Perfect for dual-lga1366 application.
I bought two of these for a dual-socket lga1366 build. I picked them because they are known to mount directly to the backplates that come pre-installed on many workstation and server boards (looking at you, supermicro). Mounting them was very simple. They have just enough height clearance to clear my ram, they're quiet, the sleeved fan cable looks great, and they keep my hexa-core xeon e5645s below 40 at idle. The fan bracket uses one clip per side to mount to the heatsink, and because of this it's much easier to remove the fan from the heatsink in tight confines than my 212 evo is with those four clips way down near the bottom of the heatsink. I purchased the pair of coolers with no expectations, but i am very happy with them, and i would buy them again if i ever build another system that required a cooler(s) smaller than a triple-140mm one the size of a question.
