I would not be surprised if a few of the cooling problems with the older cars is due to the lack of a shroud around the fan?
I worked on R&D for an air compressor manufacturer back in the ‘80’s and we were developing a 2 stage compressor and using a radiator for the intercooler. Without a shroud only the area of the fan was proven to draw air current through the rad, with a shroud the whole radiator was utilised.

Agree with Primaz, the Mk2 engine bay is a great heat sink, there are no vents taking cold air in or hot air out, and most of the cold air flows directly under the car.
The Mk2 came with a shroud, and it does make a significant difference, but a good electric fan will shift a lot more air than the original fan ever could, so a good high CFM electric fan without a shroud is still better than the existing fan with the shroud.
