- using for cooler control

is it possible to use for control fan in Turris Omnia in NAS box? Where can I connect a fan in this case (I think it is impossible to connect fan via standard cable from NAS perk because is connected directly to 12V - fan is still on)?

You can connect a fan from the end of the power cable that comes with the NAS box. But I’m not sure about controlling its speed though. I hope someone can provide a solution because I’m going to have to disconnect mine for now because of the noise.

Yes, but it is exactly what I don’t want, because in this case fan will run nonstop.
In this case is needless.
