thanks again for your reply Colif. i really don't know if it's really fan bearing making the noise or coil whine? did it even possible for GPU to get coil whine without load and only fan spinning using Afterburner? i just do the test again and record it. i'm upload the video here: https://drive.google.com/file/d/1joLQP4NKGhGAtfGe6iT60CRTV_oMXcuV/viewI doubt the person who made this thread will ever see your answer as it seems they deleted their user at some stage.
i don't think I get coil whine on my Red Devil. I know I can hear the fans if they are on, but I wouldn't call it a buzzing noise. my case fans are noctuas so I don't hear those unless I let them all run at same speed. Intakes are 2 Corsair ML120 which are fairly quiet as well . PSU also has a ML fan... Some days the loudest part of PC is the GPU fans.
Think I disable my MSI fan curve, as its not really necessary to have GPU at 25c all the time. Afterburner overrides the radeon settings so even though it thinks its running at defaults, I have to choose quiet and then default again to get fans to stop if Afterburner before.
I had a 2070 Super before this which didn't run its fans unless card was over 60c, it was only in the weeks preceding replacing it that I used https://github.com/Rem0o/FanControl.Releases to control its fan - it doesn't work with AMD cards.
Seems the fans are meant to be quiet
i can find results for coil whine on the card, but not noisy fans
coil whine can be reduced by controlling frame rate. Its only high frame rates that normally cause it
I have set radeon chill up so my max frame rate is 143 and my minimum is 141. My screen max is 144 but I have seen it mentioned that running 1 less just makes it less likely to cause tearing, Setting a max might also reduce coil whine and could explain why I haven't heard it.
can you help me hear it too? thank you.
when i try to stop the fan using my finger before they spin (before i turn on the fan with Afterburner), i hear small buzzing in the fan cable area (fan cable that connect with PCB), but it so small.
