Testimonials
We were about to order six ASIC units at 0.15 computing power for our converted office storage room. The assessment showed our HVAC could only handle four at sustained load. Repositioning saved us from tripping breakers every afternoon — though I wish the acoustic section had included weekend noise comparisons since our building is quieter then.
The hashrate benchmark on our GPU array showed 7% below manufacturer claims at our actual room temperature of 28°C. We used that data to negotiate a partial credit from the supplier.
Procurement consultation helped us compare lease terms across three vendors. The spreadsheet alone justified the session cost. Dae-sung was direct about which lease structures had hidden maintenance clauses.
Installation supervision caught a PDU placement error our contractor would have made — mounting it directly behind the exhaust path of two ASIC units. Minor detail, but it would have shortened fan lifespan noticeably.
Project Account: Incheon Logistics Hub Pilot Room
Client: Regional logistics cooperative testing mining as supplementary revenue Room: 65 sqm converted storage area, single 100A circuit Challenge: Needed rigs above 0.05 computing power but constrained by lease agreement prohibiting structural modifications
Appsycamorefield assessed the space over two days in March 2024. Thermal mapping revealed a persistent hot zone near the west wall where summer sun raised ambient temperature by 4°C compared to the interior. We recommended positioning racks along the north wall and adding two portable exhaust fans rather than permanent HVAC installation — keeping the lease compliant.
The shortlist narrowed fourteen candidate models to three ASIC units at 0.08 and 0.12 computing power. The client purchased four units at 0.08, ran a 30-day pilot, and reported stable hashrate within 2% of benchmark predictions.
Outcome: Cooperative approved expansion to eight units. Follow-up maintenance planning scheduled for Q3 2025.
Project Account: Suwon Tech Park Mixed Hardware Room
Client: Small operations team running both ASIC and GPU equipment Room: 40 sqm, dual-circuit electrical, existing server rack infrastructure Challenge: Mixed hardware created uneven heat distribution and unpredictable power draw spikes
Our benchmark team tested five ASIC units and one eight-card GPU array over 72 hours. Data showed the GPU array caused 15-minute power draw spikes that the ASIC-only power model had not accounted for. We restructured the PDU layout to isolate GPU power from ASIC circuits and produced a maintenance calendar with staggered fan cleaning intervals.
The client noted that report delivery took six days instead of the quoted five, but the thermal recommendations were immediately actionable.
