Discovery 1 V8 - noisy cooling fan. Normal?

[Plinth]

Hi

Last month I had a new viscous fan unit (fan clutch?) fitted to my 1997 V8 Disco.
According to what I have read, it is functioning correctly, but the fan blades are so noisy when it is “engaged”.
The whooshing noise drowns out the engine – even with tubular manifolds and a sports exhaust.
Can I fit a quieter fan? (Less blades should be less noise…)
Should I junk it and change to an electric set up?

Cheers

I think I might take up your idea of fitting an electric fan.
I have been driving the Disco for 14 years and I don't recall hearing the viscous fan, even at start up, until the last month, which prompted me having a new unit fitted.
It would seem that it was not working during all those years - and the engine never got hot, so perhaps even the V8 is well cooled...
