What is interesting is that the heat-generating monster M5 F10 has no front radiator fan for the AC and only a rear electric radiator.

Here another information of the upgraded fan of the Z4 35is and 1M.

I think I will remove completely the fan clutch and the AC fan from my car.
I start to think that the AC fan and case is reducing the air flow.
Otherwise I cannot explain why BMW ditched it from the M5 F10 which is the most challenging car they ever built in terms of heat management.

I found a CSL without AC and in front of the radiator there is nothing blocking the air (like in my M5).
I will get back later with some pics of my DIY.
