Nice comparsions, I like all those number,
but, let me ask you a question, I see your ambient is 36-40 degrees, I think it's in Celsius.
Where are you testing those cards, on the beach?
Something like that

. Open space without additional cooling, but also without a direct air flow. Static ambient airflows, so the Tamb, with power consumption of 3.6 KWh, reaches a limit.
When the private datacenter will be ready, the ambient temperature (Tamb) should be up to 23°C. I have the possibility to install these products in a Server farm with 22°C, but they are not yet ready to be sold, as they're instead working flawlessly.
The good thing is that these beauties don't require a low ambient temperature, due the low TDP, especially considering the massive airflow, in CFM, that the custom dissipation unit of the Venus1 is capable of delivering.
ps: I'll go to beaches soon, instead

not here, like I went couple of years ago (Isola della maddalena, Sardegna. Italy)

and unfortunately not here too (Punta prosciutto, Puglia. Italy)

but I could highly suggest you also this magnificient place, too (Campo Imperatore, l'Aquila. Italy)
