Has anyone used the crossbars from ROCKAUTOACCS? I like its style but got some noise concerns while drive faster above 80.

 

Sorry missed the link as a reference:

 

wind noise mostly is caused by installation position of the crossbar at the front.

Here are a few tips to get it improved:

1. Adjust the bracket position back or forward a bit to get the bar tilted.

2. ChecKing the brackets around area to avoid some gaps or improper positioning brackets.
3. Use a string to wrapt the front bar at 45 degree to test of the noise comes from the top surface. If wind noise is reduced significantly, then applying a striped rubber strip to the front bar or both to get it fixed permanently.
hope this helps
