Summary0002396: Fans won't change their speed / SpeedFan doesn't start with Windows

I installed lately Windows 8.1 on my PC and tried now to configure SpeedFan as I had it on Windows 7 (same computer). Unfortunately, I'm not able at all to change the speed of the fans - neither manually nor automatically. If I type in a new percentage number, the fans don't react at all. In addition, the start of SpeedFan has to be done by hand.

Thanks for help in advance!

EDIT: Works now, forgot to set the PWM-Fans to "software-controlled". Autostart is still not working, even with task scheduling.

Finally I've figured out how it works for me:

1. Open Notepad and paste the following code:

@Echo off

set __COMPAT_LAYER=RunAsInvoker
start "" "C:\Program Files (x86)\SpeedFan\speedfan.exe"


2. Save file as .bat
3. Open Notepad and paste the following Code:

WScript.sleep 5000
WScript.CreateObject( "WScript.Shell" ).Run "PATH TO BATCH-FILE",0,0

4. Save file as .vbs
5. Copy the VBS-file to the autostart-folder

Have fun with it.
