My (very) uneducated response would be it's normal to get pretty warm to the touch.
Is the concern here reliability/service-life or performance/efficiency? My X2 motor gets warm but not warm enough to cause harm. Certainly not nearly as warm as most of the electrical items underneath the hood of a car. The alternator on my Neon sits very near the exhaust manifold but still held together for 160,000 km. The stock X2 motor does have a good size fan at the front end.
At what point does heat start reducing performance? Thinking of the car example, a hot starter is less efficient. Of course a starter isn't in continuous duty, so maybe a bad example.
Anyone who says "It only goes together one way" has no imagination.
