I've once experienced similar problem with my E92 335i. It got so hot till the point the car refused to move forward to prevent any engine damage. Got it towed to BMW Seattle, turned out that some foreign object got stuck in the fan, preventing it to rotate. They removed the object and the car ran well after that. Hope this helps.
