Noctua NH-U12s Compatibility

I have the gigabyte 970A-DS3 which has a 1x slot at the top and followed by a 16x slot and Im am afraid that if I by the noctua NH-U12s that the fan will overlap that 1x slot which I need to use for a wireless network card, and the 1x slot at the bottom is overlapped with my GPU. Anyone had any personal experience or know if I will run into any clearance issues with this CPU cooler?
