Does using a custom fan curve damage the fans ?

I have a NVIDIA rtx 2080ti and set a custom curve to get approx 60C at 100% usage, it's not very exaggerated, but will it damage my fans at long-term?

No, it’ll be fine. 
 

Better question is, why do that? PC parts don’t mind running a bit warm, and maxing fans out just makes then loud… you can just let the GPU manage it’s fan on auto, it’ll be fine 🙂

No reason to, it will wear out the fans faster if they are spinning more, and it will be louder. As @LIGISTXsaid.

Fans are rated to run at their maximum RPM 24/7, that's how they measure their longevity.

 

You'd have no issue running them at an increased speed.

 

You wouldn't start to see a noticeable/problematic degradation in the fans until the card is long past obsolete anyways.

 

ALTHOUGH, you may be better off setting a fixed RPM. Sudden ramping up and stopping wears out a fan faster than just letting it run 24/7.

 

Fans changing RPM is also far more noticeable than a fan sitting at fixed speed and noise-level.
