I believe ID-cooling have other options, one that's essentially their take on the Zalman CNPS2x.
For anyone wondering (images are links to product page):
They are much taller than the CNPS2X is, though. The DK-01 is 52mm, the DK-01S is 43mm tall. There's also the DK-01T which seems to just be the DK-01 with a worse fan. Not sure if I'm a fan of those units.
