Proof?

Because you said so I have to believe it?

More likely that the units got fried and these people are responsible and fixing the problem given the report from Toomin.

And you didn't answer the question why the 'retrofit'?

Obviously there were issues.

I'm not sure I can provide you with any proof that would suffice given I can't go back in time and take a picture posing in front of both machines with a time on a card. I never took any pictures while I was there out of respect. I can only show you a picture of the machines they hosted for me running at my 1MW facility still under construction. There are two electric services at my building so while the 1200A 480V service is being built and not currently energized, I have a wimpy 400A 240V service I'm tapping. The picture is a little old one rack has not been hooked up yet but it is now. The S1's in that picture were never hosted by ASICSPACE, that would have been a loss obviously. It's worth noting my most temperature intolerant miner would be the cointerra, overheating if the room just goes over 80F, and I have logs showing a stable hashrate on it for months while at ASICSPACE.

Re the retrofit it should go without saying; it is not a tier I datacenter and should not be expected to be built as such. I don't think there is a bitcoin mine on the planet over 1MW that doesn't need modifications to airflow after the heat is there. You can use smoke bombs all you want, use some formulas that make you look like math Jesus, and try to predict what will happen before the heat but you never really know until you put it into place. I would be more concerned if they were not constantly looking for ways to improve their airflow.

I don't need to do math to see that one fan in the air is not near enough. An asic data center getting exhust out is important.

Unless they changed their design and added a lot of extra gear that picture shows something not setup for a large quanity of gear. If they kept adding gear it's not surprising they would need a retrofit.

Unless there is a lot of gear behind where person is standing that we cannot see for ventilation.
