--- Comment #2 from Martin Peres <[email protected]> --- Hi Marcel, I was expecting to get a bug report on that much sooner. I will need to dive in the vbios tables again to fix this. The way fan speed is calculated is by reading the number of impulsions sent by the hw tachometer. The tachometer has 1/2/4 or 8 pulses per turn. I couldn't find information in the vbios as for how many pulses per turn I should expect. I made it to work for all my cards (the same value worked everywhere) and thought maybe NVIDIA forced manufacturers to use fans with the right number of pulses per rotation (although it was weird). Could you extract your vbios[0] and attach it to this bug report? It will help me in my quest to find the byte I'm looking for! Thanks!
