Fan question (UPDATE: Nevermind keep scrolling lol)

The 5 blade fan should move more air due to the weird design and the viscous is the fluid in the clutch unit. They should be used together.

The fan diameter should fit the shroud being used.
Thanks. So the car did not have a fan clutch or a shroud, and I am not inclined to put a clutch on it, so I am probably going to ditch the 5 blade fan. I did realize that I can adapt the old 6 blade, so I think I'm going to paint it and give it a try. I also ordered a shroud.
