Why is my Intel processor overheating?

There are few things that terrify PC owners as much as an overheating CPU. It’s a problem that ranks right up there with the Blue Screen of Death in terms of issues that can signal serious problems for your computer. While any computer can experience CPU overheating, fortunately, most of the reasons for it are easy to check. These causes apply to Intel processors, but also to those from AMD or any other manufacturer.

On Intel PCs, a good indicator that your processor is overheating is if the computer crashes or shuts down shortly after powering on. CPU throttling, low clock speeds, and general system sluggishness are also reasons to check your computer’s temperature. Many PCs have software, such as Corsair iCue, that manages cooling systems and tracks temperature data. There are also a host of other software available for CPU monitoring. If your computer isn’t overheating yet but you’re still experiencing performance issues, you can check out some of our great tips for making your CPU run better.

Whether or not you’re experiencing overheating, it’s helpful to know the common causes of this condition so you can diagnose problems in the future and avoid mistakes. From cooling system quirks to faulty fans and cramped cases, here are five causes of Intel processor overheating.

The first thing to check if your computer’s CPU is overheating is to see if your cooling method is working and if you have a powerful enough cooling solution. The two main cooling solutions for PCs are air cooling and liquid cooling. In an air cooling system, a heat sink helps transfer heat away from the CPU, before cooling with fans. While air cooling is the most common form of cooling, it is not the most powerful. Liquid cooling systems are the other popular choice for consumer PCs, consisting of a coolant that absorbs the heat and a radiator that exposes the liquid to the air.

When it comes to air cooling, make sure you have the right size cooler, that the bracket screws aren’t overtightened, and that all fans are operational. For liquid coolers, make sure you’re using the correct radiator size for your build and that there are no coolant leaks. Additionally, liquid coolers work best with the radiator mounted at the top of the case rather than on the side.

Also, check that the thermal paste is not misapplied. Make sure you are not using too much or too little. A general rule of thumb in the PC building community is to use about the size of a green bean, spreading the paste evenly over the CPU. Make sure you are using the best thermal paste for your PC. Also, you should change your PC’s thermal paste every three years on average.

If you regularly overclock your Intel processor, it could be causing it to overheat. Overclocking your processor refers to the practice of increasing its clock speed, which is the number of calculations it performs in a given amount of time. Processors come with factory clock speed settings to prevent them from having a short lifespan, as working at the highest clock speeds they are capable of would mean that they won’t last as long. Increasing these clock speed settings to the actual limit is a great way to get extra performance in games and other intensive tasks, but in the long run, it can seriously harm the processor.

Think of your processor as an employee in a company. If that employee is constantly overworked, it may meet your expectations for a while, but eventually it will burn out from the constant overwork and will no longer perform at all. Similarly, overclocking is not something you should subject your processor to on a regular basis unless you want to drain the life of your CPU. In addition to causing a higher than normal risk of overheating and failure, overclocking can also void the warranty on an Intel chip, leaving you with no recourse in the event of a replacement.

To optimize the thermal efficiency of a PC, you need to pay close attention to airflow. In the case of a desktop PC, this means that the computer case must efficiently draw air from the outside and expel hot air. This is why you will often see so many fans in powerful desktop computers, because the air in these systems heats up quickly and needs to be expelled as quickly as possible.

The type of case your computer is in can have a big impact on its thermal performance. The best type of case for optimal airflow is a mesh case, in which the front of the case (and in some cases the top and sides) are made of a woven metal mesh that allows for seamless airflow while keeping out dust and debris. A closed case can lead to overheating, but when combined with improper or insufficient cooling, the problem can be compounded. Regardless of the type of case you use, make sure all fans are clean and working.

If you’re using a laptop, its chassis is specially designed to allow airflow. If your laptop is overheating, make sure none of the intake or exhaust vents are blocked or obstructed. Although they’re called laptops, many of them have vents on the bottom that get blocked when the computer is placed on your lap, leaning on a flat surface like a table to give yourself some breathing room.

A PC’s cooling systems have the tireless task of drawing in cool air and expelling hot air. However, if your computer is sitting in a hot room or outside on a hot day, there won’t be any cool air to draw in. Instead, the system will be drawing in hot air from your surroundings, which can easily overheat any processor, including an Intel one. While it may be tempting to take your laptop to the pool or beach for a remote work session on a hot summer day, it may not be able to handle the heat. Even indoors, the room can get too hot, meaning your computer’s fans are sucking up all that heat and your already sweaty CPU is getting burned.

If you’re outside on a hot day and notice your CPU overheating, bring the computer inside immediately. Desktop owners should also be aware that if you place your well-cooled PC in a computer cabinet or other enclosed space, you’ve just created a larger, unventilated container around your case that will continue to trap heat. Even an entire room may be too small to dissipate the heat from a powerful PC. If you have a gaming PC or high-end workstation running in a small dorm room or bedroom, you shouldn’t use it for long periods of time without the ventilation of cooler air, such as by running the air conditioner or opening a window or door.

Your BIOS is the instruction set that your motherboard uses to boot your computer and start your operating system. It’s also where you’ll find settings for how much power the chip can draw and how fast your fans spin at different CPU temperatures. While these settings aren’t a problem for the average user, it can be helpful to check them if your CPU is overheating. Some high-end systems may have voltage settings enabled by default that cause a chip to run outside of its thermal design power (TDP). These settings are often called Turbo Boost, and turning them off can improve the CPU’s thermal performance. It’s also essential to make sure that the fans spin up aggressively when the CPU gets hot.

It’s important to note that while high voltage settings can push a struggling CPU to its limit, an overheating incident can be caused by a combination of BIOS settings and other reasons. Once you’ve made sure your BIOS is configured correctly, check for other issues. It’s easy to make a mistake when changing BIOS settings if you’re not familiar with PC configuration, which could lead to other issues. The right BIOS settings for your PC depend on the model of processor and motherboard you’re using. Additionally, each manufacturer has a different interface and terminology for their custom settings.
