How To Lower CPU Temp

Dirty Computer Fan

Has your computer suddenly shut down due to overheating? It happens for several reasons. But the main one is that the processor runs many operations at once. Playing games for a long time can also result in a high temperature of the CPU. Then, how to reduce CPU temperature? 

Quick Answer

There are several methods to prevent overheating from occurring. You can get an upgraded CPU with lower temperature features, enhance the cooling around the processor, clean the computer, do a maintenance check on the internal system of the CPU, and more. 

You might want to understand the dangers of overheating and learn a few tips and tricks on the matter. Let’s start with simple ways to reduce the CPU’s temperature.

The Dangers of CPU Overheating

It is a common stance that whenever an electric gadget heats up, it is bound to stop working eventually. So, any gadget and computer should stay at a lower temperature.

For a PC, the dangers start in the motherboard. All the motherboard components will heat up if a computer is overheating. As a result, their function optimization will decrease, and they will inevitably crash down. 

Many computers of the recent era are designed to shut down if the temperature reaches a certain threshold automatically. If your PC needs to be manually temp-controlled, you can try a few methods.

5 Simple Methods to Cool Down the CPU

Here are a few easy ways to reduce the temperature of the CPU.

Method #1: Better Airflow System

The most effective method is to upgrade the airflow mechanism in the CPU. All the CPUs have a ventilation system that runs the airflow from inside to outside the CPU. If this mechanism runs effectively, the heat is released out of the system.

However, it would help if you upgraded the airflow mechanism. Because the CPU components often run in parallel, which allows for overheating to a more significant degree. 

Hence, you can install intake and exhaust fans to prevent the heat up. For this, you need to ensure that you place the fans correctly. 

The intake fans are responsible for the air inflow, while the exhaust fans are responsible for the outflow. Although larger fans are preferred, you can check the instruction manual for suggestions.


The outflow from the exhaust fans should be similar, if not exact, to the inflow from the intake fans. This is important because if the air pressure on one end is larger than the other side, it could result in your CPU overheating.

Method #2: Manage Your Cables

You probably did not even think about this as a solution to your problem. But it will surprise you that cable management plays a vital role in lowering the overall temperature of the CPU.

The thing is that cables take up a lot of space. Adding new accessories is undoubtedly an exciting part of the day. But in that excitement, we forget what happens behind the scenes can disrupt the functional performance of the computer.

In this case, the messy cables can disrupt the airflow of the internal system. However, if you manage them well, it will appear TikTok worthy and beneficial for the CPU.

Method #3: Clean Your Computer

Another clogging material is dust. It can be set up around the components, minimizing the airflow and eventually overheating the system. The biggest victim of dust is the fans because, with the airflow, the dust settles inside. 

All you need is an effective vacuum cleaner or a can of compressed air and remove the dust from the CPU. Both of them work effectively. However, it would be best if you took up the habit of doing this frequently to save the CPU from dust buildups.

If you do not know how to clean your PC, here is how:

  1. Open up the computer case. You will need a screwdriver. 
  2. Clean the dust off the fans using a dry rag.
  3. Remove the dust using a vacuum cleaner or compressed air.
  4. Put back the computer case.

Method #4: Place the System in a Ventilated Room

Most of the time, you have done everything to upgrade the airflow of the CPU. But the place where the CPU is located is not well-ventilated.

This causes the CPU to overheat. 

Hence, you should find a place where cool air can come into the room. Otherwise, your upgraded airflow mechanism would do you no good.


A temperature above 85 degrees is harmful to the computer. Moreover, if it happens frequently, you should take note of it.

Method #5: Run a Maintenance Check

You must run a maintenance check on your PC every few weeks. Especially if installing new fans and cleaning the CPU did you no better than before to reduce the heat.

There are a few things that you can upgrade. 

Operate your fans at higher speeds by using programmed software. They are available online, but it is better to review and research before you pick one for the job.  

Between the CPU and heatsink, there is a thermal paste that dries off after some time. By reapplying it, the system should work normally. Here is what you will need to do:

  1. Remove the CPU cooler.
  2. Use a razor to scrape off the excess between the CPU and the cooler.
  3. Then, use alcohol and a rag to clean the point of contact thoroughly.
  4. Apply a small amount of thermal paste and spread it around.

If your PC has been here for a couple of years, upgrading your CPU cooler, power supply, or even purchasing new case fans is better. 


Liquid cooling kits are another amazing way of reducing the CPU’s heat. This is your best bet, especially if you are a gamer, a programmer, or a person working with overclocked components. Plus, they are safe. However, you will need to do the proper research before buying one. 


To wrap it up, you should check the CPU temperature. If it feels like it has been overheating recently, it is time to either upgrade the system or buy a new one. We hope that our blog was of aid to you in this matter.
