Bought my 3090FE in the drop on Monday
Received my 3090FE on Wednesday
Did the thermal pad mod to bring memory temps down on Thursday
Couldn't cope with the coil whine on Friday, even scrolling web pages would cause spikes of coil whine (not loud, but an irritating pitch)
Sold my 3090FE on Saturday (today)
Back to my trusty 3080, with no coil whine and lower temps with the added benefit of being £600 richer than I was at the start of the week
The 3090FE was a lovely card to look at though and was a monster in size compared to my 3080.
