How do you get ride of ice on the fan if there is any?
You may find the answer counter intuitive.
Depends on how/when it got there
If it was inflight the signatures are vibration and there are published procedures for spooling up the engine to centrifuge it 0ff.
If it is there in walk-arrounds then call a mechanic and he may remove it with a heat source.
Just remember that if you use spoolups, they have to be high enough to actually dislodge the ice and they have to be often enough that the shed itself is small and won't damage the engine when it bounces off the cases
