IMHO removing the viscous fan is a mistake, it keeps a steady flow of air over the engine and prevents the thermal shock of an electric fan cycling on and off. IMHO many cases of fuel vaporisation are caused by fan removal. No doubt others will disagree.

I think the viscous fan helps keep under bonnet temps down.
When I bought her she only has a big kenlowe, however it didn't take long for me to fit the viscous fan back on, couldn't cope with the swinging temperature gauge!Mike.

And if you read the technical bulletin that details the tests done some years ago, the viscous fan was a massive part of the reason well maintained engines stay cool. Stuck in traffic temp gauge creeping up? More revs (to about 1500) simples.
Mine came minus VC, has one nowPaul - 3 projects, 1 breaker - garage built and housing 2 white Stags. One runs, one doesn't
