My iMac has an intermittent wobbly fan and I really need to get it booked in while it's still covered by AppleCare. It's not the noise that the fans make when they're ramped right up but can happen at any time and a bit annoying. It sounds as though one of the fans is wobbling (I've recorded it on my iPhone, zipped it and it's attached to this post). It is intermittent though, I can go for days without it happening. With all the stores closed, does anyone have any experience of the current repair service? Are they doing collections? I know I could ask Apple but I'm sure we have some Apple employees here who might know the answer. Thanks.
