Question Is this coil whine? Is it dangerous?

Could Potentially be coil whine, try folding a piece of paper into a cylinder and use it as a stethoscope to see if you can find the source. It can be GPU coil whine but is more likely to be PSU coil whine. Coil whine is more or less annoying than anything else, In extremely rare cases can it cause problems. If its either sources and you find it annoying try to RMA it if you still can, but shouldn't cause issues otherwise.

Sounds a lot more like a fan bearing.
if you change gpu fan speed does the noise change?
This noise happens normally when I'm playing a light game or when I stop playing a game. But it might be because I only notice the noise when I stop playing. Is it dangerous? I also turned on vsync and seems to be working, but I still hear it from time to time.

I've pin pointed it to the PSU. I just recently installed the PSU and my GPU and I haven't experienced any random shut downs or black screens so I don't think it is because of a failing component.

Alright since that's the case what you should know about coil whine is that it isn't harmful to your computer it's simply the vibrations from the coils as the electricity travels, this is usually more prevalent in cheaper PSU's being that this is a bronze, If you aren't bothered by the noise and don't feel the need to RMA it then just let me know one other thing, does your PSU fan run on idle?

Umm.. What?

It's not more prevelant in cheaper OR more expensive PSUs. If anything, it's LESS prevelant in cheaper PSUs because they use a high (out of audible range) frequency, which can lead to lower efficiency.

Higher frequencies can be good because smaller components can be used and ripple is reduced, but it's hard to find and MAINTAIN that balance and keep frequencies out of an audible range.

Hmm I see, not something I knew very much my knowledge lead me to believe more or less that cheaper Psu's had a higher chance of audible coil whine, glad i know that now at least, my last question was leading to possibly it being the PSU fan since that's where he had heard the sound coming from

Coil whine is always an indication of low quality cheap component.
Coils, transformers should be dipped in shellac for a specific time before they get used.

They are alwayss shellaced. But shellac alone does not prevent all audible noise.

So all of those power supplies I linked above use low quality, cheap components..... Fascinating. Yet you guys recommend them every day.

So which power supplies... or even graphics cards for that matter.... Do NOT use "cheap components" that are apparently "not shellacked" and therefore will never have coil whine, ever?

Either way though if it is indeed coil whine and you would want to potentially look for another one to reduce this, I'd say look online for multiple reputable "PSU Tier lists," and then compare the lists and find something suitable for your system, leaving a some headroom for your system as well always helps.
