    I have an almost 5 years old Vortex III elite with crossfire 7907ms. One of them died (the one from the main slot) so I swapped the other one on the main slot. All good but the problem is that even if I'm not doing much, the fan from the empty slot kick is and just runs in loops (starts, stops, starts etc.; you can hear it). Also I have noticed that it mostly kicks in when I play a video or a movie and the GPU temp just locks in at 69 degrees for some reason, voltage at 1.0V from 0.82. (I'm not overclocking or anything).

    Now I did try to disconnect the problematic fan but after doing that, the laptop shuts down by itself after a few minutes.. I am running it on power saver with everything turned down manually including processor state.. If I put it on high performance it jumps to 79 degrees in idle :| And this is happening since I removed the dead card. The fan that is actually connected to the running GPU is blowing hot air but the other one that doesn't have the secondary GPU attached anymore is blowing cold air like crazy, and making a constant revving sound. Like I said, I tried to disconnect it since there are already two fans in there (cPU and main GPU) but the system shuts down after a few minutes as if it would get too hot. What the hell?! Than why is it blowing just cold air. I just can't make sens of it. If I could joke about it I would say the laptop is feeling phantom pain from losing one GPU

    What should I do? Or at least, what seems to be the problem? I have tried with latest drivers as well, used DDU, same story. I just want it to not go to 1.00 V for no reason and start that annoying looping sound.

    Thanks

    Perhaps that slave-now-primary card isn't an original Clevo? Temperature-report was a bit of hit-and-miss for some of the non-Clevos.

    Regardless of that, you could disconnect/clip the red+black wires on the slave gpu fan and tap the blue one into the blue wire of the primary. That will keep the system happy as the slave gpu fan will receive the tachyo-report from the primary gpu fan (preventing the auto-shutdown) and also keep the slave gpu fan from spinning (since it can no longer receive power).

    Cmos reset or re-flashing the bios may also work to get the system to finally realize it's no longer running CF.
