Item is brand new, factory sealed. This is a version 2 model (see S/N in image 3), part number FD-W-L1-S2811. This model is a 280mm radiator with 2x black 140mm fans. To view full features & measurements, see Fractal Design's specifications page (unfortunately ebay removes links).
See 'Socket Compatibility' for supported motherboard/CPU sockets. LGA 1700 compatibility is mentioned on the box (see image 2), but according to Fractal Design's specifications, may not include mounting hardware for it depending on the manufacture date. This is fair warning that you may need to contact Fractal Design for a bracket or purchase it separately.
