Windows 10: is this coil whine?

ive been having this for about a month now, performance and temps aren't affected at all by this, but the noise is a bit annoying, it only happens in-game https://www.reddit.com/r/laptops/comments/15i830n/is_this_coil_whine/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=1&utm_term=1

Thanks Sharvin.

Coil whine fix

The coil whine when idle makes the noise but when at 70 or 80 it stops but what i don't get is why is it when the backlight is on the coil whine stops

 

SLI can reduce/solve coil whine?

Good suggestions here. PSUs can mitigate coil whine if it's running on a good quality rail, but coil vibrations are normal if you're trying to push the card(s) power constantly, good example being unlimited rate of displayed frames. it's also not dangerous, and can even fix itself during heavy load. It's mostly just annoying to the ear. SLI won't do much if you already have issues with coil whine. You need to either replace the card under RMA (which few manufacturers do because inherently there's nothing wrong with the card), or you could try your luck with a new high tier PSU which may or may not alleviate it.
