Whether you’re talking about a desktop PC or a laptop, when the fans start spinning at full speed, it means that the computer is experiencing some kind of problem, especially when the computer is not performing any demanding tasks such as playing games or exporting videos, which are processes that require a lot of resources.
When the fans are turned on full speed, it means that the PC is using a large number of resources, either the graphics card and the processor or only one of these. On the Internet we can find a large number of applications that allow us to know the number of resources that the PC is consuming, resources that affect its performance. However, it is not necessary to use any of those applications since Microsoft offers us the application Task Manager to detect the problem and solve it.
Detect which application consumes the most resources
The first thing we should do when we notice that the fans are going full blast is to access the Task Manager in the Processes tab, check which application is consuming resources. It is easy to identify them because they are shown in orange if the consumption is medium or in red if the resource consumption is very high.
To prevent the computer from continuing to consume resources, the first thing we must do is select the application with the mouse and then click on the button Finish homework, button located in the lower right corner. At that moment, Windows will close the application and it will be time to look for what could be the problem that is causing the high consumption of resources.
As we can see in the image above, the origin of the problem lies in Microsoft’s default Windows browser and which, personally, I recommend, especially for users who work from home and/or want to have the entire ecosystem of applications and operating system in a single place without depending on external applications.
The reason why Edge is consuming a large number of resources is due to an endemic problem with Chromium, the basis of the Chrome browser, although Microsoft has been able to provide a solution. However, Chrome, based on this same project, is a real resource eater on any computer and operating system, so if you do not use Edge and use Chrome this may be the cause.
Which applications consume the most resources in Windows?
It is very rare to find applications that increase the resource consumption of any PC other than browsers, unless the application we are using is performing some process at that moment. Browsers have the habit of updating all the tabs they have open in the background to be ready for when the user visits them, which implies a very high consumption of resources especially when the number of open tabs is very high as is the case of the example I have used for this article and where I had 35 tabs open.
If we detect that an application, without performing background processes, has a large number of resources, it means that is not optimized for the version of Windows we have installed. The solution here is to look for an alternative or check if there is a new update pending download.
