thanks for developing great tool!

version3.0 works fine on my laptop(Ryzen 5625U), but I can't restore factory default thermal settings.

I tried hard reset(disconnect AC > remove battery > hold power button for 20 seconds).

Is there any way to restore default thermal setting? or “Optimized” is factory default one?

 

"Optimized" is factory default.

Thank you for your reply! Then, I should select “Automatic” - “Optimized” for factory default settings, right?

Yes. The same options are available in the “Dell Power Manager” app, and in the BIOS setup on some models. (My names for each mode might be a little bit abbreviated.)

There is currently a bug with the privilege check if you have UAC disabled on your system.  The program needs to be run with UAC enabled.

Atualmente, existe um bug com a verificação de privilégio se você tiver o UAC desativado em seu sistema. O programa precisa ser executado com o UAC ativado.

Unfortunately it still didn't work!

Is there any new updated download link? The available links are download off.

I want to test this on my Dell Inspiron 7720 SE.

Hi guys, 

 

Good to meet you! I tried the Dell Fan Management software (command line and GUI versions) and even though in the GUI version the fan RPMs report correctly, all controls are disabled and I cannot control them.

 

Possibly this is because I have a 2023 Dell XPS 15 with 13th-gen cpu, i9-13900H.

 

Is there any direction I can go to which will let me enable the fans always to 100% to your current knowledge?

 

Thanks

[Aaron44126]

No.  There is currently no way to manually manipulate the fans in 12th gen and later systems.

hello, friends. 
Im using DELL Latitude e6230 machine. 

 

at this moment Im using DELL Fan Management on manual mode , FAN 1 set to OFF.

 

This works, but Im not very pleased that I need every time manually switch the fan speed depending on my current work task.

globally, my main question is : any solutions how can I make it work automatically ? 

 

I tried to do some things with Consistency Mode, but I failed to understand how it works.

Also, following the Manual on GitHub involving SpeedFan, and I tried to create the point when the fans should start work harder, but SpeedFan refused to produce any result, it didnt react to my "scale of fan speed"

can you please share any help? 

 

p.s. actually I think I would be satisfied with "Quiet" mode on thermal Management, but it is greyed out. Is it possible to make it available to work?

[Aaron44126]

I wrote consistency mode to try to "lock" the fans at the minimum level (other than "off") that the EC will normally set them to.  I found this to be lower than the level you get when manually setting the "low" speed.  It will also automatically "unlock" them and let the fans ramp up if the temperature gets too hot.  You want to set the RPM threshold slightly higher than your target speed, and the temperature threshold to where you want the fans to become locked and unlocked.  If the system has not locked the fans, it will indicate why in the status bar.

 

The Cool/Quiet/Performance modes are just using the same modes offered in Dell Power Manager.  It is only supported in newer Dell systems (2015 and newer I think?).

 

I'm not updating this program anymore.  My personal PC is a Mac (zero fan issues) and my work PC is too new to support any type of manual fan control, so I literally have nothing to work on it from.

thank you very much for your reply. 

So, lets say I want fans to work quiet,  and only start work on full power at 80C. 
so, I set RPM treshhold 1000, Lower Temp tresh 70, Upper Temp Tresh 80.

But my current Temp is 55C, and RPM is 3000, and all I get, is just info sayin "waiting for emmbeded controller to reduce the fan speed"
 

but it should already automatically slow the fans, doesnt it? how can I improve my scenario?

thanks !

You have to wait for the EC to "automatically" lower the fan speed below your threshold.  1000 is too low.  The lowest speed that the EC will run the fans at before turning them off varies by system but it is probably in the 1400-1800 range.  You'll want to watch the behavior and see what a typical "low" speed for your system is and then set the threshold a little bit higher than that.

 

(If your system runs the fans at 3000 even under low load then this will probably not work out for you.)

 

You can try turning off CPU turbo boost to lower temperatures and fan speeds.  I have an article about options to toggle that on and off quickly in my sig.

thanks again for your reply. 
in my case Turbo boost is already disabled in BIOS, I did it because with TB enabled the laptop randomly blows up the fans for no reason. 

so, I have 3 modes avaliable : 0. 3000. 4900. those modes respectively match the same settings from manual mode (off, medium, high).

my question is : is it possible to set up fans to keep at 0 RPM until 60 C, spin normal from 60 C until 75 C, and start full at 75 C using Dell Fan Manager  ? consistency mode for example ? 

p.s. I checked the manual involving SpeedFan but SpeedFan doesnt react to any changes I do, even despite [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CI\Policy]"UpgradedSystem"=dword:00000000 is created and DellFanCmd is installed

[Aaron44126]

You can do that with SpeedFan. For SpeedFan to work, you need to enable Dell fan support in its settings, and you need to force automatic EC fan control off using Dell Fan Management (manual mode, EC fan control disabled) or DellFanCmd.

Hello, @Aaron44126 thank you for your reply.
I have a following question : can you please suggest how to use DellFanCmd? I mean, according to the manual there sould be some commands -enable -disable 

DellFanCmd.exe ec-disable

but when I click on the file (downloaded from github) just nothing happens, it doesnt launch any window, it doesnt give any sign of doing anything. 
I may confirm my system supports it because Dell Fan Management tool works.

Im asking for it because unfortunatelly SpeedFan doesnt work properly with those settings. I tried to set up with "control automatically" both enabled and disabled but it doesnt correspond to the RPM/Temperature graph I created. 
I checked your manual here and followed the instructions given, but unfortunatelly it was not indicated if automatic Mode should be enabled or disabled. 
i mean this mode

You have to use a command prompt (running "as administrator") to enter these commands for DellFanCmd.  It is not a GUI application so it won't do anything if you just click on it.

 

You can test if SpeedFan can control the fans properly by just manually setting the PWM in the main window.  It should react differently if you set it to 0, 50, or 100.  (It will not allow for more granular control of the fans than that, it is limited to the same three speeds as my app.)  Automatic EC fan control does have to be disabled in order for SpeedFan to be able to do anything, and also you must activate a checkbox setting in SpeedFan configuration that says something about supporting Dell fans.

greetings, @Aaron44126
today I faced this problem 
Dell Fan Management app failed to open, instead I got this message

no updates or software modify were made in last visible term

the only problem I had experienced during the period of using the app was a fact that after un-sllep the laptop -  app required a re-boot to work again
but this thing is totally smth new

I tried to install .NET 4 but it says I already have this 

Microsoft .NET Framework 4 is already a part of this operating system.  You do not need to install the .NET Framework 4 redistributable. <A HREF="http://go.microsoft.com/fwlink/?LinkId=164207">More information</A>. 
 
could you please suggest if it is possible to be fixed ? 


UPD

I managed to resolved the issue. After googling some lines from the Error I found a forum from 2008, there s a guy advised to update Visual C++ Redistributable. For some reason this worked.
So, the issue is gone, and I leave this message to someone who may also meet this problem and for @Aaron44126to be aware of this also.

but this doesnt explain why this happened, and why original VC++ got erased or deleted, how this whole situation happened I still have no idea

Alright.  I use Open Hardware Monitor for reading the CPU temperature, but the GPU temperature uses NVAPI directly, if you have an NVIDIA GPU.  (Actually, I'm using a fork called Libre Hardware Monitor.)  They would need to fix this and then I could incorporate a newer version of their library.

 

Try this new dev build.

https://1drv.ms/u/s!AsIwJHFk4EFdqNc2I45BxBqHhwaKIA

Needs .NET 6 if you do not have it -- https://dotnet.microsoft.com/en-us/download/dotnet/6.0 (grab the "desktop runtime").

 

Before launching it, go to regedit, navigate to HKCU\SOFTWARE\Dell Fan Management, add a "DWORD" value named "DisableCpuTemperatures" and set it to 1.  That will disable CPU temperature reading in Dell Fan Management and hopefully work around this stutter.  ("Consistency mode" won't work properly with this setup because it needs to be able to see the CPU core temperatures.)

 

It could be a Windows 11 issue?  I have done very little testing on Windows 11.  I'm not running it on any systems right now.

Been a while but do you think you'd be able to drop a version with NVAPI disabled completely? Don't really need graphics temperature monitoring anyway, just fan control

[MELOCODI]

I have installed a newer version of .NET and now I get this message.

  

[MELOCODI]

nvm, .NET 5.0 just decided to die, I fixed it lol

[Shahin]

I come with some testing and i have a lot of info.

Precision 3581 - 13gen i7 13800h with single fan.

When i run cmd command to test EC i get: 

while no fan is spinning.

 

i tried: DellFanCmd.exe ec-disable-alt and without -alt. nothing changed. I try fan1-level2 or 1, nothing happens.

Then i try to build the latest DellFanManagement, and i get No EC fan control, only Consistency and it just bumps up and down around my threshold using about 25% of my cpu, spiking 100c on different performance threads randomly.

And i can't use EC fan control on manual to set a constant fan utilisation. Neither the fan percentage.

 

(latest bios for my precision 3581, clean windows 11 install, all c++ runtimes and .net frameworks, also power mode on balanced in windows, but the bios is on High performance)

 

Also, DellFanKeepAlive doesn't open, and DellSetThermalSetting doesn't open. 

 

PS. Dell Power Management is no longer in the microsoft store. it was moved in Dell Optimizer and it looks like this: 

and it can be downloaded from official Dell Driver support page

As stated above, this only works with 10th-gen (2020) systems and earlier. Dell has changed how fan control works and 11th-gen (2021) systems and later cannot be manipulated at this time, by any software that I know of.

Frist of all, thank you for the interesting report. The fans drive me crazy and it's good to know, that I am not alone. I have already renewed the thermal paste. The fans are off when Windows is idle now.

I am using Dell Fan Management and have the following questions:

1. when I start my 3 years old Dell Inspiron 7590 the fans are running after a few minutes, but when I start Dell Fan Management in Automatic operation mode, they stop for a while. What does Dell Fan Management change?

2. Using Dell Power Manager (or Dell Fan Management), the thermal settings won't match. Quiet and Performance thermal setting seems to be same, and the fans are spinning at max.

 

The best (silent) mode for me is EC fan control off, manual and medium ( ~ 2.200 rpm). The temperature is around 50°C.
