Tried massing with the RPMs, tried messing withe the CPU voltage even... everything. everything is cool and perfect, but I try the most medium to the heaviest game... and it sounds like a taser in that spot... it's the most frustrating thing.

Didn't bother testing with Prime or IBT, but that's what I thought. makes sense. this whole thing is annoying... it's a new PC, and after the 2nd RMA. Edit: tried both... no buzz, still only 3Dmark.

Hello, I need your help. it started 3 or 4 months ago, after a year of usage my gigabyte z390 aorus pro started to buzz heavily from the VRM area on the IO side, but not idle, the idle sound is minimal and I'd have to nitpick and get real close to hear it. the electrical sound only ramps up in Game, a heavy game... like Division 2 or Destiny 2, anything heavier than Diablo 2 or Synthetik. I've tried everything, disabled CPU boost, checked the PSU cables, sent the GPU, CPU, PSU and MOBO to RMA... got a new MOBO the 1st time I RMA'd (same model), still buzzing sound in games. sent it to RMA again, got a new MOBO and MSI this time, still buzzes. changed RAM to 2400 instead of 3200, disconnected the Corsair AIO RGB usb cable, changed PSU CPU power cable, even after RMA-ing everything. twice they said everything was ok, and they can't hear buzzing while testing it all. I don't know what to do. updates BIOS, downgraded BIOS... changed wall sockets, changed monitors, changed PC power cabels, changed DP screen cables. (all this after RMA, I still have warranty). reinstalled windows... disabled XMP... everything, tried everything I could. changed extension cords... everything. next thing I'm trying is changing the cooler, disabling all the RGB and RGB hub. Funny thing, IDK if it's a problem, but the CPU is base 3.6k and boost 4.7k Ghz, but it boosts on its own to 4840Ghz and a little beyond, I'm confused. Spec: MOBO - MSI z370 gaming pro carbon CPU - 9900k RAM - G.skill tridentZ 3200Mhz GPU - Asus Strix 2080ti SSD - Samsung 850 EVO 250Gb M.2 - Samsung 970 EVO plus NVMe 500Gb PSU - seasonic focus plus platinum 850W CPU cooler - Corsair H115i RGB PLATINUM 280mm AIO Got 3 Corsair ML RGB fans connected too, and a fan hub and the RGB controller that comes with the Corsair stuff and it's in a corsair case... not that it matters, it's a 500D. and the Screen is an Asus with G-syinc... I'm adding all this because I'm very desperate. Last note... it does not buzz (the VRM area near IO) when I bench in Cinebench or FurMark, but it does in 3Dmark. Again, the PSU, GPU, CPU, and MOBO got RMA'd, everything came back working and no noise was reported.RAM got changed, cables got changed. I would be very thankful for any help, I don't know what to do and I have a $3000 netflix watching brick on my desk. Listen in a higher volume, I recorded it not so great... but trust me, it sounds like a taser. opened and closed case.
