I was about to say I don't have it but now that you mention it sometimes I have had this odd buzz noise that goes up and down. But haven't heard it in a while.. maybe because my HVAC is always on now or got some windows down.
I've triggered the ECU fan with ISTA and heard it run and it sounds more to the right IMO than that buzz noise. I've searched before and it seemed to be the buzz was from waterpump but I'm not sure on that.
