Dell XPS 13 9380 fan problems solved

My new XPS 13 9380 would very often have the fans blowing when plugged in, even though not doing anything too intensive.

>> Solved by removing  Killer wireless software and driver (version and using the driver version automatically installed by Windows and updates (version )

For the first few days I put it down to windows updates, AV heuristics, and other imaginary teething problems but then I got sick of it and started to investigate. The result is that I have now fixed the issue and the laptop has been joyfully quiet - I hope it stays that way.

I believe the fan was on because one CPU core was pinned at 100%


The culprit was 'system' which when right clicked and go to propertied reveals it as ntoskrnl.exe

I also noticed that while the fans were blowing, turning wireless on/off would stop the fans and reduce the cpu usage for a little bit but not permanently.

So putting 2 and 2 together I tried updating the Killer wireless drivers with both the Dell update utility and with the driver package from the Killer wireless site. Updating the driver to the latest version ( seemed to quieten the fans for a few mins, but then they'd start up again. I also tried removing the killer control panel management software too bu that didn't work either.

In the end, I solved it by:

  • Removing all Killer software (Add remove programs)
  • Ran the Killer uninstaller utility from the website
  • Uninstalling the killer wireless device (via Device Manager)
  • Rebooting

My laptop reverted back to Killer Wireless driver provided by microsoft version and was quiet!


A subsequent windows update for the WiFi card then brought it up to version and so far has been quiet for 4 days plugged in, on battery, charging/not charging.



There's definitely something screwy with this Killer wireless. at this stage, I don't quite know if it's just a complete removal of the Killer bandwidth management crapware or the driver itself. But I'm not going to update to the latest driver version until I have a need for a hairdryer.

I have the same problem with my laptop Dell XPS 13 9380. I tried to fix it as your solution but it's quite in few minutes only.
How can I fix it or I will use Dell XPS 13 9380 to dry my hair?

I have the same problems with my laptop, too. Did you fix it? Or, did you return it? 

For some reason, the fan stops completely when I open the task manager to see what's running. It's as if it gets scared or something (like the double-slit experiment in Physics!) 

I do this once every time I restart the PC and I'm Ok for now...

Where the flip is Dell in fixing their defective implementation?  Why do I have to fight my computer ALL THE TIME?
