AW18 980m SLI second fan solution ?

So let me get this straight. I have to flash the VBios from the right card to the left card?

 

If it makes it easier, just flash the vBIOS I posted to both cards.

 

Now I flashed your linked VBios. Every Dell non Gsync and every Alienware non Gsync VBios.
No change, the fan also stays still.

 

Have you tried swapping the fans, to rule out that everything is OK with the fan?

 

With hwinfo64 the fan is spinning

 

The curious thing is, I bought this AW18 2 years ago from TheDantee with a broken Mainboard and no GPU‘s. And it was sold Original from Dell with 980M SLI.

 

EC could also be faulty, Alienware 18 is such a poor platform to work with its not even worth messing with. I would dump that machine and get a M18x R2 if you want something Alienware, or some newer clevo machine.

 

I only want to get it working to sell it.

 

One hack-ish way to make it work is to split the pwm signal wire from the working fan and connect it to the non working fan, but keep the other 3 wires connected in the header, that would make both fans work at the same RPM, but still be powered independently and still report RPM to the system as well.

 

Yes I know. But that’s to hackish.
Anyone tried A14 Bios with 980M sli?
