Here's an afterthought if you plan on using the D14 for a Haswell-E system.
  
 Two of us have been able to determine that a D14 will meet the cooling performance of a Corsair Hydro 110.  The two systems had load voltages of 1.35V.  I can't verify the room ambient for the H110 -- it wasn't reported.  Both systems were loaded with Prime95 sFFT for long enough to reach maximum temperatures.
  
 For me to do that with the D14, I had to lap the nickel off the processor IHS and cooler base, and use a thermal compound like either IC Diamond or (better) Coollaboratory Liquid Ultra or Indigo Xtreme.  @ 80F room ambient, the four-core-average temperature ranged between 65C and 68.5C.   I don't think it would have been that good if I hadn't made the refinements explained in this thread:

 With six cores and only so much overclocking potential, the D14 (or D15) will provide adequate cooling and maybe a small thermal margin for overclocking.  But you'll only get so far with the overclock no matter what, although I'd like to see more data, and Intel has many more of those same CPUs to produce -- who knows how the prospects may improve?
