What Yard Operators Say
We had two ASIC models on our shortlist — both rated above 0.05 PH/s. Portalhemlockway's report showed that one drew 340 watts more than its spec sheet under sustained load, which would have pushed our breaker panel past safe capacity. We went with the other model and avoided a costly panel upgrade.— Tae-hoon R., procurement lead, Cheongju container yard
The noise readings at our fence line were exactly what we needed for the county review. Jae-won spent an extra hour repositioning sensors when the wind shifted — that attention to detail made the difference. Report delivery took six days instead of five, which was mildly frustrating during our permit window.— Eun-ji W., site owner, rural Gyeonggi
I appreciated that the cooling section didn't just say 'add more fans.' Hye-jin identified that our intake louvers were pulling exhaust back in because of prevailing wind direction. A simple baffle fix solved what we thought was a hardware problem.— Sang-ho M., yard supervisor, Sejong
Used the pre-purchase consultation before ordering twelve units. The fit-check caught that our container door height was 15 millimeters too low for the model we wanted. Saved us from a return shipment headache. The video call felt a bit rushed at 90 minutes for three models, but the written summary was thorough.— Young-sook L., independent operator, Daejeon outskirts
Extended Project Account: Sejong 40-Foot Conversion
From Empty Container to Running Fleet
A Sejong-based operator contacted us in March 2025 with a newly delivered 40-foot high-cube container and plans to install 24 miners rated at 0.08 PH/s each. The container had been fitted with intake louvers on one long side and a bank of exhaust fans on the opposite end.
Challenge: During the initial burn-in, rack temperatures in the rear third of the container exceeded 48°C after three hours, triggering automatic throttling on four units.
Our approach: We mapped airflow with temperature loggers at 12 points inside the container over a six-hour test period. Data showed hot air pooling above the rear rack row because the exhaust fan bank was mounted too low to capture the stratified hot layer.
Outcome: The operator raised the exhaust fan mounting by 40 centimeters and added a partial ceiling baffle. A follow-up cooling review two weeks later confirmed rack temperatures stayed below 42°C under full load. The operator proceeded with the full 24-unit installation.
Client note: “The annotated diagram in the report was clear enough that our local fabricator built the baffle without needing a second site visit.” — Min-jun H., yard supervisor
