It is important to keep dust from accumulating in the computer and provide adequate ventilation to help reduce heat. Lint and dust accumulation prevents the air from flowing around the cooling fins and causes the fan to work harder.

Blocked air vents can cause serious performance issues by restricting airflow. This can cause the processor, memory (RAM), and other hardware to overheat which may lead to a potential hardware failure. Excessive heat can also cause a significant decrease in performance as most processors automatically reduce the speed of the processor to help compensate for heat-related problems.

Your Dell computer may contain one or more fans to keep the internal components cool:

• Dell desktops have more than one fan - on the processor (CPU), dedicated or discreet video card (GPU), power supply (PSU), and one or more chassis (case) fans. See the documentation of your Dell computer for more information.
• Dell all-in-one desktops and laptops may have one or more fans and may vary between different models. See the documentation of your Dell computer for more information.

Cleaning the air vents on your Dell computer

1. Turn off the computer.
2. Disconnect the power cable.
3. Check the air vents on the computer for dust or debris.
   The air vents may be located in different places. See the documentation of your Dell computer.

4. Use a can of compressed air to blow the dust or debris away from the computer.
   CAUTION: It is recommended to use a can of compressed air only. Do not use vacuum cleaners, blowers, or blow air from your mouth. Vacuum cleaners and blowers create static and may damage the electronic and electrical components inside the computer.

Follow these guidelines to provide adequate ventilation

• Place the laptop in an upright position, on a flat, and hard or sturdy surface. You must never place the laptop on the bed, blanket, or any other soft surface while working.
  CAUTION: Using the laptop on a cloth surface, a bed, a couch cushion, or your lap, can restrict or completely block the airflow. Prolonged restriction of airflow can cause overheating and potential damage.
• Place the desktop a few inches away from the wall to allow adequate ventilation.

If the issue persists, go to the next step.

A simple reboot can resolve many issues almost immediately. Restarting the computer is an effective way to clear the system memory (RAM). It ensures that any errant processes and services that have started are shut down.

Restarting the computer closes all the applications and software that is running on the computer. This includes applications running on the taskbar and services that are running in the background.

If the issue persists, go to the next step.

Overheating can occur when an application uses more hardware resources than necessary.

Windows updates can support your Windows operating system in many ways. Windows updates can solve specific problems, provide protection from malicious attacks, or even add new features to the operating system.

How to run Windows Updates on Microsoft Windows 11 and Windows 10.

1. Right-click Start and click Settings.
2. In the Settings panel, click Update & Security.
3. In the left panel, select Windows Update.
4. In the right panel, click Check for updates.
5. Restart the computer after downloading and installing the updates.

If the issue persists, go to the next step.

Running a hardware diagnostic test can help you identify hardware-related problems and provide you with troubleshooting steps to help resolve the issue. To determine if your Dell computer is experiencing a hardware problem, it is recommended that you first run a hardware diagnostic test on the computer. Dell offers both onboard and online diagnostics. SupportAssist or ePSA hardware diagnostic test helps check if the hardware devices are working correctly.

1. Restart the computer.
2. At the Dell logo, press the F12 key several times to enter the One-time Boot Menu.
3. Use the arrow keys to select Diagnostics and press Enter.
4. Follow the on-screen instructions, and respond appropriately to complete the diagnostics.
5. If the hardware tests pass, go to the next step.
6. If the hardware tests fail, make a note of the error code, and validation code and contact Dell Technical Support.

If the issue persists, go to the next step.

Dell Power Manager allows you to manage your computer’s processor and cooling fan settings. You can manage performance, computer surface temperature, and fan noise.

To learn more about Dell Power Manager features, download, and install instructions, see the Dell knowledge base article Guide to Dell Power Manager.

Dell Optimizer and Dell Precision Optimizer applications intelligently optimizes the performance on supported Latitude and Precision laptops using artificial intelligence and machine learning. It allows you to manage the laptops processor and cooling fan settings to optimize the surface temperature and fan noise.

If the issue persists, go to the next step.

Follow these tips to improve computer efficiency:

• Change which applications run when Windows starts by using the Startup tab in Task Manager.
• Close applications when you are not using them.
• Close the Internet browser when you are not using it.
• Lower the screen resolution and decrease the graphics settings if the computer becomes warmer than usual while playing games.

If the issue persists, go to the next step.

System Restore is an integrated Windows tool that is designed to protect and repair the operating system. When something goes wrong with your computer, System Restore should be used before restoring the computer to factory defaults.

If the issue persists, go to the next step.

Overheating can occur when an application uses more hardware resources than necessary. Resetting the computer to factory defaults removes any applications that might be causing this issue.

Dell computers are built with a small amount of hard disk space that is reserved for reinstalling the operating system. This method is the easiest way to restore your Dell computer to factory condition. The restoration process deletes all user data from the computer, so be sure to back up all your files before starting this process.
