What is the fix for this?  My new 5480 is driving me crazy.  It never shuts off the fans when plugged into USB-C.

Re: Dell 7480 and Dell 5480 fan noise and heating issue on m

My Latitude 7490 had the same symptoms, fan running all the time and the system was hot. In the Task Manager I could see that the WSAPPX process was taking much of the CPU time, at minimum 25%. Via Google I found instructions to change in Local Group Policy Editor setting both for Computer Configuration and User Configuration:

> Administrative Templates > Windows Components > Store > Enable the Store application

These were originally set to "Not configured", so it seemed ambivalent. Setting to Enable made the WSAPPX to behave, running only immediately after start up to check the updates for apps installed via the store. The original instructions said to disable the setting, but then you don't have the Store, so this no option.

But my 7490 is still having big problems with the 1803 update, still waiting for MS to come up with a proper update... =(

I'm only seeing 2% CPU usage and the fan is still way too high.  Speedfan reports temps of 35C.  It works properly when not plugged into USB-C dock, but 95% of the time I use it docked.  My room used to be silent, but now all I hear is this annoying laptop.  My previous 5 Dell laptops didn't have this problem.

My Dell Latitude 7480 never seems to run the fans, i keep getting freezes and even blue screens more frequently as i use it for longer and longer (all withing, eg. 3-4 hours. yesterday i had 3 blue screens and 1/2 freezes within 5 minutes as soon as my mom logged into the computer.)

We have primarily 7480's and 7490's and all are experiencing issues with the the fan running so loudly.

We also have a bunch of users using E7470's and they have no issue with the fans. 

I myself have a 7480 and I too experience the exact same issue.

I have also tried setting the fan to "quite mode" via the "Dell Power Manager" and this definitely reduces it at he time, but it kicks up again later on.

Have you found a solution yet?

I have a Dell 5480 with quad-core CPU and I am having the exact problem that you guys are having. I just wonder if replacing the CPU fan will help ?
