CPU Fan doesn't spin on sartup

[XRone99]

Describe the bug Very often on system startup CPU fan doesn't spin even if the program says it's spinning at some RPM

To Reproduce Steps to reproduce the behavior:

1. Start the system
2. AlienFX GUI starts itself with windows on tray
3. I see cpu temperature slowly rise and fan doesn't fisically spin even if the program shows some RPMs
4. If i restart AlienFX GUI or change "Power Mode" from manual to any other value and the go back to manual everything works perfectly

Expected behavior AlienFX GUI should be able to control CPU fan without the need from me to restart it or force the cange of Power Mode

System (please complete the following information):

• Model: Alienware X17 R2
• Model details: i7-12700H, RTX 3080Ti Laptop, 16GB RAM
• OS: Windows 11 Home 22H2

Additional context I use a custom fan curve and it works perfectly fine if I do that thing to make AlienFX get unstuck

Oh no, not again!

We are solved this issue for a couple of other systems, seems like BIOS/SPI broken after some update. Did you update BIOS recently?

I can add your system to force list, but i need to know your SystemID. Run alienfan-cli rpm from the Administrator CMD and share me the output.

Last time I did update BIOS was far before the last update of AlienFX-Tools, this issue appeared just with the last update

This is the output:

But I have to specify that in this particular moment fans are working as expected (as I said it doesn't happen everytime, only on some computer starts)

Ok, so your SystemID is 4800.

Looks strange, i don't change anything into fan control last releases... This looks like the bug into Manual profile control into BIOS, so they miss PASV point... Yes, switching mode helps.

Try this one - it should help - fan_gui.zip

[XRone99]

Ok, I've been using this version you gave me for some days with no problems BUT as I said the problem already was intermittent In fact this morning it happened again, as always switching mode and going back to manual helped the fan start spinning correctly as always

[T-Troll]

I do some into latest release version. If this didn't help again, seems like issue into BIOS, and you should configure out the system other way - i tell you how.

[XRone99]

So I should download the latest version? (By the way in the last 2 weeks or so fans have worked fine)

[T-Troll]

It has some other fixes about it, so try.

[XRone99]

Thank you, i'll try it and let you know <3

I've tested latest version for some days and I can tell that the problem is still there; as always it is discontinuous, sometimes it works, sometimes fans are blocked on 700rpm (sometimes is CPU1, other times is CPU2 or GPU 1 and so on; it seems to be random) As always changing between profiles does work and restores function

[T-Troll]

Hmm....

Latest version ALWAYS switch between power modes then resume from sleep. So i really don't understand how it is possible to still hang fans. Maybe timing is an issue....

[XRone99]

Today I've noticed something: It's NOT that the program doesn't control the fan spinning, actually it does The thing is that Fan Max RPMs are lower then actual maximum until I change Power Mode to another profile and then switch back to Manual For example CPU1 fan will spin at 4000 RPMs on manual mode 100% boost BUT if I switch to another profile and then go back to manual it will spin at 5300 RPMs And I can tell this difference matters in terms of temperatures (and also is audible even without looking at RPMs)

I wish this could be helpful

Oh... Look at this - https://www.reddit.com/r/Alienware/comments/147sckl/fan_speed_not_working/

Seems like something broken into BIOS for some models...

About you issue... All i can do is delay power mode switch - MAYBE this can help. Now i switch mode to Balanced then app start/resume, then switch to mode you define into profile. But now it will be done immediately, so i have an idea some delay between can help.
