Based upon my measurements I sent a message to Eddy for clarification. He said that the NF4 rev1.1 has a fitting range from 49,5 to 60,5mm so it will fit both the NB and SB chips.

Note, the NB/SB 1 will NOT fit b/c it only measures 53mm. A minimum of 55mm is needed to work.

So...all we need are ViperJohn's Heatsinks for the mosfets or EK mosfet waterblocks and it's a rap!
