Accounts from operators who needed shelf-level clarity.

Operator Testimonials

We had four units crammed into a 6U half-shelf and could not figure out why the top two kept throttling. Jae-ho measured intake temps and found our blanking panels were missing on the shelf below. Simple fix, but we would never have spotted it without the thermal photos in the report.
— Hyeon-woo R., home operator, Cheongju
The bench test saved us from buying six used miners that were already below the 0.05 TH/s floor. Honest numbers, no pressure to buy through them — because they do not sell anything. The only downside was waiting ten days for a slot during a busy month.
— Eun-ji M., small farm operator, Daejeon
So-yeon walked our electrician through the PDU load spreadsheet on site. He understood immediately which circuit was overloaded. Report was thorough, though I would have liked a Korean-language summary alongside the English version.
— Tae-sung L., facility owner, Sejong
We commissioned a full-rack assessment before expanding from eight to sixteen units. Dong-wook's report flagged that our ceiling clearance was insufficient for the exhaust path of the larger ASICs we were considering. We changed models before spending the money.
— Ji-woo K., operations lead, Gongju

Sejong Half-Rack Reconfiguration — March 2025

A client running eight units across two half-rack shelves in a converted storage room contacted us after hash-rate dropped 12% over two months. They suspected failing units but could not isolate which shelf was affected.

Our visit: We logged hash-rate per U-position over four hours, mapped exhaust temperatures, and found that a relocated network switch was blocking 40% of the rear grille on Shelf B. Units on Shelf A performed within 2% of manufacturer claims; Shelf B units averaged 9% below.

Outcome: The client repositioned the switch and added a 40mm rear spacer bracket. A follow-up log two weeks later showed Shelf B units recovering to within 3% of rated output. Total engagement cost: ₩720,000 including the return verification visit.
