How do you know if your PC is overheating?You can tell your PC is overheating if it feels hot to the touch, if your fans are running loud, or if you experience abrupt shutdowns, screen freezes, or the dreaded blue screen crashes. CPU overheating issues tend to happen the most when performing resource-intensive tasks like gaming or video editing. All electronics are prone to overheating. This can be extremely damaging to both software and hardware, and most PCs have components in place for heat dispersion and ventilation to prevent overheating. If your computer feels hot or the fan gets loud, you may have too many browser tabs open, or you may be doing intensive tasks like playing games, editing multimedia files, or streaming videos online. If your computer is hot but otherwise working fine, give it a break and close the resource-intensive app for a while. Common reasons why your PC is overheating
Computer overheating is usually caused by multiple factors. Dust, if left to build up over time, can block the fans and cause the CPU or GPU to overheat. Too many applications running at once can cause the fans to go into overdrive, and if this happens too many times, the fans might stop working. How to cool down your computerThe best way to cool down your computer is to first figure out why your PC is overheating. Once you’ve identified the causes of the excessive heat, you can figure out what to do next — whether you need to physically clean your PC, improve airflow, or close some browser tabs.
How does computer cooling work?Most computer cooling works by using air flow. The vents in your computer’s exterior casing allow cool air to enter while releasing the hotter air from inside. Fans facilitate air flow — and an increased whirring sound indicates your device may be a little too hot, as the fans are working overtime to keep things cool. Other internal components also help with cooling. These are usually attached to the CPU or GPU, which generate the most heat through typical use. The heat sink is the main component that absorbs heat from these processors, and thermal paste is applied to the heat sink to conduct heat away from the CPU. Your PC also cools itself systematically. This is what’s happening when you hear the fans speed up when opening certain applications or doing certain tasks. Cooling software provides automatic mechanisms to increase cooling when performing demanding tasks over an extended period of time. How to prevent your PC overheatingTo stop your computer from overheating, check both the physical and software components. Many solutions to computer overheating — like identifying resource-hungry apps, closing background programs, monitoring physical usage and heat exposure, updating your software, and scanning for malware — will also keep your PC cool in the long run. When trying these techniques, be sure to monitor your CPU temperature to make sure everything is working properly. Identify demanding applicationsSome applications require a lot of computing power, which can cause your computer to overheat. You can solve this computer heating problem by checking your applications to see how much computing power they take up. On Windows 10 or 11, the Task Manager shows which applications are the most demanding. Access the Task Manager by going to the Start menu or using the shortcut Ctrl + Shift + Esc. It usually opens up in Compact Mode, so click More details at the bottom-left corner to see more. The Processes tab lists all the processes running on your PC and shows you the amount of computing resources used by each. If an application is using up a high CPU percentage, then that may explain why your PC is overheating and slowing down. Close the application and open it again later, when you have fewer apps running. To close resource-intensive programs and background processes, highlight a particular app and select End task at the bottom right-hand corner of the Task Manager window. To prevent computer overheating, try to use only one resource-intensive app at a time. Minimize the amount of open tabs in your browser, since each new tab consumes more RAM — especially if you’re playing video games or using web-based tools. Close background apps and delete temporary filesRestrict background data and delete temporary files to preserve your computer’s resources and save storage space. A special cleanup program can keep your PC running in top form. AVG TuneUp is specially designed to find junk files and other useless data taking up space in your PC. Unnecessary programs and other bloatware can cause your PC to slow down and heat up quickly. AVG TuneUp seamlessly maintains your computer’s performance on a regular basis, making it a no-sweat solution for keeping your PC’s operating system clean and its hardware cool. And the patented Sleep Mode automatically snoozes apps when you’re not using them — preventing unnecessary tasks from eating up valuable CPU and RAM resources. Optimize your GPUYour GPU will have different optimal settings depending on what it’s being used for. To optimize GPU performance for a particular app, open the graphics settings in your system settings — find it by searching for it in the desktop search field. Depending on what you’re doing, you can optimize graphics for video games, video editing software, or your browser. Keep your GPU cool by ensuring that your entire device is clean and dust-free, and that the fans are running as they should. You can install extra fans or another cooling system if your GPU tends to run hot. You can also monitor your GPU’s temperature to track when it heats up. Physical usageJust as dust and poor airflow can cause PC overheating, using your PC in direct sunlight can also cause your PC to overheat. Without adequate ventilation, even moderate air temperatures can heat up your PC. The best way to reduce any physical impact on your device’s ability to stay cool is to clean it regularly, keep it out of direct sunlight, and ensure the vents are exposed to air. To clean your PC and keep it free of dust, use canned air and a microfiber cloth. Be sure to clean out the nooks and crannies, where the dust tends to get in. Check for updatesUpdating your PC and the software on it can also minimize computer overheating. Updated programs run faster and more smoothly than older programs, and they’re more secure — any exploitable vulnerabilities found will most likely have been patched up in the newest version. In Windows 11 and 10, check for updates by opening the Updates & Security panel in the System Settings. Windows Update will show whether your PC is updated — but regardless of what your computer says, you can check for updates anyway, then download and install any updates available. Check for malwareIf your computer is overheating, you should also check for a virus or other malware. Many types of malware will rip through your computer’s resources and cause severe overheating. A quick virus scan can tell you whether it’s malware heating up your PC. Install reliable antivirus software to prevent viruses and other malware from infecting your PC in the first place. The best antivirus apps double as virus and malware removal tools that will detect and remove viruses automatically. PUPs (potentially unwanted programs) are not malware, but they do waste valuable disk space and can slow down your PC. A trusted PC cleanup tool will find and delete these programs and other unnecessary software. Prevent overheating with AVG TuneUpRegular maintenance is essential for keeping your PC in top shape. Like any other machine, computers benefit from regular cleaning. But caring for your PC’s physical components is only half the battle. AVG TuneUp performs regular and automatic maintenance, cleaning out browser cookies, unneeded software, cache items, and junk files to keep your PC optimized and protect it from overheating. Speed up your PC and keep it cool with AVG TuneUp. What prevents computer from overheating?Thermal paste is a highly conductive material usually used to coat components such as the CPU and GPU. Thermal paste helps to dissipate heat more efficiently and prevent temperatures inside your machine from reaching critical levels.
What component inside the computer case is used to draw heat away from the CPU?The heat sink has a thermal conductor that carries heat away from the CPU into fins that provide a large surface area for the heat to dissipate throughout the rest of the computer, thus cooling both the heat sink and processor.
What is a component used to exhaust the hot air produced by the CPU?Fans. Fans are used when natural convection is insufficient to remove heat. Fans may be fitted to the computer case or attached to CPUs, GPUs, chipsets, power supply units (PSUs), hard drives, or as cards plugged into an expansion slot. Common fan sizes include 40, 60, 80, 92, 120, and 140 mm.
