But this menu was removed from newer laptops, so taking control over the fans was not an easy task. Back in times, on Dell Precision M6500 and older there was a keys combination that could bring up EC menu where you could turn thermal management off. The only way to be able to control fans with software is to turn EC thermal management (tm)feature off. HWinfo64 and SpeedFan have such an option, but in most cases setting up custom fan speed resulting in fight between EC and the program - EC sets its own values for fan prior to program values. The only way to control fans is over SMM. The thing is, that Dell on most of their laptops don't allow controlling fans via Embedded Controller (EC) as Notebook Fan Control utility do. Part I: IntroductionHi there!I was curios about fan control problem on Dell laptops for some time.
