Question Coil whine help ?

[ladislav12]

Hi, I recently bought PC. Components are:

• 7800X3D
• MSI MAG CoreLiquid A13 360
• 64GB DDR5 RAM
• MSI MAG B650 Tomahawk WIFI
• SAMSUNG 990 PRO 1TB
• MSI RTX 5070 Ti 16GB GAMING TRIO OC PLUS
• MSI MPG Velox 100P Airflow
• Corsair RM 1000x

It is running pretty quietly, FPS are great, productivity is great and temperatures are good. Even tried some benchmarks and lighter stress tests. However when playing games the PSU has really really annoying coil whine. If its really coming from PSU but It honestly sounds like it does. Not sure if there is some way how to test that to find out if its GPU or PSU, it just sounds like its PSU. I am really noise sensitive, I cant even hear my fans in new PC but coil whine is quite specific and annoying sound xd

Is there anything possibly I could do to maybe minimize that coil whine ? Thanks in advance.

You might want to take a sheet of A4 paper, roll it into a cylinder, then hold one end to your ear. The other end would be necessary to inspect for the source of the sound. Please take off the side panels when inspecting for the sound, we've seen people not bothered to take the panels off and then speculate.

Pass on a video with audio of what you uncover.

If it's any of your components, take a video with audio of the culprit and use that as info to pass onto your seller or the part's makers and see if you qualify for an RMA process.

What BIOS version are you on for your motherboard? Have you tried undervolting your GPU and processor?

Good idea, I could do that honestly, thanks. Some people already told me to try RMA process and I probably will anyway but at first I wanted to test some things to see if something helps or not. If not then RMA process. I will try to do that with paper but probably tomorrow.

Honestly dont even know what version of BIOS im running, should I check, like can it matter ?

Undervolting GPU all the way to 0.8V helped a bit but it was still quite annoying.

As far as i know, coil whine is not a sign that your PSU is going to stop working or something, so most people replace their whiny PSU's just because it's incredibly annoying, sometimes coil whine goes away after a couple months of use, some motherboards have "acoustic noise mitigation" that stops coil whine, but i think yours does not have it.

Yeah it is kinda annoying. Undervolting helps a bit, plugging PSU into another plug/outlet (sorry dont know the name of it, which one is right xd) helped a bit, never goes away. Right now I dont want to deal much with RMA, but I think I will be forced to do so anyway.

A new one of exactly the same model may be a little bit worse.
Or a little bit better.

Coil whine does not necessarily mean a 'fault'.

Yeah I know that. Thats true. If it would mean "fault" I would RMA it instantly. Thats kinda the thing, I wanted to try some possible solutions first till trying to RMA it, because that would be the last option. But honestly, seems like possible solutions are limited. Undervolting all the way to 0.8V helped the most - it still has coil whine but it is doing it like in intervals. 2seconds of very subtle coil whine and then like 2s of none, no coil whine at all. But just feels a bit weird to buy a PC for 2K€ and then undervolt it to get less performance xd Its either quieter PC or more performance I guess
