As per title:
Enerdyne Solutions and EK Water Blocks have an announcement to make: EK-Supremacy EVO Elite - Intel 2011 and it's Indigo Xtreme applicator are incompatible with LGA-2011-3 CPUs (X99).
The cause of this incompatibility is the IHS used on Intel Core i7 5800/5900 series CPUs is larger than the lid used on 2011-0 generation CPUs. If installed using the same orientation as the 2011-0 CPUs, the thick, blue stiffening member on the current EK-TIM Indigo Xtreme for socket 2011 will be caught between the waterblock and 2011-3 lid, causing a total reflow failure. If rotated 90° from the current orientation, the vent hole will be exposed and fill with molten alloy. In addition, the blue alignment ring doesn’t match the larger lid and will facilitate misalignments. In short, we don’t see a straight-forward work-around to adapting the current 2011 IX model.
However, new EVO Elite - Intel 2011-3 as well as new IX applicator are in the works and will be available for purchase by early Q4 2014.
