Have you ever think why computer experts always give importance in cooling? It is because some computer parts like the processor, the graphics card create heat especially when they are overclocked which is not good for their health (decreases lifespan).
But it is really very interesting why the processors get hot so much and how you can actually control the overheating problem of any processor in your PC? If you are also interested in PC hardware you should read this post because here I am gonna discuss four reasons which directly affects in CPU overheating, so let’s discuss-
Don’t worry I am not gonna explain the heating process of CPUs in technical terms, I shall just tell about it in general language so that everyone can understand.
Why processors (CPUs) get hot?
There are different reasons due to which a processor radiates heat, but if we distinguish it category wise, a processor gets hot because:
- The transistors.
- Poor cooling system
#1. CPU has to process commands:
When we give a command it directly goes to the CPU, then processed in the processor and finally, you can see the output in your monitor (the result of your command). This whole process is done in a fraction of seconds. And a CPU has to process multiple commands at the same time.
And when you overclock any processor, the clock speed increases and overall power consumption of CPU also increases. Of course, if the power consumption increases, the heat produced by it is also increases. So, ya, we can say that this is the main reason due to which a processor gets hot.
#2. The transistors:
The processors are made of transistors. No, I am not saying it is made of only transistors, but a CPU contains a couple of millions of transistors and interestingly they heat up after power consumption. The transistors uses binary digits, only 1 and 0.
Just think, what happens when you put together millions of transistors in a small area? It obviously gonna heat up when getting power. This is also a big reason due to which a processor heats up.
#3. Poor cooling system:
It is normal to see processors heating up to 40-50 degrees but if it goes beyond that, there must be some problems. A good cooling system plays a big role in the cooling of a computer. You have to give enough space so that the air can pass through it quickly, a good CPU cooler and fans too.
All of these together make a PC’s cooling system good and powerful. So, if you have a good cooling system, you don’t have to face CPU overheating problems. In general, CPU heats up but how much it can be controlled by a good cooling system easily. That’s why make sure to use a good cooling system.

Overall, a powerful cooling system is very important and without it a CPU can heat up at an extreme level.
It is obvious when you overclock any computer part, no matter whether it is GPU or CPU, it radiates extra heat. Well, a processor has to consume more power to deliver more frequency, output.
And when it consumes more power, the transistors, which I have discussed above throw more heat and that’s why the CPU heats up more. So, I suggest having a good, powerful cooling system if you are gonna overclock any CPU to its extreme level.
Now, after reading the four factors because of why a CPU gets hot, I hope you have understood it.

How to control CPU overheating?
Its time for how you can actually get rid of CPU overheating? Don’t worry I have some awesome tips, if you follow them, you get rid of overheating issues quickly.
I have seen multiple times people installing a fan in the wrong direction. I agree, most of the fans don’t have any directional restrictions, but in 2020, some fans have directional limitations. Like, if you are installing it in the wrong direction, it is not gonna work properly.
So, make sure your fans also support multi-direction or check their direction if they don’t support it.
Ventilation is working:
Having a proper ventilation is very very important to keep your CPU cool. Just think, if your CPU fans can’t throw the air, how the hot air goes outside.
So just make sure all the ventilations in your cabinet are still in good condition, the holes are clear. Clear the holes if they are covered with dust.
This is simple but very very effective way to keep your CPU cool.
Clean the CPU:
When we use a computer for years, the dust gathered on the CPU because of the CPU cooler. So, it is very important to clean it from time to time. Otherwise, it can also produce heat.
It is very simple to clean it-
- Just open the cabinet.
- Uninstall the motherboard if necessary.
- Open the CPU stock cooler or any custom one.
- After that clean the upper section of the CPU (don’t uninstall the CPU).
- Reinstall all the parts and done.
Most of the coolers come with pre-applied thermal paste nowadays but you should check it once and apply it if the thermal paste is not applied.
Note that, if you had applied thermal paste years ago, you can also apply it once more if you are getting CPU overheating issues.
Do you know if you overclock your processor, GPU or any other PC part, they consume more power than average? And obviously, with the increasing power consumption, the heat produced by the system parts like the processor is also increases.
That’s why it is really important to have a proper cooling system before you just start overclocking your PC.
