I have three, one in my '73 F100, one in my '66 Mustang, and one in my '75 Duster. Never have had a cooling problem and they are quite a bit quieter than a wobbly clutch fan
That has been my experience, noisy, and seem to redure air movemnet when at high rpm and the blades are flattened out. Whent back to the clutch fan. Been extra successful with dual electric spal fans on my street rod with a griffin rad. Ed ke6bnl
