I recently bought a 16 inch fan and have worked out how to wire it up so that it the new fan logic resembles the below table.
Temperature less than 91ºC and AC Switch Off
No fans on
Temperature less than 91ºC and AC Switch On
AC Aux fan on
Temperature between 91ºC and 99ºC
Spal Fan on
Temperature above 99ºC
Both fans on
I see most people mount these fans directly to the radiator. However, I don't want to poke the zip tie things through my fins. I also think it limits how well the fan actually draws air through the radiator.
The shroud will be cut/potentially laser cut out of a sheet of aluminium.
The Spal fan will mount directly to the shroud using Spal's provided hardware.
The shroud will bolt up to the 4 holes at the top and bottom of the M42 radiator, which will make it stand off the fins by a few mm, which should make the fan much more efficient, and probably look quite good in the engine bay.
Just wanted to throw this idea up here.
If anyone is interested in one for their M42 PM me.
I'm in Australia, so it is probably cost prohibitive for me to make them and ship them to the US, but we'll see.
