i just changed the cables but with no luck ;(
but after trying to pinpoint the noise im actually not sure it is from the graphics card, since the noise also is verry loud on the back of the PSU where the air flows through.
so unless someone post anything i can try to fix it ill most likely be disconnecting everything and sending in the PSU for a repair.
thankyou for the advice this far.
Have a look and see if the cable that provides power to the fans in the graphic card is touching a fan blade. I had that once. Screeched like a wild beast.
What board is your card in?
