Agree with Stuart, Bob. Lower range rather than higher. I've no experience of an electric fan on a Seven but I have with a Meadows 4ED in a 12/40 Lea Francis. That car has no fan and no water pump as standard so thermo-syphon is all there is. An electric fan wouldn't cool the engine down once it started to overheat. However, turning it on when I could see a situation coming where it would overheat stopped that happening. The best example when I had the car was approaching Le Mans on a busy, hot, late afternoon, one September. I could see the traffic building up and overheating was sure to follow. Turning the electric fan on before any overheating started and leaving it running solved that and we arrived at our hotel without issue despite miles of stop/start traffic.
