Nobody was nice enough to provide dimensions so I measured it myself. Here's the thread if anybody is interested:

fan diameter ~35mm
heatsink dimensions ~57mm x 70mm x 6mm
heatsink standoffs ~6mm

So , I have now got my board x570 taichi and one of the above coolers and there are two main problems 
 
I've fit the cooler , it fits on the chipset just fine .  However it then means that the 1st and  second pcie slots are unusable with a long gpu (gtx1080ti with water lock) .   The bottom slot is available , and may then be a option for some people . I however trying doing this in a inwin 303 and the bottom slot in that case is unavailable for any card as it's so close to the floor .   I have ordered a bracket to turn the card vertical.  This should allow for me to fit my card and  cool both .
 
The second problem is the metal cover that also acts as a nvme cooler .  This obviously does not fit any longer . There seams to be two options here . Either cut a section out of the metal cover which would work but destroy any resale value , so I will leave it off and use a aftermarket nvme passive cooler.   
 
 Iam still a fair ways off having it up and running but think I can see a way to the end , hopefully
