Is it necessary to replace the fan clutch motor when replacing the water pump or is the service department trying to rip me off

I THINK SO,THE BOOK READS IF NOT MISTAKEING YOUR SUPPOSE TO CHANGE THE FAN CLUTCH EVERY 30.000 MILES,IF YOU GOT HIGH MILIAGE MAKE EASY ON YOUSELF WHILE YOU GOT FAN OFF TO REPLACE THE FAN CLUTCH.OLD SAYING PAY ME NOW OR PAY ME LATER
I have many regular clients with over 100K miles in their BMWs with the original fan clutch and they are working perfectly fine. Some had a replacement water pump - since I don't like and don't trust pumps with plastic impellers, so they were replaced by one with metal ones, but still uses the original fan clutch.
I have seen failed clutches at 60-70 K, sometimes even at lower miles, but there is no regular replacement interval for those.
I have several BMW factory repair manual - I don't think I ever read about a 30K replacement interval, but I''ll check them tomorrow when I'll be at the shop.
