1 Hz ticking noise coming from right vent of Yoga 710

I have a new Yoga 710. I have just noticed a faint ticking noise coming from the right-hand vent under the screen. When I say ticking, it is a softer sound than a click, a bit like a mellow kitchen clock. The tick sticks pretty close to 1 Hz (as far as I can measure it with my ear and a metronome). I looked for a software tool to monitor the fan speed but I couldn't find one that worked on this model of computer. I hear a fan starting up sometimes, but I have read (tell me if I'm wrong) that this model has two fans, so I'm not really sure how to measure the health of the other fan. My question is: Is this a hardware problem that will require me to mail the computer back to the retailer, or is it some other problem, such as the BIOS issue mentioned here in relation to an earlier Yoga model?

It seems like coil whine to me.

Thanks for replying! Does that mean that there's nothing to worry about beyond a very minor annoyance? I should add that I haven't heard the sound for the last couple of hours, so it's evidently an intermittent thing.

Yup, coil whine is normal.
