I got XFX 7900 GRE and I am looking for water cooling solution for this card.
From my search on internet I have foun out, that my card shares same board design (PCB number 109-D712A7-00_02.) as reference 7800XT for which Alphacools offer Eisblock Aurora.

From Image comparision it looks that only different thing is core and one DP replaced by USB. I dont know if there si die height difference between Navi 31 a nd 32 (i was not able to find this information) but GRE cards are using coolers designed for 7800XT and 7900XT. It seems that it should be direct fit with no interference as memory type is same, VRM are same and area contacting core is flat and large.
I tried to asked on FB group and I got pointed to email tech support where I got generic answer that 7900 GRE will not be supported.
I was hoping for more specific answer from somebody who got access to drawings and could compare die heights betwen 7900XT and 7800XT. If this height is same or difference is so smal that thermal pads will cover this difference.
It seems, that lot of 7900 GRE are based on this 7800XT PCB design. This knowledge could be usefull for booth sides. Card owners and Alphacool. With current overclocing options it seem that 7900 GRE will be popular card.
