Heatkiller 3.0 - Bitspower 7/16ID, 5/8OD Matte Black Compression Fittings

Are these two compatible?
Would it work without the need of a rotary adapter?

If not, would it work with one compression and one of these + a compression?

I read somewhere that it didn't work with earlier heatkiller 3.0s but that watercool did a small modification and widened the spacing a tad earlier this year, can anyone confirm this?
