Well now you either have to go through Corsair and RMA the fan, or spend about 15 bucks to get a new 200mm fan.
Corsair is usually pretty decent about these things, email their support and detail how the included LED side fan doesn't work and how you've tried it with various different fan headers. They may just send you another and if not, it doesn't cost to ask them first before forking a few bucks over to someone else for a aftermarket fan.
