Computer Heats Up Room: 4 Reasons and Solutions

If you notice your room getting warmer and can’t find a reason, it may be your computer. Computers tend to give off a good amount of heat to keep their system from overheating. This can lead to a warm area around your computer and even a warm room. 

When a computer heats up a room, it may be caused by an efficient computer cooling system, a poorly ventilated room, an overworked computer, or a PC that uses too much power. Solutions include moving the computer to a bigger room, using fans, turning off the computer, or optimizing its performance.

Let’s take a closer look at these 4 reasons that your computer can heat your room and some possible solutions. 

1. The Computer’s Cooling System Redistributes Heat Properly

As electricity is sent through your computer, it produces heat. The heat comes from the resistance met as the electricity flows through wiring. Like any other electrical object in your home, heat is a natural part of making it work properly. Computers can produce a lot of heat because they require many different electrical components to work, and the more powerful your computer, the more heat it will produce. 

As part of the normal process of keeping your computer from overheating, all the heat that is made within the wiring is vented out by fans. The heat has to go somewhere so it is not trapped within your computer as this could cause many issues. That output of heat is strong and can cause your room to heat up. While this is a sign that your computer is working properly, it is also annoying during the warmer months. 

How Can I Fix This?

While this is annoying, it is important to understand that this indicates your computer is running properly. You could consider moving your computer to a larger room for the heat to not be as trapped or noticeable. 

2. The Room Is Not Well-Ventilated

If your computer room is not well-ventilated, you will feel the effects of the hot air coming from your computer. This is especially true for rooms that regularly have the doors and windows closed as the air will not circulate as well in these rooms. 

Think of your computer as a space heater. If you leave a space heater in a room with a closed door and shut windows, it will heat the room much faster. This is how it works for your computer as well. If you are running air conditioning through your house and still notice the rise in temperature of your room, then you know it’s not something that AC can fix without your bill going up. 

Possible Solutions for This

You can consider moving your computer to another room with better ventilation or just making sure that the room is ventilated with open windows or doors. Don’t try to turn up your air conditioning too much as it will raise your bill, but you could install some fans to get the air properly circulating throughout your home. All it takes is for the air to not remain stagnant. This will help keep your room cooler despite the heat coming from your computer. 

3. Your Computer May Be Overworked or Left On Too Long

The more your computer runs, the hotter it is going to get. We may not always have a choice as to how long we spend on our computers depending on work and other obligations, but using it less will lower the amount of heat coming from it. 

The same goes for leaving it on for extended periods. Sure, it is nice to just jump on whenever you need to, but anytime your computer is running, there will be heat emitting from it. Your computer will use less energy to run when you aren’t currently using it, but that doesn’t mean it isn’t using any. Things like updates and downloads can keep your computer running long after you have logged off. 

So, What’s the Answer?

Make sure at the end of the day you are shutting down your computer, so it isn’t emitting any extra heat overnight. Just shutting your computer screen off isn’t enough to keep it from working while you’re away. So, shut it down completely to prevent the heat from continuing overnight. 

Also, attempt to limit the time spent on the computer throughout the day. Sometimes this isn’t easy for those who work remotely, but any time spent away from your computer is a chance for the room to cool down. 

4. The Computer May Be Too High-Powered

Another common reason your computer makes your room so hot is that it may be a high-power computer that uses a lot of heat to work. If you use your computer for gaming, for example, you need a high-powered computer to download and play those games. The more power your computer uses, the hotter it will run, and high-power computers will use a lot of energy. 

What Is a Possible Solution for a High-Power Computer?

Depending on what you use your computer for, you could consider a downgrade, but your new computer may not give you all the capabilities that you need or want. So, if a downgrade is not an option for you, then you may want to consider monitoring how much energy your computer uses. 

There are so many different programs running on your computer simultaneously that you may not know about. Make sure to check for any unnecessary programs running in your task manager that you aren’t actively using, as this can cause your computer to work harder and produce more heat. 

Frequently Asked Questions

Is It Normal for a PC To Heat Up a Room?

It is completely normal for your computer to heat up a room. The heat your computer produces comes from transferring power through wires and meeting some natural resistance. The energy used to combat the resistance creates heat. The more power your computer uses, the hotter it will get. 

In order to keep your computer from overheating, there are fans in your computer that push the heat out. So, if you notice that your room is warmer, that means your computer is working properly and moving the heat outward to prevent the system from overheating.  

How Can I Cool Down My PC Room?

While you’re not going to fully be able to control the heat your computer produces, there are ways to still keep your room cool. 

To cool down your PC room, air it out. Keep the door open and try opening a window if it’s cooler outside. Get air circulating into your room in any way you can. This can be done with open windows, fans, or air conditioning. Moving air will help control the temperature in your room. 

Check for any unnecessary programs that are running on your computer in the background. This can cause your computer to use more energy to run and emit more heat. Also, make sure to turn off your PC when you are finished, so it is not constantly running. Other than that, your focus should be on the room rather than the computer.

So, get the air moving for the best results when dealing with a hot room. 


When a computer heats up a room, it could indicate that the computer’s cooling system works properly, the room is not well-ventilated, the computer is overworked or too high-powered. You can cool down the room by airing it out, or you can reduce the heat from the PC by optimizing its performance.

By knowing what to look for and how to fix these issues, you can resolve any problems caused by a room heating up due to your computer.
