There are two different types of ILM (Independent Loading Mechanism) for Intel’s LGA2011 based Xeon CPUs: Square ILM with 80x80mm hole spacing and Narrow ILM with 56x94mm hole spacing.



 The mounting system of the NH-U12DX i4/NH-D9DX i4 3U/NH-U9DX i4 is fully compatible with both types.


These coolers can be made compatible with LGA2011 Narrow ILM with additional mounting parts:

  • NH-C14
  • NH-C14S 
  • NH-D9DX i4 3U
  • NH-D9L (chromax.black)
  • NH-U12DX i4
  • NH-U12S (chromax.black/ SE-AM4)
  • NH-U9DX i4


The additional mounting parts needed can be requested free-of-charge via this order form on our website.
