Many threads with exactly the same problem:

No solution.

It's annoying how careless Dell is about this matter but basically my Dell XPS 15 turns fan on and off in 1 second, forever. Support says that Nvidia drivers are checking for temperature and therefore they have to enable a fan for a split of a second.

What I did so far:

  • Updated BIOS
  • Updated all Nvidia Drivers
  • Updated all Intel Drivers
  • Installed many Nvidia utilities

Nothing helped. Does anyone occur to know why a laptop may be turning its fan on and off all the time?

It's because of the rampant failure of those chipsets:

Because they fail when overheated and cooled, they updated the BIOS to go nutso on the fan.

They changed it in the BIOS and I'm sure they didn't take it back out. The only way I could conceive to eliminate it is to downgrade the BIOS to before they did it. I admit I'm not sure this is possible.

I have an M1530 and I'm running A12 dated 11/19/2008. I'm pretty sure that was the last one to not do it.

Thanks for an answer! I bought my computer on eBay in 2011 or 2012 soon after it came out. No BIOS older than 2011 is available. Can anything else be done? I don't play any games so perhaps disabling a GPU can help? Is this possible? –  Paul Mar 13 '13 at 7:27
    
Oops, a little research reveals that A11 was when they turned it on, and it looks like Dell has disabled all the old BIOS-es. Perhaps aftermarket fan control, like MSI Afterburner: event.msi.com/vga/afterburner/download.htm ? –  LilCodger Mar 13 '13 at 13:42
