If you think your computer is getting hot, you probably don’t think so. The most common cause of computer overheating is the CPU (CPU).
What are the symptoms of overheating?
If the computer runs smoothly, there is no need to worry about overheating. That one or more components are overheating is indicated by the following symptoms:
- Computer restarts. This most often indicates overheating of the CPU;
- performance programs close spontaneously;
- Computer turns off by itself. This indicates that the power supply or motherboard is overheating;
- Blue Screen of Death (BSOD). The error code displayed on the screen helps to determine which component is overheating accurately;
- An artifacts appear in performance games. This indicates that your graphics card is overheating or malfunctioning.
It is important to note that it is not always the problem of overheating components when the above symptoms are mentioned.
Internal elements of the system unit – processor, video cards, hard drives and others fail on overheating, which should be obvious for any computer user. The higher the system performance is required, the harder it loads and warms up to peak values. Cooling systems, including all kinds of coolers, are responsible for cooling the computer elements. If the components overheat anyway, there are consequences.
The surest way to know the maximum allowable CPU temperature is to see the device specification on the manufacturer’s website for your specific product. In addition to listing all specifications, it will also list the maximum operating temperature.
Don’t think it’s okay if you have a stable 90 °C at 95-100 °C max. Optimally, the temperature should not exceed 60-70 °C during the load (games, rendering), unless it is some kind of special stability test with excessive load, which in everyday life will never meet.
Many devices now have Turbo Boost technology.
Example, if the base frequency of AMD Ryzen 3700X is 3.6 GHz, then in Turbo Boost mode it can operate at 4.4 GHz under certain conditions. One of these conditions is temperature.
If the optimal temperature is exceeded, the maximum frequency can be slightly reduced. When the temperature is nearing the maximum allowed temperature, the frequency drops more sharply. This ultimately affects the performance, which is why the optimal temperature is considered 60-70 °C.
High processor temperature in idle mode may indicate that the system has hidden “miners”. Normally, the CPU in idle mode should heat up much less than in the load.
If you sum it up, it turns out that the normal CPU temperature is very fuzzy and there is no accuracy in this regard.
See, you can be 100% relaxed if your CPU temperature is in this range: .
- in idle mode – about 40-50°C;
- under load – about 70-85°C
Processor temperature in degrees Celsius
|Up to 50||Normal at average load.|
|Up to 65||Normal in heavy games, video editors and other resource-intensive programs.|
|From 65 to 70||Close to the critical point. It is good to check the coolers.|
|Ot 70||This leads to system instability. Computer can brake.|
|Ot 80||Pre-critical state. You should check your PC as soon as possible and do not use it until the problem is solved.|
How do I see the CPU temperature?
A temperature sensor is integrated into the processor, as with some other components of your computer. You can see the temperature of the processor in the BIOS, but if you do not want to dig into it or do not know how to enter the BIOS, the best option for you will be to download a special program for this.
You can do it through AIDA64
How to reduce CPU temperature?
- Clean your computer from dust. And this applies not only to the cooling system, but also to the other components.
- Change the thermopaste.
- Add case coolers. Processor temperature is also affected by the temperature inside the case. The faster hot air goes out and cold air enters the chassis, the better. The main rule of thumb is that a hot-flow system should be more powerful than a blowing system. This is much more efficient than if it were the other way around.
- Adjust the cooler speed according to the load. The busier the CPU is loaded, the more fans must spin. There’s no need to set 100% of cooler revolutions on a permanent basis.
- Swapping coolers for more powerful ones. For notebook owners, a cooling cooler stand will be an option.
With video cards, everything is about the same. Only in addition to the information in the specification, you can see the maximum temperature values sewn in Bios devices.
For both manufacturers, depending on the series of graphics cards, the maximum temperature ranges from 89 to 105 °C.
You can view them using the GPU-Z or AIDA64 software.
In addition to the temperature of the core itself, the temperature of other components of the video card is also important: video memory and power circuits.
As with processors, the temperature has a direct effect on the maximum frequency during operation. The higher the temperature, the lower will be the maximum Boost. That’s why you should pay attention to the cooling system when choosing a video card, because during the game it is always 100% loaded.
Many users save money on this component when building their PC, which can lead to the death of other components, and in some cases – even a fire. It’s not an option to take the power to the PSU. A 20-30% margin is the minimum that guarantees the stable operation of your computer. It may also eliminate the need to replace the device during an upgrade.
What should be the temperature of the PSU? Everything is different, but usually heating to 80°C is normal, but ten percent higher is already a cause for concern. For some time, the unit can also work in hot conditions, but not for long.
Watch the temperature of your computer, do not let it overheat, or burn at all. And by the way, all temperatures in this article are for desktop computers. For laptops, they may vary, but slightly.
