Question about Noctua NH-D15 Chromax

The "normal" NH-D15 is the same size/height as the Chromax, so they are identical.
Height (with fan) 165 mm
Height (without fan) 160 mm
That's how it is with both.

It's nice that Noctua offers something other than the usual beige/brown with the Chromax series and this cooler. Because this colour mix does not meet my taste.
Of course, this cooler is, in my opinion, the result of many people buying another CPU cooler just because of the "Noctua colour".

The cooler looks very nice, almost as nice as the Dark Rock Pro 4 from be quiet! but only almost ;-)

I wondered about that too. According to the manufacturer's website, they are identical. I think the Digitec team made a small mistake here.
