Client Stories
Operator accounts from corridor surveys, placement reviews, and equipment shortlists across Jeolla and beyond.
Testimonials
Their placement sketch showed our exhaust fan was undersized by half — we were cooking hashboards at the back row while the front row looked fine on the pool dashboard. Retrofit cost money we hadn't planned, but the survey fee was trivial compared to replacing three boards.
Shortlist advisory kept us off a loud unit that would've violated our apartment complex rules. We went with their second pick — slightly lower hash but we sleep at night. Report was dense; took me two evenings to read properly.
Bench numbers matched what we saw after install within about four percent on draw. Corridor tracer video they sent helped our electrician understand why we couldn't stack racks against the south wall.
Case: Naju garage conversion
Situation: Two operators shared a 6 m × 4 m garage with one window intake and a passive roof vent. They planned four units above 90 TH/s combined.
Work: Corridor baseline survey followed by placement review. Tracer showed 18% recirculation at the rear rack position.
Outcome: Racks shifted 20 cm off the back wall, plywood baffle added below the window, and a 150 mm duct fan specified on the retrofit plan. Junction temps stabilized; one unit later sold because power contract capped lower than expected — unrelated to airflow but noted in their follow-up email.
Reservation they shared: “Wish the duct plan had included a parts list with local shop SKUs — we hunted fittings for a weekend.”
Case: Gwangju Seo-gu spare room
Situation: Single S19-class unit in a 3 m × 2.8 m spare room with shared wall to a child’s bedroom.
Work: Equipment shortlist plus half-day placement visit.
Outcome: Lower-fan-speed profile documented; operator runs night schedule at reduced clock. Noise at shared wall dropped to acceptable levels per their own meter. Hash sacrifice explicit in the report — no false promise of full-speed 24/7 operation.
Follow-up: Filter change interval set to 21 days after dust test; operator reports sticking to it for two seasons.
