Has anyone replaced the radiator fan assembly on their E9x M3 with something other than the OEM part (17112283621)? The price, at over $1100 is pretty ridiculous but I am not finding much in the way of alternatives.

Following. On the same boat right now.
Getbmwparts has it for $951 though.

For a component as critical as the radiator fan, and for how long it lasts, I'd just go original BMW. Mine is still original 13 yrs and 155k kms old.

ok this was an odyssey.
The UAC part from partsgeek did not fit the M3 at all (best I can figure it is meant for a Z4).
With the OEM part out of stock everywhere, the potential workaround was follows:
1. buy the fan shroud (ecs has them)
2. buy a fan assembly for a 535i GT (though I think any fan for a N55 would do the trick
3. use the undamaged connector/electronics from my broken fan, attach it to the new fan motor from the 535i GT fan, then install all that with the correct fan shroud
This may still work but I unfortunately did not get the exact right 535i fan assembly (it was NOT OEM but by TYC) so mating the motor to the existing electronics/connector was not an option.
By luck, the right OEM fan assembly for the M3 (17112283621) had come back in stock at tcp euro for $1006.99 so I jumped on it immediately. TCP Euro offered 1 day delivery for $35 and the part did arrive the next day and I finally have a working car again.

On dirait qu'ebay a une option disponible maintenant, il l'indique correctement comme 850w au lieu de précédemment, les autres énuméraient le ventilateur N5x 600w incorrectement.

En regardant les photos, bien qu'à l'envers, il semble que la fiche soit du bon côté, car tous les ventilateurs non-m ont la prise du côté conducteur. Je pense donc que celui-ci a une chance de s'adapter si les images sont correctes.
Pour 135 $ pourrait valoir le risque si quelqu'un veut essayer.
Voici la photo d'ebay tournée pour mieux le dire.
Vous pouvez dire à la pièce UAC que RockAuto a répertorié comme étant le M3 est la mauvaise pièce parce que le connecteur est du côté conducteur comme tous les non-m, et il est également répertorié comme 600w
