How To Fix Overheating Laptop Without Taking It Apart?

Modern laptops are incredible, with so much power and capability packed into increasingly slimmer and lighter models. However, their complex designs can be an issue if you encounter one of the most common IT issues - overheating.  

You may cause more damage than good should you attempt to open up your machine on your own. If you’ve ever needed to know how to fix overheating laptop without taking it apart, this guide has all the answers. 

While it’s normal for laptops to heat up, especially when running high graphics video games or HD movies, it shouldn’t be excessively hot for an extended period of time. If your laptop constantly seems to overheat, it's important to uncover the root problem quickly, or it may impact how well your laptop can function.  

Avoid leaving your laptop in hot environments for too long, such as cars on warm days or in direct sunlight. Using your laptop in bed is also not ideal. Some effects of an overheated laptop include: 

  • Your Laptop Running Slow Or Shutting Down   
    Laptops have a failsafe if they should become dangerously hot. A standard laptop should be between 150 and 195 degrees Fahrenheit. If the CPU or GPU exceeds 200 degrees, the laptop should shut itself down to prevent damage. This will usually be accompanied by the dreaded blue screen. Regular reoccurrences of this issue are a sign something is not working as it should. 
  • Less Efficient Operation  
    The CPU may overheat if it is given too many tasks to do. As the computer then has to use extra power running the fans in an attempt to keep your laptop cool, the laptop will run programs slower than average. This is a sign that the CPU could fail under too much stress.  
  • Damage The Battery    
    Too much heat too often is not good for the lithium batteries laptops usually use. These are activated with a chemical process between differently charged ions. With added heat, this process is accelerated, meaning the batteries will wear out quicker or even expand and pose a greater risk to the laptop's ability to work. 
  • Damage The Motherboard  
    An excess of heat is not good for any part of the laptop. Especially at risk are the CPU and the motherboard. The motherboard is connected to many components that keep your laptop working, and with too much heat, it cannot work as efficiently as it cannot output the electrical current as well.

Why Do Laptops Overheat So Fast? (Possible Causes) 

Blockage in Laptop Exhaust Vents 

The most common cause of laptop overheating is dust in the fan or ventilation system, which can be found either on the side or the bottom of your machine. If the airflow is blocked, the fans cannot cool the laptop well. Regularly cleaning the fan and stopping dust and debris from accumulating in your exhaust vents is a great way to prevent it from overheating so quickly. 

Room Temperature 

Laptops should not be kept in too warm an environment for too long. The external heat will also cause damage to the laptop, making it run slower and less efficiently. 

Incorrect Laptop Placement 

The ventilation and fan system can also be stopped from working as well if it is blocked due to where you’re using it. Use your laptop on a tray, a laptop stand, or a cooling mat to allow as much airflow as possible, and if you do use it in bed, avoid placing it directly on your lap, on a pillow. 

Faulty Laptop Fan 

The fan is there to stop your laptop from overheating. A constantly noisy fan is an indicator of an internal issue causing the laptop to run hotter than usual. The laptop can also overheat if the fan itself is broken, as, without it, the laptop cannot keep cool.

If you notice your GPU fan stopped working, try turning off your laptop for a few minutes. If the problem persists, contact an IT technician as soon as possible. 

New Hardware 

There’s great appeal in adding more accessories to your laptop, such as RAM, a hard disk, and a new graphics or sound card. However, extra hardware means more processes for the laptop to run, therefore increasing the chance of overheating. It may also overheat if the hardware used isn’t compatible with your particular model.  

Underperforming Heat Sink 

If any component of your laptop stops working properly, it can impact how well your laptop works. Should the heat sink begin to underperform, it will not be as effective as cooling the CPU. 

Degenerate Thermal Compound 

The CPU is covered with thermal grease, designed to prevent air particles from being trapped between the CPU and heat sink, which would prevent the CPU from cooling as well. The thermal grease can degenerate as it ages, allowing the air particles in and causing overheating. Applying new thermal paste can help to keep the CPU cooler.

Incompatible Operating System 

This shouldn’t be an issue with a new laptop, but updates to the operating system can sometimes cause overheating.

Common Signs Your Laptop Is Overheating 

Aside from the heat your laptop will be emitting, there are other warning signs that let you know too much heat is damaging your laptop. If you notice these signs, take action as soon as possible. Should you smell burning or see smoke, stop using your computer immediately and contact the manufacturer or a laptop repair specialist.  

  • Fan Constantly Running And Making Loud Noise  
    Fans run when the laptop is getting too hot. If you notice your fan whirring louder or spinning faster than normal, this is a sign things inside are heating up. 
  • Slower When Opening A New Browser Window  
    Programs taking longer to boot up may be a sign the computer is having to work harder to keep things running. This can be a sign the components are damaged by heat or that the CPU is running too many calculations at once, therefore risking overheating as well. 
  • Lines On Laptop Screen  
    Lines on your screen may mean your graphics card is struggling, potentially due to heat.  
  • Abrupt Shutdown  
    All laptops should have a failsafe if the laptop becomes dangerously hot - they will shut down. To keep your laptop running well, be sure to keep it clean from dust and take it for routine maintenance. 

  • Hot Laptop Case  
    Heat will naturally move to a cooler surface, so should your laptop case be warm, it’s a sign that the machine inside is also on the hot side. It could also be a sign that you’ve left your laptop in a too warm place and should move it somewhere cooler. 

  • Non-specific/Unexpected Error Messages  
    Nobody likes the appearance of the dreaded blue screen error message. This is a laptop’s cry for help, so take notice and find the root of the heating issue! 

How To Fix Overheating Laptop Without Taking It Apart (DIY Guide) 

The most effective way of preventing your laptop from overheating is opening it up and fixing or replacing broken components, and clearing out all dust. However, this will void any warranties and risk further harm to your laptop if you don’t know what you are doing. These methods are short-term fixes and first resorts.  

Always consult a professional if you are worried about your laptop constantly overheating. These tips may prevent you from having to take your laptop apart.

Track the progress of these methods by downloading a temperature tracking software like MSI Afterburner, which will show how hot your computer currently is. Also, make sure to back up any data before just in case something goes wrong.  

Buy a Laptop Cooler/Cooling Pad 

The major premise of a cooling pad is that heat is attracted to colder surfaces, so the pad will take the heat from your laptop and help to cool it down. These pads can also have external USB-connected fans to add an extra cooling system for your laptop. The cooling pad is a good investment to help prevent severe overheating for longer. 

Spray Vents With Compressed Air  

Compressed air is a staple for many IT professionals. This is not a solution to larger issues with internal components or operating systems but can be a good quick fix if your big problem is dust blocking the vents.

By spraying compressed air into the vents, it can clear a path for the fan. You can also use a vacuum cleaner with great care to achieve a similar result. This is not a replacement for a good deep clean, which will require taking the computer apart. 

Turn Off CPU Booster  

The CPU running too many tasks can be a cause of overheating, so shutting down some unnecessary processes is a good idea. One of these may be the CPU turbo boost. Some feel this is not the best solution and does not let the laptop cool much, but it may be worth a try, as this process takes more power to allow your CPU to keep running tasks in the background.

You may find your laptop running a bit slower without the turbo boost, but this is preferable to it constantly overheating. This can be done by entering the Power Options in the Hardware & Sound section of the control panel if you are using Windows 10.  

Adjust Laptop Placement 

Using your laptop on the wrong surface may block the vents and allow more dust and debris to clog up the fan. Use a laptop stand, cooling mat, or lap tray when using your laptop, and don’t leave it on standby in any hot environments. 

Check Your Task Manager 

Too many unnecessary background applications or processes can overload your CPU and stop it from working as well, along with making it far too hot. Use CTRL + ALT + DELETE to access the task manager and determine which processes are draining the power. Google any you don't know the purpose of to prevent you from canceling anything vital to the computer's performance. 

Dim Screen Brightness 

This is another easy method to give your poor overworked laptop a little break from running at full capacity.  

Cap Frame Rate On Video Games 

If your laptop is used often for gaming and you notice an increase in temperatures while you play, this solution may be for you. This will not be useful for competitive games that need you to be accurate with a mouse, but they will help with other types of games. In your game’s graphic settings, enable V-sync.

This will lock the game’s framerate to your monitor’s refresh rate, only showing the frames you need and saving laptop resources and power. Give your poor graphics card a break!
