I just changed the fan inside an omni interface... but it seams like there is a rpm- oder current measurement because i get a fan error message after a minute.
edit: I did some testing, its not about current measurement (tried an parallel resistor to higher the current) but the tacho signal. I reconnected the orignal fan, stopped it, and after a minute I also got the fan failure.
