As your attorney, if these n@b hawks had told you at the outset that the gfx card had coil whine you wouldn't have bought it from them in the first place.
Most gamers need a gfx card that sits in their rig by your desk (like your set up) and we accept it has a level of fan noises levels and little else.
The item they sold you is not fit for purpose, it is defective and not adequate quality insist on a full refund. Be business like and polite. Give them 2 weeks to refund. Don't accept the card return. If they do not respond write a formal letter of complaint and 2 more weeks. If no joy pass it to a solicitor. I would not get into a prolonged email battle with the company testing the card - you tried it - you returned it - you want a refund.
