Right, these fans are pretty tiny. I am not confident any of the fans do very much cooling, big or small. The LED elements themselves do get quite warm in operation, and there are fanless ones for sale now that appear to have minimal heat sinks. Maybe the fans increase longevity in some incremental way. Whatever the case, the ones with large fans on the back didn't work with my pre-facelift E-codes due to the bulb retaining ring being kind of bulky and getting in the way of the heat sink element.
My experience is that for low beam the LEDs I have blow the halogens away. On high beam, they are less impressive than low beam, with a few dim spots. My low beams turn off when my high beams come on, though. Still better than halogens I think. Maybe the higher powered ones will be better? I don't think those were available when I bought mine. In Saab E-codes, the cutoff is enforced by the metal shield in the lamp housing, so I don't think you have much to worry about, with respect to blinding other drivers.
Also worth looking into is whether the high and low can stay on at the same time. A lot of these LEDs have logic preventing that. I know there's a way to wire the Saab 900 or a special relay (can't remember which) that allows our high and low beams to light up simultaneously - I don't have my Saab set up that way, so I can't speak to whether the low stays on with the high in these LEDs I have. However I do have my Honda Insight wired so low stays on when high beams are put on, but the LEDs I have in there (a different Auxito model) don't allow it, which makes the high beam pattern extra annoying, lacking near field illumination to balance out the far field spotlight.
