How To Know Your CPU Overheating? How to Fix It

Laptop and PC are essential for today’s life; whether you are a working person, student, or belong to any category, you can’t complete your daily tasks without a PC. CPU Overheating issue is faced by many of us. Overheating is such a disaster for any electrical device. But excessive heat is bad for your PC’s health. High temperatures can cause high damage to circuits and explosions.

Although PC and laptops have multiple fans that catch cold air inside and pull out the heat outside, these fans help manage the airflow of cold and hot air. When your computer is getting older, its heat drawing ability gets worst. Because many things affect the cooling systems, they cannot completely pull out the heat.

So it’s needed that time to know about the CPU overheating symptoms, consequences, and how to fix the CPU overheating. Let’s get started!

Why Is My CPU Overheating So Fast?

Why Is My CPU Overheating So Fast

Are you worried about CPU overheating laptop? One possible reason is you are using your computer or laptop for a long duration of hours? But some other reasons are mentioned below:

  • If your CPU vents are clogged, warm air gets trapped inside; it will cause the CPU overheating.
  • If your system has a lousy cooling system, it will also cause the CPU to overheat because it has built-in small fans that help the system circulate the air according to the CPU cooling needs.

How To Tell If PC Is Overheating? (CPU Overheating Symptoms)

I will tell you some symptoms you can match if you have more than one that will be alarming. These will help you how to know if CPU is overheating?

  • Abnormal fan sound.
  • Sudden shutdown and restart or automatically shut down.
  • Flickering, crashing, whole blue screen and hanging.
  • Feeling high temperature on everyday use or idle state.

What Is The Cause Of CPU Overheating?

CPU is designed to work in high temperatures, and it’s expected that the CPU is heated up and gets very warm. Two hundred degrees Fahrenheit is average, but if it exceeds that limit, it will cause severe problems for the PC. Have a look.

Electric Signal:

A computer CPU works depending on electric signals by passing them through a microscopic transistor or sometimes by blocking them. If electricity is blocked inside during passes through the CPU, it will produce heat.

Usually, the CPU gets hot while doing high-performance work or heavy use. That’s not a big deal if this not often happens because regular CPU overheating is mostly a sign of a damaged CPU and computer.

Heavy Load:

CPU temperature is directly proportional to the electricity amount that passes through it. If you are doing routine tasks like a spreadsheet, mailing and word processing, they are not that heavy, so the CPU is cool down quickly. But if you are using the computer for complicated tasks like the financial model, 3D modeling and walk-through architectural design.

Heavy third-party software is included in this list, like computer design software, because these tasks are computationally intensive. So they will cause the CPU to heat up and become more active. A good CPU runs at default factory settings that can manage the heat and cooling systems. So they are not overheating quickly, even in harsh and heavy loads. But if you are overclocking your CPU, it will make more heat.

Air Flows Issues:

The computer’s case and multiple cooling systems move the CPU heat outside. But if the cooling system is not configured or the air does not flow properly, it will cause the CPU overheating alert MSI.

It might be because of dust, so if you are dealing with this type of problem, you can use compressed air to blow out the case, inlet and exhaust ports. It might help to remove clogged dust from airflow passages.

CPU Cooler Failure

CPU Cooler Failure

Most CPUs are covered with a cooling assembly consisting of 3 components: a fan, heatsink and a thin layer of thermal paste. They will help transfer heat from the CPU to the heatsink and fan. If your CPU overheating temperature, not because of dust, so you need to check that fan is spinning and replaced. You can solve it by professionally reattaching the CPU cooler and by reapplying the thermal tape so you may get a fresh coating.

Cooling System Failure

Your CPU cooling system must at least have two fans. One is a case fan, and the other is a power supply fan. If any of these fans are not working, your CPU releases the hot air, but the exhausted, hot air gets blocked inside and creates trouble for the CPU and other components. This problem can solve by replacing the defensive fan.

How To Fix CPU Overheating?

I hope you will get the answer to your question about why my CPU is Overheating. Now, let’s move to the solution to this problem. You can follow any of them according to your need to improve the efficiency of the computer. Let’s look at CPU overheating on startup:

1) Checking The Thermal Paste Of Your System

You must check whether the thermal paste first works appropriately or not. Because sometimes, CPU overheating occurs when you are not changing your thermal paste. When it gets older, it might not be able to travel to the cooling fan, so you have to change it.

2) Avoid Overclocking

Overclocking is the term that refers to the process that speeds up the processor to run the computer fast. GPU and CPU are working fast, creating a lot of heat. So all you need to do is throttle back the overclock and cool down your CPU when doing overclocking.

3) Cleaning The Dust

Clean your computer is the basic rule to keep in good condition. To prevent overheating, you can clean your CPU, fans, and other relevant components inside your computer. Dust is like poison for computers and their components.

If the dust is settling down around the fan, it will cause the CPU to overheat. So clean the components, especially internal fans near the supply power, front and back of the case.

4) Upgrade CPU Fans

This solution represents an efficient way to solve your overheating problem and save your system. Upgrading the CPU fan not only leads you to fix the CPU overheating problem but also gives a longer lifespan to the components of the computer. That will also help for giving better-operating results.

5) Checking the Cooling System

You need to check out whether the cooling system works properly or not. Overheating is normal while doing simple tasks because when the CPU is processing, it will create hot air. But if the CPU Overheating while gaming and working regularly, it’s not good for the health of your computer.

When computer components produce heat while working, the cooling system will cool it down. If you are applying other methods above, like cleaning the system, but it still overheats, then you may concern about the cooling system functionality. You have to replace it with the new one to eliminate CPU overheating.

CPU Overheating In BIOS

CPU Overheating In BIOS

If you are concerned about how hot the should CPU is in BIOS? Then I will give you the answer; the first thing you have to do is make sure that the BIOS temperature must be in an acceptable condition.

Your CPU must be at 30 to 50 degrees Celsius, but if it’s heating above 80 Celsius, your pc gets hotter, and CPU overheating is happening. AMD processors overheating might have a 60 Celsius limit of maximum temperature in BIOS. So AMD CPU overheating varies from model to model or according to the situation.


Can Overheating Permanently Damage A CPU?

Yes, it is possible; it might damage the CPU when overheating occurs. Thermal shutdown is causing the CPU shutdown before any real or permanent damage. If the damage happens to the system because of overheating, it will never affect the life of the CPU. But if it’s happening multiple times, it will permanently damage your CPU.

Can Damaged CPU Do Their Work?

If you use an installed CPU, it will not work even its one socket is damaged. But the motherboard CPU can work if the socket is damaged. Because in this type of situation, your motherboard is on and acts like handling processing, but it might have some issues.

How Do You Clean Thermal Paste?

You can use isopropyl alcohol to clean the thermal paste. Wipe it gently on the surface and wipe in straight lines. Repeat the process until you get the thermal paste removed. Remember that the thermal compound maintains its efficiency in the same way.

Are 80 Degrees Celsius Hot For A CPU While Gaming?

If you are around 70 to 80 Celsius degree, it’s considered normal while gaming, but it’s a little bit safe, not wholly. Because it’s close to dangerous levels of CPU Overheating, suppose you have reached 90 degrees Celsius while gaming; your CPU is damaged in that case.

What Happens If CPU Overheats?

The computer or laptop is crashed due to overheating. You may find blue screens, sudden shutdown, and the computer not properly working.
