Question XFX 7800 XT MERC - Coil Whine but only in FN

[rism]

Hi guys,
I recently build a new gaming pc with a XFX 7800 XT MERC (Brand new). I noticed it has coil whine but so far I noticed only in FN, in other games such as CS2/OW2.
Also I hear the static noise via my wired headphones, will it be gone with wireless headphones?
Should I undervolt? Did anyone have this problem with this card?

Coil whine is generally directly proportional to output frame rate. You can try turning on V-Sync or VRR to limit it. But if you want those 200+ FPS you are kind of stuck with it.

Best bet to get rid of noise in your headphones is a discrete sound card or a USB DAC. USB DAC are the standard for audiophiles.

Your onboard sound may not be shielded well enough to handle the noise your GPU or PSU is generating. (I had this problem once long ago, and ended up using a sound card for a while, people could hear my GPUs on my Mic input.)

Indeed I just tried recording to check if the noise was getting on the mic and it did. My question is if I get for example Razor Blackshark v2 which are connected via a bluetooth USB this issue should go away right?
