Alright, joking aside, I ended up installing a high speed oil cooler fan, as well as an additional oil cooler with separate pump. The pump draws oil from the front of the oil pan and returns cooled oil to the rear of the pan. In the middle we installed a baffle, just in front of the engine oil pump inlet. The benefit of this system is that it does not influence the oil pressure, and also ensures that the sump is wetter where oil is needed for the engine oil pump. The drawbacks are that it needs to be turned on manually when needed (both the pump and fan), and that my horn now sounds terrible haha. Because we installed the additional oil cooler on the drivers side.

I have posted pictures in my build thread on spo olstreet under the Z4 section.
