I am selling a lot of 4 Sapphire R9 280X 3GB GPU's w/ Arctic Cooler aftermarket coolers, which bring the heat and noise down considerably. The aftermarket coolers feature 3 fans instead of the stock two and as well as an aftermarket heat sink. Perfect for any mining rig setup. Here is the eBay page, will accept Bitcoin or Ultracoin as payment. http://www.ebay.com/itm/252137444221?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
