This is now so annoying that I want to take controll from EC. I did following:

1. put to command prompt:bcdedit /set nointegritychecks off (I also tried with bcdedit.exe -set TESTSIGNING ON)
2. re-booted.
3. I run Dell fan utility from here: https://onedrive.live.com/?authkey=!ANfN72eDdyf7EVg&id=72316AA2942F0A8A!167998&cid=72316AA2942F0A8A

4. I disable EC



Only problem is that this program does not disable the EC so I can not adjust the fan settings with HWinfo. Any idea what I have done wrong?

 

I also tried this by downloading your DellFanCmd-master folder.



If I now type that "DellFanCmd.exe ec-disable" it does not understand the whole command. I know I am complete idiot what it comes to Powershell and these programming things.

I would really prefer an option I could take controll of fans without rebooting the machine. I sShutdown this laptop always and when I turn this on again I would prefer the option I can take controll of fans without rebooting the machine after that. If I understood right the Dell Fan Utility did not need rebooting after the driver signature check was off by command:"bcdedit /set nointegritychecks off".



At least the "nointegritychecks is is satus no, so I think this should work. How ever now the problem really is that I can not take controll for fans no matter what I try.

 

Use "Command prompt" and not "PowerShell" and it will be easier to use. In PowerShell you have to prefix with ".\" to get it to run a program from the current folder.

If you make any changes with bcdedit you MUST reboot for them to apply. bcdedit adjusts the boot-time configuration. However, you do not need to disable signature checks to use this program. The thread linked explains the registry setup needed to avoid this.

 

I finally managed to take controll of fans. I do not know what I made wrong earlier though.

I wanted to get these fans controlled now with Fanspeed program. I was not very surprised that even this did no go smoothly. I have tried now several hours to get this working but no idea why example with these settings below the cpu fan is running 100%. Do you have any idea why this is happening? Now it is actually even worst than earlier because fans kick in about 50C then fans go 100% state but they stop after 3 seconds and the same cycle starts again.Dell info is enabled in options also. I know hysteresis should be added there also but now it does not affect to fans behaviour.

Manually I can adjust the fans from Pwm1 buttons but nothing adjusted pre-settings does not work.

I compared the temperatures to Speccy temps and end up that I should monitor CPU temps by "CPU-CPU from Dell@03E8-option because those temps seems to match tems I have in Speccy program.

GPU temps seems to match to Temp6-option.

I would really appreciate if you can tell me if you easily see some stupid mistakes I have made here.

 

The problem was that there was 50 degrees as default warning temps for CPU and GPU. After that I think speedfan just puts fans 100% state.

Well I finally managed to controll fans with Speedfan by increasing the warning temps but I can not really trust the system. It seems that at least from hibernation wake up I end up the situation there was nothing controlling my fans anymore.

This might be good tool for special times when the CPU load is optimal for annoying 3 seconds cooling cycles with EC.

How ever in those occasions I should be easily be able to switch EC back again but that is now something I am not able to do.

Also I am a bit worried does it affect security if I am always using Test Mode in order to get fan controll from EC.

At this point I would be interested to hear is this annoying cooling cycle issue really came with BIOS updates so could there be older BIOS I should try to get reasonable cooling policy?
