Here is the GUI of the utility.īasically, it can monitor/set your fans speeds and disable EC control. And since I have AMD GPU on it, my laptop can't adjust fan speeds based on it's temps - EC is basically reads temps from Intel GPU chip instead of AMD (and most interesting part is that Intel GPU turned off). But overall, there are all binaries on my hands and they are working perfectly on my Precision M4600. A bit time later, the Dev contacted with me and kindly shared his precompiled binaries. After day of waiting, I've decided to compile it by myself and yeah, I spent reasonable amount of time till I got final 'product' - but it's totally worth it. But the problem is - there is no compiled binaries, only source code.įirst thing I did, found his email in contribution log and asked him to share final binaries, because I'm not kind of man who is into compiling under Windows. Looking through his repos I was kindly surprised also to find which is using this driver. Lucky Linux users found out some time ago a method to disable EC tm via i8k driver and SMM commands and control the fans with i8kutils.Googling a lot for Windows solution showed no usable results until I found someone on GitHub who developed a. 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.
