Oceanis 37 engine bay fan system

Our 2012 Oceanis 37 has an impressive looking fan and ducting system in the engine bay along with her Yanmar 3YM30 engine, but this fan system is not operational and I am receiving conflicting advice on the need for this system to be operational as I try to determine what to do about it. I have one mechanical specialist advising me that this system is essential for the effectiveness of the boats cooling system - especially during long periods of motoring, or motor-sailing, whilst another specialist is advising that 'these systems are a pile of junk which never work properly, and are not essential'.

The thoughts of the forum are very welcome on whether I need to pursue a repair to restore this fan and duct system and will be much appreciated.

Kind Regards
