Aftermarket actually makes some decent complete fan assemblies (includes both motors, fans, and shrouds in a single assembly) - they work well, last a long time, good prices. If one of your fans is out, the other is probably not far behind.
Ebay is a good source. Not sure if sources in Spain/EU, or what shipping would be if not. One design for all engine applications.
Are the wiring and relays to the fan motor good? Is it getting voltage? Or is the problem mechanical (wobble or worn bearings or other binding)? No use replacing fan assembly if the problem is outside the fan assembly.
