Field-Replaceable Fan Module Swap
On-site cartridge replacement for intake and exhaust fans on miners rated 0.05 TH/s and above, without removing hash boards from the rack.
Rate basis: From ₩85,000 per fan module (parts + labour) · Typical duration: 20–45 minutes per unit · Location: On-site at your facility
Who this is for
Operators running Antminer, Whatsminer, or comparable ASIC units at 0.05 TH/s per device or higher who notice rising inlet temperatures, rattling bearings, or hash-rate throttling tied to thermal limits. This service suits both single-rack hobbyists and co-location tenants who cannot afford extended downtime.
What you receive
A technician arrives with matched fan cartridges for your specific shroud geometry. We power down the affected unit safely, release the cartridge latch, install the replacement module, verify spin-up and PWM response, and record inlet/outlet delta-T against your rack baseline.
Included:
- One or more field-replaceable fan modules (OEM-equivalent CFM rating)
- On-site installation and cable routing check
- Thermal reading sheet with before/after values
- Disposal of failed modules per local e-waste guidance
Excluded:
- Hash board repair or firmware reflashing
- Duct fabrication or facility HVAC modifications
- Units below 0.05 TH/s nominal rating
Process
- Intake call — You share model, fan count, and symptom timeline.
- Parts confirmation — We verify cartridge compatibility against our Busan stock or order overnight if needed.
- Site visit — Scheduled within 1–3 business days for standard requests; same-day when emergency slots open.
- Swap & test — Module replaced, unit powered, temperatures logged at steady state.
- Handoff — You receive a one-page thermal summary and recommendation for adjacent units if wear patterns match.
Preparation
Ensure rack access, clear workspace in front of the unit, and have your facility contact available for power-down authorization. Label any units already flagged by your monitoring stack so we prioritize correctly.
Pricing basis
From ₩85,000 per fan module including parts and labour for standard cartridge mounts. Multi-unit visits receive adjusted travel fees. Exact quote provided after model confirmation.
