So my GPU (only 3 months old and doesn't really work hard) has began making this strange noise. I thought at first it might be coil whine how ever it's not high pitch and every coil whine video I've compared it to doesn't match. The noise happens when I first boot my PC then will cut out until I put load on it. Fan speed how ever doesn't make the noise appear, I can run my fans at 100% and no noise, but if I start putting load then this noise happens.

Here is a recording taken using my iPhone 5s (Please ignore the static, I couldn't stop it weirdly, you can hear it at the start, then it stops then comes back around 9 seconds in, it is louder at times best use headphones to hear it sorry) - https://youtu.be/slE8msqdS6A

What do you's think? Will Warranty resolve this? it irritates my ears and can get a little loud.

Thanks all.
