keyword=TO: In emergency situation when target warmed up, you need to reduce fan speed.

The instruction to not change fan speed is for normal operation. In emegency situation of target warmed up (due to vauum failure, ESR crash etc.), you need to cut all heat load, including reduce
the heat load from the fan. In this case you should change the fan speed down to 10% (24 Hz).
