Buzzing noise when any activity (idle)

[u/amzkeh]

So I recently built my new pc, performance, temps etc are fine. PBO +200, CO -20, slight GPU OC, all stable, tested with cine, OCCT and dozens of hours of gaming.

Specs:

X870e tomohawk mono

9850x3d

MSI 5080 trio x

32gb DDR5 CL36

2tb 990 M2 drive

Corsair 1000w Gold PSU .

However I noticed that there is some kind of buzzing/static/surge kinda noise. Not sure if it's happening under load as headphones are on and I'm into the game, with fans also little higher potentially drowning it out, however when I'm desktop, I've noticed when any activity occurs , i.e. whenever I scroll the mouse or browse windows folders etc the noise occurs for that exact moment I'm scrolling or clicking etc, it doesn't persist before or after. This leads me to believe it's potentially CPU quickly spiking in power when activity occurs? Is this normal? Just something annoying I have to deal with? Is this what they refer to as coilwhine?

In the video i have shown that the noise occurs whenever i scroll in this example.

Coilwhine GPU

Oh really? Even with the GPU fans not spinning/inactive?

Maybe PSU mine came from PSU and GPU even scrolling on amazon.

At its core, coil whine is an electrical noise. It occurs when electrical current passes through components that contain coils or inductors, causing them to vibrate. These vibrations can produce an audible sound, typically a high-frequency squeal, buzz, or whistling noise

What confuses me though is how the same noise doesnt occur under load where surely electrical noise would be higher? But it does occur when just browing chrome?

turn off google chrome hardware acceleration and try it again. if nothing changes try to change the windows monitor refresh rate between 60-120-180hz

if it goes away then its 100% gpu coil whine.

the frequency changes depending on the gpu load. coil whine can occur at around 15% gpu load but not at 100%. it can also happen during the jump from 0% to 15% load, but not necessarily when going from 15% to 100%.

People automatic say gpu coil wine but i bet psu is the issue if such coil wine appear under no or low load.

Fucking mine can coil wine almost all the time at some point under 20%gpu load but no wine at high fps 100+ or full load.

Got +- the same noises with MSI 5070 Ti and it was one of the GPU fan, so I just limit RPM via MSI Afterburner and that it.

Just try different RPM via Fan Control or analog and check the noise.

the gpu fans are not active in this video

Minha GPU eu desconfio do mesmo barulho, porém só acontece com algumas texturas e cargas

Probably PSU coilwhine. I had this issue and I changed mine to a newer one and it went away.

At least its not the old BEEEEEEP of the flooded input buffer
