How to reduce the processor temperature on a PC and laptop: all methods

If your processor gets very hot during overclocking, while applications or games are running, you need to determine the cause of the problem. There are many ways to reduce CPU temperature, from simple to advanced. In this guide, we will tell you why the CPU temperature can rise, and describe all the effective ways to reduce it.

How to find out the processor temperature

How to reduce the processor temperature on a PC and laptop: all methods

Every motherboard has sensors installed that can help you find out the temperature of virtually every part of your PC. However, this must be done with special programs. In this article we explained which applications are easiest to use to check the CPU temperature, and also answered other possible questions.

What is the normal CPU temperature?

Each CPU model has its own operating temperature, but it should not exceed 90-95 degrees Celsius, as this not only negatively affects performance, but can also damage the system component.

To check the operating temperature of your processor, simply go to the developer’s official website and search for the component parameters by model or serial number. For example, for my processor the maximum operating temperature is 90 degrees Celsius. Anything higher is no longer the norm and can have a negative effect on the device in the long run.

Remove the side panel

If the processor has reached its maximum temperature and you urgently need to cool it down without turning off the device, simply remove the side panel from your PC case. This will disrupt the direct airflow coming out of the coolers, but much more cold air will enter the system and the processor temperature will drop by several degrees. Another good option in this case is to place the housing on its side so that the warm air rises and immediately leaves the housing.

Clean your PC case from dust

We all know that we should dust off our PC regularly, but few of us actually do it. Cleaning your computer is one of the best ways to lower CPU temperature quickly and cheaply. Dust clogs the heat sinks of coolers, preventing cool air from reaching the main components, and a clogged CPU cooler will require extra effort to deal with the dust layer.

In addition, cable management can also affect the temperature of components in the PC, as cooler air must reach the CPU cooler unhindered. When he has to navigate through cables and holes, less cold air enters the radiator, resulting in higher temperatures.

Optimize airflow in your PC case

If you can’t lower the temperature of the CPU and other components in your computer case, you need to optimize the airflow in your PC case. Using the diagrams below, you can increase the rate at which warm air is removed from the enclosure by supplying cool air from below and removing it from above. This creates a “tunnel” of air that draws heat away from all components in the case, including the CPU.

If your PC’s fans are installed differently than shown in the diagrams above, try rebuilding them and running a stress test on your computer. You will be pleasantly surprised.

Use a laptop cooling pad

If your laptop continues to overheat even after you clean and replace the thermal paste on the CPU, you can use a laptop cooling pad to lower the temperature and prevent the device from overheating. These stands are made of materials that can absorb and dissipate heat and are equipped with fans that improve air circulation.

Increase the rotation speed of coolers

In emergencies, you can use a fairly effective method: increase the rotation speed of the coolers on the CPU radiator. To do this, in UEFI/BIOS, switch all system fans to performance mode. Alternatively, you can do this via the CPU manufacturer’s own application. It is worth noting that in this case the fans will begin to emit a loud hum, which will disrupt the comfortable use of the PC.

Modern motherboards come with special applications that allow you to adjust the fan speed. For example, for Asus motherboards, you can install the Armory Crate program.

Replace the thermal paste (thermal paste)

If your machine is overheating (the fans are running at maximum speed but the CPU temperature isn’t dropping), applying a fresh coat of thermal grease can improve performance while lowering CPU temperatures and extending component life. To do this, follow the instructions:

  1. Turn on your computer and let it run for a few minutes before turning it off and unplugging it. Thermal paste can harden and removing the heat sink and cooler while cold may damage the processor. Alternatively, you can use a hot air dryer to heat the room.
  2. Remove the heat sink with the processor. Loosen the screws to ensure that the heat sink pressure on the CPU is released evenly.
  3. Apply some rubbing alcohol to a lint-free cloth and remove the thermal paste from the heat sink. After cleaning the radiator you can check how easy it is to remove the thermal paste.
  4. Clean the CPU thermal paste with alcohol and a cloth. Do not remove the processor and carefully remove the paste. The remaining paste in the recesses can be cleaned with a cotton swab.
  5. Apply the required amount of thermal paste to the processor and wait until the alcohol has completely evaporated. Also check that no liquid, lint, or dust remains on the processor.
  6. Reinstall the radiator block by applying even pressure.
  7. Secure the radiator by tightening the screws diagonally, a few turns at a time. This allows the thermal paste to be evenly distributed over the top of the heat sink.

Upgrade your cooling system

If none of the previous tips helped, it’s probably time to replace the CPU cooling system. This is especially true for owners of “hot” processors of the Ryzen series: buying a higher quality system will help reduce the processor temperature. In most cases, a good tower cooler or water cooling system will reduce CPU temperatures under load by more than 10 degrees.

Reduce the CPU voltage

Reducing your processor’s power consumption will have a big impact on its output temperature. For Intel processors, you can use Intel XTU or Throttlestop programs to reduce the voltage. For AMD processors, you can manually reduce the voltage or enable Eco Mode in the AMD Ryzen Master app to significantly reduce the processor’s power consumption. However, it is worth understanding that switching the CPU to AMD Eco mode will lead to a noticeable performance decrease.

Reduce the voltage on the video card

The action may seem to have nothing to do with the CPU temperature, but a discrete graphics card always affects the CPU temperature. There is only one part in a PC that can get as hot or even hotter than the processor: the graphics card. Lowering the voltage of your graphics adapter will also lower the CPU temperature, especially while gaming. But in some cases this can lead to poor performance.
