Whirring like a horn when driving faster than 65 MPH?

Before 65 MPH everything is fine but anything above it there is a loud sound like a horn from the front end that doesn’t change pitch with RPM or speed changing until you go below 65 MPH, at which point it completely stops. I already checked everything I usually do when there’s an odd noise and because I was convinced it was the horn, I even hit the horn to see if it was stuck or there was a wiring issue, but it wasn’t the horn making the noise and it’s only a single tone horn. I looked on forums I belong to that I usually go to for Colorado/Canyon problems and can’t find a single comparable issue.
