Has anyone else gotten a Corsair water cooler and noticed is smells horrible out of the box? It smells like hot rotting fish out in the sun. It's really bad.
Could be an issue with the rubber or (less likely) plastic parts. If it's really unbearable try taking it back and exchanging for one from a different batch.
I have a H110i GTX on my secondary rig, and it doesn't really have a smell at all, of any kind, so I'm not sure what to tell you, lol. I suppose if it's bad enough, just return it, as Quixit suggested.
