In other news, ASICSPACE fired their CEO, Damir Kalinkin, last week. I believe the exact process was that the shareholders held a vote of no confidence, then cleared out the Board of Directors (of which Damir was a member), and then the new Board fired Damir. In my (biased?) opinion, Damir was the worst part of ASICSPACE, and responsible for the most egregious misdeeds I have heard attributed to them. With Damir gone, I expect ASICSPACE to improve considerably. Robert is a nice guy, and I like him. From what I have seen, Robert wants to treat his customers properly, unlike Damir, who treats customers as a resource to be exploited.

However, I do not see how Damir can be responsible for the heat, airflow, and networking problems that ASICSPACE has had. He is not a technical person at all. Those issues were due to the decisions made by the engineer and contractors who built the facility and the person who oversaw them, Robert.

When I was at ASICSPACE earlier today, the conditions were considerably improved. The nine flexible ducts that were previously just neutral pressure outside-air intakes have now been connected to a 125 ton portable AC unit on a trailer, powered by what appeared to be a 400 amp 480V 3-phase connection. I didn't go into the cold aisles, but they appeared to be only slightly negatively pressurized relative to the hot aisles, maybe around 10 or 20% of what they had been at before. The general building interior (contiguous with the hot aisles) was strongly positively pressurized relative to the outside air, and the airflow out the open front door was very strong, maybe 50,000 to 100,000 CFM. The exhaust air from S4s felt like about 40 to 45°C, suggesting cold aisle temps around 30 to 35°C. Still high, but no longer unsafe. Most of the miners in their facility appeared to be on and hashing, although I did hear S4 beeps coming from somewhere.

ASICSPACE appears to be making a good faith effort to maintain proper operating conditions in their facility. They are putting a lot of money behind that effort. Unfortunately, they are spending it on the wrong things, like the air conditioning unit instead of a bunch of high-throughput fans. They don't need colder air, they just need more fresh air. However, the AC unit they are renting did come with a large fan inside, so there's that.
