Is your PC running slower than usual? Overheating can lead to performance throttling and even damage your components over time. If you're wondering how to check PC temps Windows 10, you're already on the right track to better system health. Often, a system bogged down by unnecessary junk files can be a contributing factor to increased workload and heat.

This guide will not only show you where to monitor your temperatures but will also provide a comprehensive look at how to clear temp files in Windows 10 and 11. By cleaning out this digital clutter, you can free up valuable disk space, improve responsiveness, and potentially help your PC run smoothly.

Where can you check PC temps on Windows 10?

Before we dive into cleaning, let's address the core question of monitoring your computer's temperature. Knowing your PC's temps is crucial for diagnosing performance issues.

Windows 10 and 11 have a limited built-in feature for this. You can check your graphics card (GPU) temperature directly from the Task Manager.

Step 1. Press Ctrl + Shift + Esc to open the Task Manager.

Step 2. Click on the "Performance" tab.

Step 3. In the left-hand column, you should see your GPU listed. Click on it, and its current temperature will be displayed in the stats panel.

However, this method doesn't show your CPU temperature, which is a vital metric. To see your CPU temperature, you'll typically need to:

Check the BIOS/UEFI: Restart your computer and enter the BIOS/UEFI settings (usually by pressing F2, F10, or Delete during boot). The temperature is often displayed on the main or hardware monitor screen. This isn't convenient for real-time monitoring while using Windows.

Use Third-Party Software: The most common and effective method is using free third-party monitoring tools like HWMonitor or Core Temp. These applications provide detailed, real-time temperature readings for your CPU, GPU, and other components directly on your desktop.

Once you have a baseline for your temperatures, you can take steps to improve them. One of the easiest first steps is cleaning up unnecessary files that can cause background processes to work harder.

How to clear temp files and folders on Windows 10/11

Windows includes a built-in utility called Disk Cleanup that is designed specifically for this purpose. It’s a safe and reliable way to clear temp files in Windows 10.

Step 1. In the search bar, type "Disk Cleanup" and open the application.

Step 2. Select the drive you want to clean (usually your C: drive) and click "OK".

Step 3. The tool will scan your drive for files it can safely remove.

Step 4. In the Disk Cleanup window, scroll down the list and check the box next to "Temporary files". You can also select other items like "Recycle Bin" or "Thumbnails".

Step 5. Click "OK" and then "Delete Files" to confirm the action.

For an even deeper clean, you can click the "Clean up system files" button, which will rescan for more files, including old Windows Update files.

Is it safe to delete temp files?

Yes, it is generally very safe to delete temporary files. These files are created as temporary storage for information and are not needed once the application or process that created them is closed. Deleting them will not cause any harm to your operating system or your installed programs.

In fact, cleaning them out is beneficial. It frees up disk space, can resolve certain application errors, and helps maintain a clean and efficient system. The worst that can happen is that a program might take slightly longer to open the next time as it recreates a necessary temp file. The operating system will protect any files that are actively in use, which is why you may see a "file in use" error when deleting them manually.
