Old condenser fan OK with new compressor?

12 year old unit, just had compressor replaced. Condenser fan is original, but works fine. Is there a big risk in continuing to use the condenser fan until it goes out?

If the fan stops, the thermal overload will trip and stop the compressor from burning up. But does it still overheat enough to significantly reduce the life of the compressor?

Thanks for your help.

depends on the condition of the fan.. I have seen the rivets break / work loose causing the blades to eat up the condenser coils.. This would be bad just after a new comp. install

If it stops, the compressor may start blowing its internal relief valve. That sounds like a shotgun blast and can harm the compressor.
