Short notes
They found dust packed behind a factory foam pad I did not know existed on my 0.12 TH/s unit. Fan noise dropped six decibels after I followed their mesh swap guide.
— Yong-su H., apartment mining closet, Incheon
Bench review confirmed my used unit was 4% below advertised hash. That honesty saved me from buying two more of the same model.
— Erin M., expat miner in Songdo
The laminated card on my rack is worth the visit alone. My teenager now does the weekly brush-down without me nagging.
— Ji-hye R., converted parking-space setup
Report was detailed but dense. I needed a phone call to understand the thermal images—glad they offered that at no extra charge.
— Tae-woo S., six-rig garage farm
Extended story: Bupyeong garage retrofit
Min-jun K. ran three units between 0.06 and 0.11 TH/s in a shared garage near Bupyeong station. Yellow-dust season brought visible grey film every ten days. He booked an on-site assessment in March 2025.
We mapped a negative pressure leak through an ill-fitting garage door seal and found that his cheapest pre-filter was collapsing into the fan housing. We specified a rigid mesh frame he could build from local hardware store stock and shifted his deep-clean interval from weekly to every eighteen days.
Six months later he reports no thermal throttling events and has booked a filter schedule update before the next heating season.
Extended story: Songdo bench verification
Erin M. purchased a second-hand unit advertised at 0.09 TH/s. Before installing it in a bedroom closet she sent it for bench review. Our log showed 0.086 TH/s at measured power—within tolerance but below her seller’s claim.
The report gave her documentation to negotiate a partial refund and included intake photos showing dust in the PSU shroud she would have missed. She kept the unit, added an external pre-filter box we sketched, and later booked an on-site assessment for a second machine.
