the CPU is the component most affected by it. In fact, overheating can cause serious damage to the CPU, potentially rendering the entire laptop useless. This is why many laptops are equipped with failsafes that kick in when the CPU temperature reaches a certain threshold.
One such failsafe is called thermal throttling, which is a process in which the CPU automatically reduces its clock speed to generate less heat. This can cause a noticeable drop in performance, but it’s better than risking damage to the CPU. Another failsafe is simply shutting down the laptop altogether when the temperature gets too high.
These failsafes are essential for protecting the CPU from the harmful effects of overheating. Despite the existence of failsafes, they cannot guarantee complete protection against overheating, and there are still potential risks. For instance, using a laptop in a hot environment may cause the CPU to overheat, even with failsafes in place. It’s important to be mindful of the temperature of your laptop and take steps to prevent overheating.
One way to prevent overheating is to ensure that the laptop’s cooling system is working properly. This can be achieved by regularly cleaning the laptop’s vents and fans to remove any dust or debris that may be blocking airflow. Additionally, using a laptop cooling pad or elevating the laptop to improve airflow can also help to prevent overheating.
In conclusion, overheating can cause serious damage to a laptop’s CPU, but failsafes such as thermal throttling and automatic shutdown can help to protect it. However, these failsafes are not foolproof, and it’s important to take steps to prevent overheating in the first place.

In general, CPU activity is the primary culprit behind a hot computer. This activity generates heat through electrical resistance, which we will discuss in more detail shortly. The more you use your CPU, the hotter it gets, so reducing your computer’s workload is the best way to keep temperatures under control.
If your computer is prone to operating at high temperatures, it’s important to consider environmental factors that may be exacerbating the issue. We will cover these factors in greater detail later on. By managing both CPU activity and environmental factors, you can help keep your computer running smoothly and prevent overheating issues.
#1 Electrical Resistance
Electrical resistance is one of the primary reasons why a computer’s CPU heats up. When an electrical current flows through a material, it encounters resistance, which converts electrical energy into heat. This heat can accumulate and cause the CPU to overheat if not properly managed.
Several factors influence the electrical resistance, including the thickness and length of the conducting material, as well as the temperature. As the temperature of the material increases, its resistance increases, leading to more heat generation. The resistance also increases with the length of the material, which is why longer wires generate more heat than shorter ones.
Another factor that influences electrical resistance is the quality of the material itself. High-quality materials such as gold and copper have lower resistance and generate less heat than lower-quality materials such as steel.
The design of the computer’s circuitry also plays a crucial role in determining the electrical resistance and heat generation. A poorly designed circuit with a lot of resistance can generate more heat than a well-designed one with lower resistance.
In summary, the electrical resistance of a computer’s CPU is a critical factor in determining its temperature. Factors such as the material quality, wire thickness and length, and circuit design can all impact the CPU’s resistance and heat generation. Proper management of these factors is essential to prevent overheating and maintain the CPU’s optimal temperature.
#2 Environmental Factors
Environmental factors can also play a role in making a computer’s CPU hot. One major factor is the surrounding temperature. If the room or environment is too warm, the computer will have a harder time dissipating the heat generated by the CPU. This can cause the temperature of the CPU to rise and result in overheating.
Dust and debris accumulating on the fans and heat sinks can affect the CPU temperature by preventing them from working efficiently. This can cause the CPU to heat up as the heat is not being dissipated properly. Additionally, placing a laptop on a soft surface like a bed or a couch can block the air vents and prevent the fans from working efficiently, leading to a rise in temperature and potential overheating.
Other environmental factors that can contribute to CPU overheating include exposure to direct sunlight, poor air circulation around the computer, and the use of high-performance applications that require a lot of processing power.
