Hi Sharis,

You can follow the below methods to stop your fan from being loud:

1. Buy A Laptop Cooler
Due to their nature, size and increasing amounts of power; laptops seem to just get hotter and hotter. As a rule, my old laptops would generally go for a year without getting too hot. Now they’re so small and powerful that a laptop cooler is pretty much a necessity from day one.

2. Kill Your Processes
The heat generated by the CPU is generally the main heat source within a laptop, and non-vital background processes only serve to make this worse.

You can manually configure what starts up in Windows using the Microsoft System Configuration Utility.

Hit Start, find Run (you may need to search for it, depending on your particular version of Windows) and type in msconfig and click OK.

Navigate to the Startup tab and simply toggle the items you’d like to run when your computer first boots. Many update managers and system tray processes (like Quicktime, Java Update Scheduler, etc) are completely useless and simply sit there wasting your precious resources.

3. Clean your Laptop
Your laptop’s number one enemy is dust, so removing this dust not only cleans and safeguards your machine but also increases airflow which in turn will boost your fan’s efficiency. I wouldn’t recommend doing this if you’re not 100% sure what your doing.


I hope this helps.

Regards,
Lokesh.

Hi Sharis, Seeing that you\'ve already opened up and cleaned out your PC case, Mark\'s suggestion is a good option to start with. I would also recommend running an app called HWMonitor to check the temperatures on your PC. The CPU temperature in particular. HWMonitor: http://www.cpuid.com/softwares/hwmonitor.html If the CPU temperature appears normal and the fan is still running at full blast (loud), you have a problem with the fan. In this case, you will need to contact Dell about getting a replacement fan unit for your CPU Heatsink. On the other hand: If you find that the CPU is running at really high temperatures, it would be a good idea to clean out the CPU Fan+heatsink, reapply some thermal paste and put it back on. Let us know how you go with this. Good luck! James

It might be a particular application that you have installed on your computer that is using up a significant amount of RAM or CPU. Your fan will usually run hard when the temperature of your CPU gets high and this happens under high load. One thing you can do is to look at the Process Manager to work out which applications are using the most resources and you can then disable these applications to see if that fixes the problem. We have written a guide on this here: http://www.reviversoft.com/blog/2013/02/navigating-the-task-manager/

On all screenshots I see, it shows the Start Screen on the "Dashboard Tile". But for me, it shows Skype. I also don't understand the difference between the settings "Enabled", "Disabled" and "Dynamic". Only "Hidden" is obvious, and it removes the Skype tile. But the other options don't seem to make any difference...
