Inliners International Forums General Discussion Engines Temp sending unit location

Gentlemen,
Where do you recommend locating the coolant temperature gauge sending unit, in the water neck or at the side of the head? I believe the temp. at the head will likely be greater but is the head the appropriate location to measure coolant temp., for electric fan off/on settings?
Thank you.
Ken

chevy had them in both/either location. Depending on the yr. Or model.
