So in summary Stu, the upgraded switch turns the fans on at 90 and off again at 87 WHEREAS the std switch turns the fans on at about 90 and off at about 80/81?
So in effect, in traffic, the upgraded switch will be doing more cycles but for shorter periods of time for each cycle? The std switch will do less cycles but each cycle will be far longer meaning the whole circuit becomes hotter?

And the Escort Cosworth fans are better as well if you can combine them with that upgraded switch.......

And if you can build it all onto a braided fan loom all the better? ( Where can you get the braided fan looms from? How much are they and how easy to fit? )
