Poor Performance

You may also experience that your computer has difficulty carrying out simple activities, such as opening a new browser tab. Even simple tasks like typing or moving the mouse take longer than normal since Modern computers have thermal throttling technology that will slow the processing speeds of your computer to prevent damage to the internal components. Even though it seems like an overheat, the processor, motherboard, and/or graphics card are just at the thermal limit, often 80 to 90°C and The only real way to fully overheat and damage a modern computer’s hardware is to overclock and add more voltage than your cooling system can handle.

It is reasonable to expect that the computer will overheat in such a situation. The laptop is prone to overheating if you use it in an area with poor air circulation.

Another option is that the air exhaust vents on the laptop are clogged, which would restrict airflow and cause overheating problems. If the thermal paste on the CPU is no longer effective, improper thermal management may be the cause of overheating.

6 Ways To Prevent Overheating In Laptops

Overheating is a laptop killer. Here are the best guidelines for keeping your laptop cool and avoiding overheating.”

Clearing Air Vents And Fan

Removing dust from the laptop is very efficient for better and unclogged airflow Nowadays, CPU fans are typically found in laptops to ensure proper cooling. In comparison to gadgets like cell phones, a laptop is more likely to collect dust over time. The first thing you should check if your laptop is overheating is if there is a lot of dust gathered in the air vents or around the CPU and the entire cooling system.

You can clear your laptop’s vents at home by using a pressurized air spray and spraying directly at the vent, which is usually located at the side of the base of the laptop. You can do this method by shutting and unplugging your laptop from its charger and aiming the spray’s nozzle directly at the vent and giving a short burst of air. Another way of clearing debris out of air vents is to use a mini vacuum cleaner or a blow dryer; however, in most cases, it is better to seek out professional help.

Replace Cpu Thermal Paste

The CPU or GPU is connected to the metal sink via a thermal paste or pad, which conducts heat. The heat is then transferred from the processing unit to the cooling fan through the metal sink. If your thermal paste or pad degrades, it leads to problems of overheating, so it is recommended to check your CPU thermal paste and replace it if needed.

Use Orignal Charger

It is better that you use the laptop’s original charger. Third-party compatible chargers from different manufacturers may be widely available and far less expensive than the manufacturer’s charger. However, using a genuine or approved laptop charger is always preferable.

Use A Laptop Cooling Pad

Even though your laptop has an inbuilt fan to cool the CPU, purchasing an external cooling pad for it might help it stay cooler and assist your laptop in removing excess heat so that your laptop runs peacefully. However, you should be aware that each device has a different cooling system, so you must make sure the cooling pad you choose is suitable for your laptop.

Check For Viruses

The presence of viruses and malware on your laptop might cause it to work too hard and overheat. Choose Any reliable antivirus program that should be able to identify and get rid of any unwanted programs that are making your laptop work too hard.

Power Settings

Switch the power plan on your laptop from High Performance to Balanced or Power Saver. With this change, the system would not utilize its full CPU speed, just using what it needs to perform your programs.
