Anyone use these electric fans?
IMHO
That shroud will be blocking a large amount of air at speeds above 30mph
All the area in read being parallel to the radiator and in close proximity blocks air flow resulting in overheating at driving speeds.
Another thing to consider...
The size of the engine those fans are designed to cool. 1.5, 2.0, 3.5L engine???
You are most likely trying to cool an engine twice the size.
Look at what the cooling is for a 2023 Challenger with V8 that is what you should be trying to achieve.
Will those fans work, maybe. But if you search "my engine overheats" you will see some very common threads.
I'm am not anti electric fan, but it and the rest of the cooling SYSTEM have to work together
Good luck to you.
