It's a modular 850w corsair and I tried powering the cards using different cables/adapters from different "ports" on the psu but the whine remained. My worry is that the psu could be slowly killing the card but I really have no way of knowing.

When I had coil whine on my quads, the noise fooled me. I thought it was one of my cards. Almost yanked the loop apart till I by chance had my ear next to the psu. It had a definite whine, but much lower frequency. I rma'd the psu. After swapping in the replacement, all coil whine was gone, from the cards too obviously. Bad power can do strange things to these cards.

Hmmm. I do have my old ocz psu in my closet so I'll swap it in and see if the whine is still there.

There is nothing wrong with returning and getting your money back between the 30 days or if you are not satisfied with said product. I am not happy when nearly every other card can reach certain clocks and very few cannot. I will return it as a last resort only

And don't hate the player because they offer 30 day returns if aren't happy or have an issue. Besides it will be listed as an open box item making the buyer happy with a discounted card that I have to pay shipping and restocking on a percentage of the card.

"that's why you will never have nice things with that logic"

Wow some crazy clocks in here on water. I plan to go with either the Asus DC2 or Msi TwinFrzr and set both cards to 1200/1600mem and be done with it. Will I need any voltage increase to attain this?
