Why is My CPU So Hot: Full Guide In 2023

Computer processors are designed to make substantial temperature changes, and it is not uncommon for a CPU to get very hot and for its temperature to rise beyond 200 degrees Fahrenheit. Temperatures of over 200 degrees Fahrenheit are often acceptable. A processing unit’s purpose is to allow electrical signals to pass through its microscopic transistors or prevent them from passing through.

As electricity flows through the processor or gets stuck, it becomes thermal energy. While a high-performance box may have an extra processor that runs hot due to heavy use, a hot processor in a regular computer or system overheats is always an indication of a problem in the system.

How to cool down your CPU

How to cool down your CPU

The best way to cool off your computer is to find out who’s causing the overheating on your laptop. Once you’ve found why your computer is overheating, you’ll be able to resolve the problem, be it doing anything such as cleaning your computer, adjusting airflow, or closing some tabs.

CPU Heat

Under 60°CGood
60-70°CRunning okay
70-80°CMaybe okay if you’re overclocking
80-90°CNot good.
Over 90°CWarning!

Clean your PC

Cleaning your computer is as simple as removing and blowing out the dust and dirt that collect inside. Keeping your device dust-free and clean for at least half a year will ensure your PC operates correctly.
A cleansing both improves the efficiency and ventilation of your pc. Just cleaning your PC can significantly enhance its efficiency and ventilation. If you haven’t cleaned your pc in at least six months, this suggests that it’s due for deep cleaning.

Improve airflow

Your machine’s air vents will help prevent overheating by moving cooler air through your equipment. It might block its air vents if you use your laptop on a bed or couch. Use a table or laptop computer; cool air will pass through the ducts without incident.

Desktop computers need to be on a stable, firm surface in an accessible (i.e., far from a cabinet or close to the ground) location. Rather than placing it on a shelf or a carpet, position it on a rigid, flat surface with plenty of open space around it.

Check the fans

If you’re waiting for your PC to quiet down, the fans can’t be the obstacle. But if your PC is very hot and fans aren’t working correctly or are producing too much noise, it may be that the components are occupied or running incorrectly. Try cleaning your PC, creating more airflow, or replacing the fans.

Reapply thermal paste

Replace the thermal paste

Thermal paste, or heat sink compound, is a dense material applied between the heat sink and the CPU to improve heat dissipation. Thermal paste can become dry and hardened over time, which can affect your system’s cooling performance. If you are experiencing poor system cooling performance, it may be time to reapply thermal paste.

Stop overclocking

Overclocking is a way to make a computer’s microprocessor or graphics card perform physical actions that are finished per second. Of course, a higher clock speed will increase the temperature of a particular component. If your CPU is causing overheating when you overclock it too much, you may need to slow it down and repeat that process often.

Make sure your computer is in a well-ventilated area.

Computers produce a lot of heat and must be in a well-ventilated area to prevent overheating. If your computer is in an enclosed space, like a desk, the heat will build up and can cause damage to the laptop or even a fire. Make sure there is plenty of air circulation around your computer.
