I have a Diamond R9 280x OC edition, and it's been getting hot so I purchased http://www.newegg.com/Product/Product.aspx?Item=N82E16835186064 to try to get the temps down. I then realized I was an idiot and didn't FULLY check if it was compatible to put on my card... would this work, or should I cancel the order?
Hard to say since R9 280Xs are all non references. They do have an Accelero for R9 280x specifically.
