HIS has announced the RX 460 Slim-iCooler OC, which is a single slot, pci-powered radeon rx 460. I haven't found an official product page yet, but the news is being posted on some tech sites. The fan is said to be idle under 60 degrees celsius.
EDIT: the product page doesn't seem accessible atm, but there's a copy in google's cache: http://webcache.googleusercontent.c.../product2-940.shtml+&cd=2&hl=nl&ct=clnk&gl=be
