Air-Cooled Miners That Actually Run Where You Put Them

We review, bench-test, and commission hashing hardware at 0.05 TH/s and above — focusing on units that vent heat without plumbing, chillers, or reworked electrical rooms.

Why Operators Call Us

Bench Reports You Can File

Every reviewed unit gets documented hash rate at wall draw, intake temperature, and fan curve notes — written for your electrician and your accountant, not a forum thread.

Straightforward Air Paths

We specify ducting, clearance, and filter schedules for machines that reject heat into the room. No immersion tanks, no custom coolant loops unless you already have them.

Local Commissioning

Technicians based in Cheongju travel across Chungcheong for on-site wiring checks, firmware baselines, and first-48-hour stability watches.

From the Field

Recent notes on ventilation, power budgeting, and hardware that held spec past the first week.

Operator Voices

They flagged that our 0.08 TH/s units were choking on a shared 20A line before we burned a breaker. Install took a day; hash held within two percent of the bench sheet.
— Min-jun H., small warehouse, Daejeon
Honest about what our garage could support. We ended up with fewer machines than planned, which was the right call — though I wish the report had arrived one day sooner.
— Soo-yeon K., home operator, Cheongju
