Windows 11 Framework 16 I recently took out my GPU to clean one of the fans. However, now I am getting a “Fans not detected” on boot and my laptop doesn’t spin them up under load. The GPU is able to be utilized fine, but for some reason the fans just aren’t detected. I don’t think it’s a connection…

The fans are detected by the EC. The connection between the EC and the Fans is over the “interposer”. The small connector between the mainboard and the expansion bay. It would probably be a good idea to open up the laptop, remove the interposer, and check that it is clean and no dust or something …

I did that and still the same problem :(. So the interposer appears to be just fine. And attempting to force the fans on did not work, they did not start at all.

Can you get any log output from “ectool console” while trying to force the fans on and see their RPM. It might give some indication as to why the fans are not working.

I should’ve clarified: I’m on windows so I’m using Framework Control to try force my fans on.

Yes and I didn’t find any help from it

Point being that this appears to be an issue with the Framework 16 AMD laptops (which model do you have?). One thing to try appears to be seeing if the issue occurs with the mid-plate removed (as noted by two people in the 7040 Github thread. See the Github issues in links below and add your exper…

Update: I’ve contacted support to see what they have to say and I’m fairly sure at this point it’s a hardware issue, as I tried downgrading my BIOS to see if that helped at all and it didn’t. And since the interposer is seemingly working fine (as I can use the dgpu), and the fan cables have no visi…

Yeah I think my issue is most likely a hardware one as my fans aren’t even working within the OS
