That's good to hear
By redundancy I meant a backup to the factory aux fan not a second aftermarket one. I was a bit worried because the aux fan does eventually give out, but I have replaced mine not that long ago so maybe overkill. That being said, I can't remember for sure but I don't think I ever replaced the electric fan in my wife's X3, I should probably look into that before summer or maybe keep an eye out for a cyber week deal!
