I have one Amilo PI 2515,received with damaged cpu fan.
I replace fan(not Fujitsu original one),and clean old thermal paste and put new AS5.
Since I encountered problems and fan was not starting (maybe because was not need,cpu is not warm too much) I take power for fan from usb so now fan is always on and at max rpm.
I leave two wires still connected to fan socket (black-gnd,yellow-rpm sensor) only red is connected to +5V from usb socket.
Problem is that always...
