Fins enhance convective cooling and you want to equalize cooling as much as possible around the cylinder and especially closer to the combustion chamber.
On the top the fan blows directly onto the cylinders to equalize the cooling effect they enhanced the cooling on the bottom and top vis differentially sized fins, turbo also used a higher temp alloy than on n/a, RR530 wasn't used on n/a until the 993 series
3.2 n/a used the higher fan speed too
