"When play the game , fan start to spin with high RPM. The noise sounds like coil whine , so I thought it was coil whine and ignore the sounds. Last night the noise got worse so check the card , and the sounds came from the LED cover. When I press the LED cover noise disappear. So it seems the fan may contact the LED cover on high RPM. For me it happen when card is under load so fan start spin. Around 70% of fan speed is makes the noise. I found the left fan makes the sound for me(to find out I have stop the fan with my finger)."
"I noticed the same issue on my 3090 Strix OC last night too.
I can replicate it 100% of the time by just turning up the fan speed with the card at idle. It seems loudest for me at about 65% and the middle fan seems to cause it more.
Pushing on the lightbar doesn't make it go away completely but does decrease the sound significantly. Unlike in your video it decreases the vibration sound when I push on the lightbar on the right hand side (power plug end) of the lightbar about a third of the way along. Pushing where you did does nothing for me.
In all other respects the card works fine it's just a ****ty design/QC."
now Yeah I can confirm I have this vibration too with my shiny new Strix 3090 oc... Seems to happen at certain fan speeds....
My card also came with no plastic film over the lightbar so maybe that is normal. However, mine actually had some scuff marks on the lightbar straight out of the box! .
