When the GPU is under heavy load the fans are also at higher speeds, when the card is almost at idle the fans are very slow or even at idle, this logic that it can't be the vram because it doesn't happen at full load doesn't make sense to me.
With the card at idle the vram is getting little to no fresh air.
This is most likely a vram issue specific to whatever is happening to those cards. What is the vram clock speed when this happens, when the machine is idle? There is issues with vram clock speeds at 100% even at idle in certain situations with amd, nvidia and even intel cards. Has anyone opened these cards to see the thermal pads? etc...
This has nothing to do with drivers.
VRAM chips, especially GDDR6, are designed to run up to 105C no problem, they also don't dissipate that much heat at idle, <20W, this can't be a temperature related issue.
