Soldato
My card also starts whining at 100fps which is too low IMO and the frame rate I like to play at. Have you tried loosening the block to see if that helps? I have read that it can sometimes make a difference. Also are both your gpus doing it or is it just one?
Both my cards unfortunately. Have fitted the backplates quite loose and also fitted new blocks as my original ones were quite warped which has made a difference.
But as stated with foam, cards sound fine. If you can't remedy the issue or get card back with the same issue then it's certainly worth a try.
