Why A Laptop Is Heating Too Much

It is important to know why a laptop is heating too much. Don’t ignore it if your laptop has recently been growing heated and slower than normal.

Your laptop seems to be overheating. If you don’t address it right away, you risk serious hardware failure and putting your data at risk. In the best-case scenario, you’re resigning yourself to a long-term annoyance that impedes your work and irritates you every time you switch on your computer.

How to Tell If Your Laptop Is Too Hot

Why A Laptop Is Heating Too Much

You’ll notice when your laptop begins to overheat. It will be blowing heated air about and will feel hot to the touch, moving from gently warming your legs to making you feel like you’re being branded.

Internal Temperature Goes Up

The laptop’s CPU temperature should be about 40-50°C (100-120°F) if you’re not doing much more than using a word processor or viewing a YouTube video in your browser. If you’re gaming or running many apps at once, a temperature of 60-70°C (140-160°F) is okay.

It’s time to be concerned when the temperature increases over 80°C (175°F). If you’re noticing temps like this, particularly when you’re not using your laptop much, you should investigate how effectively your cooling system is operating.

Performance Slows Down

Another symptom of your laptop overheating is a significant decline in performance. A heated laptop will perform as if it were dated 2006. Your applications and apps are slowing down. It takes longer for browser windows to load. Even simple tasks like typing or moving the mouse cursor take longer than normal.

Self-preservation is the driving force behind this. The laptop is reducing the performance of its hardware to reduce its temperature to a safe level. If it ran rampant and the temperature continued to rise, the hardware would be exposed to long-term harm.

The Fan Gets Louder

It’s almost comical that, as the laptop is slowly laboring to do simple chores, it begins to scream like an Airbus A380 racing down the runway. That’s because the laptop’s hardware asks the system fans to spin faster and more often to remove excess heat.

A computer may, of course, overheat silently. Some laptops don’t have fans at all, and fan failure is a common cause of overheating for those who do. Even if your laptop is growing substantially hotter, you will not hear the fan in this instance.

The Laptop Turns Off Without Warning

Most people think of this when you tell someone your laptop is overheating. The computer suddenly responds as though the battery has been taken out. You’re doing something essential one second, and then you’re yelling at a dark screen.

This occurs because the laptop’s performance degrades: most laptops have inbuilt heat warning systems that activate when the machine becomes too hot. If a heat threshold is surpassed to protect internal components, it will turn off automatically.

Excessive Dirt Buildup

Restricted ventilation is one of the primary causes of laptop overheating. Things start to heat up if the fan can’t adequately suck in cooler air and push out the heated air.

Excessive dirt and dust accumulation is by far the most common cause of airflow issues and, as a result, overheating. While the fan draws in the air throughout the day, it draws in dust, lint, skin cells, crumbs, hair, and who knows what else. It accumulates around the vents over time, obstructing airflow.

Broken Fan

A faulty fan implies your machine’s internals aren’t getting enough air to cool down. Because fans are one of the primary cooling systems in most laptops, they will overheat at some time.

You should be able to hear your laptop’s fan whirling in the background if you listen carefully in a calm area. If it isn’t, your fan may be broken.

The fan may be switched off or slowed down using the function keys on certain laptops, such as ASUS ROG or TUF models (F1 to F12). Look for a fan symbol on one of the keys to figure out which one it is. Try turning on and off this function on your laptop. Unintentionally, the fan has been switched off on occasion.

It’s conceivable that your laptop doesn’t have a fan, as previously said. They aren’t used on smaller computers like the MacBook Air, several ultrabooks, and most Chromebooks. A simple Google search of the model name and number should reveal whether or not a lack of fan noise is normal.

Other Hardware Problems

A hardware issue may also cause overheating. This may spin out of control since heat can harm hardware, and hardware damage can produce heat!

Let’s begin with the battery. A dead or damaged laptop battery may grow and bulge, creating more heat. If you observe a decrease in the amount of time you can spend away from a charger, and your laptop becomes hotter, replacing the battery is a good option.

Overheating may also be caused by dried-out thermal paste. Every CPU has a thermal paste layer between it and its heatsink to keep it cool. That paste might dry up over time and become less efficient in conducting heat. What’s the ultimate result? The CPU becomes hotter, increasing the danger of overheating.

Laptop components are quite delicate. They’re simple to take apart but very complicated to put back together. You open the case at your own risk since it’s simple to aggravate the situation and invalidate any warranties. Leave the repairs to the specialists unless you’re certain you know what you’re doing.

6 Effective tips to stop laptop Overheating

Check and clean the fans.

If your laptop starts to become hot, put your hand near the fan vents. If you see hot air coming out from the vents, the laptop’s fan is working properly. The fan may have gathered dust or broken down if there is little or no air. You may open up the machine and blast the dust out with compressed air. If the fan has stopped working, you should replace it. If you are unclear about how to open the laptop, you should get expert assistance.

Elevate your laptop

Inadequate airflow underneath the laptop might lead to overheating. This problem may be remedied by raising your computer and placing a small book behind it. Aside from utilizing a book, buying a laptop cooling pad will give enough standard airflow beneath your computer.

Use a lap desk

Using a lap desk is another way to ensure enough airflow. The little rubber feet on the bottom give normal elevation, which improves ventilation underneath your laptop. Some individuals, on the other hand, use computers on their laps. This reduces airflow underneath the laptop, resulting in overheating. A lap desk allows for continual ventilation, which keeps your laptop cool.

Controlling fan speed

Your laptop’s fans can’t operate at maximum speed because of constant airflow. When your fan spins at fast rates, your CPU is working hard and may get overheated.

Avoid using Intense processes.

Excessive operations in your laptop might cause it to overheat. By eliminating such operations on your laptop, you can keep it cool. For example, browsers that support video Flash put the CPU to work. The CPU will get hotter, and fan speeds will rise. As a result, it’s best to utilize a FlashBlock in your browser to ensure that flash videos are only activated when necessary.

Keep your laptop out of the heat.

Finally, excessive exposure to direct scorching sunshine, particularly during the summer, might cause your laptop to overheat. Due to hard drive expansion and battery damage, high temperatures may cause a computer to overheat. As a result, keep your laptop in the shade anytime the weather is hot. It’s best to have your laptop serviced as soon as possible if it’s shutting down and suffering major slowdowns due to overheating.


If your laptop overheats several times, it might result in major damage, leaving you with a dead computer and an expensive repair cost. Prevention is key, and a little goes a long way!
