It is constant as the fan speeds up from zero. It becomes intermittent/rhythmic at a stable speed. I'm not making this up, I've got my face right in front of my card as it beeps at me.
This is also how I am experiencing it. I wish I could link video but my account is restricted.
As I posted above in a edit. As all three fans are identical as far as I know, the fact that everyone is reporting the same fan POSITION as being the problem would seem to rule out the FAN being the issue and it being either interference or issues with the PWM controller.
I think the fan position for most reports so far is a coincidence. For example, my problem fan is the middle fan. Our sample size right now is just super small.
"If I gently stop one of the fans, the beep is continuous while it ramps back up to speed and then intermittent once it stabilizes."
You're not reporting the same issue.
