    1Causes of CPU reaching 90 degrees on startup

    When it comes to your computer’s performance, there’s nothing more frustrating than noticing that your CPU is running at a high temperature, especially when it happens right from the start-up. There are a number of reasons why this might be happening, and it’s important to identify the cause in order to take the appropriate steps to fix the problem. So, let’s dive in and take a look at some of the common causes of a hot CPU on start-up.

    One of the most common causes of a hot CPU is overclocking. Overclocking is the practice of running your CPU at a higher frequency than it was designed to run. While this can lead to improved performance, it also puts a lot of stress on the CPU, and can cause it to run at a higher temperature. If you suspect that overclocking is the cause of your hot CPU, the solution is simple: reduce the frequency of your CPU to its default settings.

    Another common cause of a hot CPU is poor air flow inside your computer case. A lack of proper ventilation can lead to a build-up of heat, which can cause your CPU to run at a higher temperature. To fix this problem, make sure that your computer case has adequate ventilation and that the fans are working properly. Additionally, you might want to consider adding additional fans to improve the air flow inside your case.

    Dust build-up inside your computer is another potential cause of a hot CPU. Dust can accumulate inside your computer over time, blocking air vents and making it difficult for heat to dissipate. To fix this problem, you’ll need to open up your computer and clean out the dust. You can use a can of compressed air or a soft brush to remove the dust.

    High ambient temperature can also cause your CPU to run at a higher temperature. If your computer is in a room that gets very hot, the heat will transfer to the computer’s internal components and cause the temperature to rise. To fix this problem, you’ll need to make sure that your computer is in a cool, well-ventilated space.

    Faulty thermal paste or thermal grease application is another common cause of a hot CPU. Thermal paste or thermal grease is used to help transfer heat away from the CPU and into the cooling system. If the thermal paste or thermal grease is not applied properly, it can cause heat to build up and cause the CPU to run at a higher temperature. To fix this problem, you’ll need to remove the CPU and reapply the thermal paste or thermal grease.

    A defective CPU or cooling system can also cause a hot CPU. If your CPU or cooling system is not working properly, it can cause heat to build up and cause the CPU to run at a higher temperature. To fix this problem, you’ll need to replace the defective component.

    In summary, there are many different reasons why a CPU might reach 90 degrees on startup. It could be due to overclocking, poor air flow, dust build-up, high ambient temperature, faulty thermal paste or thermal grease application or a defective CPU or cooling system. By identifying the cause of the problem, you can take the appropriate steps to fix it and get your computer running at optimal performance.

    2Symptoms of high CPU temperature
