Workshop Feedback & Case Studies
Authentic reviews and technical outcomes from independent operators and electricians who attended our Dawson lab intensives and on-site advisory audits.
Michael visited our farm shed to audit our 3-phase switchboard setup. He immediately identified that our neutral line on the sub-board was under-sized for non-linear continuous loads and caught a breaker terminal that was running at 68°C under thermal scan. His report gave our local sparky exact specifications to rectify the wiring before we added our second compute rack.
The two-day hardware masterclass in Dawson was very thorough on physical board repairs and voltage step-downs. The hands-on time repasting hash boards with phase-change material directly solved my overheating hash board #2. My only minor critique is that day one is extremely fast-paced if you haven't held a multimeter in a few years, but the small group of six meant Michael spent extra time walking me through low-dropout rail diagnostics.
Marcus walked us through real-world dynamic throttling scripts interfacing directly with our Fronius solar inverter API. We can now safely ramp hash board draw from 800W up to 3.4kW without inducing sudden thermal shocks or tripping inverter safety cutoffs during intermittent cloud cover.
Elena helped us design an isolated hot-air plenum with acoustic baffles for our garage workshop. The high-pitched fan whine dropped from 79 decibels down to 44 decibels measured at the boundary fence, which completely solved our neighborhood noise concerns while keeping intake temperatures below 24°C.

Resolving 42°C Summer Thermal Shutdowns on an Orchard Facility
Background: An orchard operator in regional Victoria with a 45kW rooftop solar array was experiencing recurring emergency shutdowns on six ASIC compute units whenever ambient outdoor temperatures reached 36°C in January.
The Intervention: After attending the Thermal Engineering & Airflow Optimization Workshop in Dawson, the operator collaborated with our team to construct a custom negative-pressure exhaust wall plenum and replace the stock factory thermal compound with Honeywell PTM7950 phase-change pads across all eighteen hash boards.
The Result: Average chip operating temperatures dropped from 84°C down to 69°C during peak 41°C ambient afternoons, eliminating high-temp alarm shutdowns entirely without reducing hash board clock frequencies.
Project Metrics & Verification
- Intake Temp Delta: Maintained under 28°C inside plenum
- Thermal Compound: PTM7950 Phase-Change Material
- Acoustic Attenuation: 22 dB reduction with rockwool baffle intake
- Electrical Protection: Upgraded to Type-B 30mA RCBO breakers
- Uptime Achievement: Zero thermal shutdowns throughout February heatwaves
