Your wall fans aren't the only fans you pay for.
Basin reads the miners, power data, and fan drives already on site to find where facility fans and miner fans cost the least together — then keeps tracking that point as weather, load, and curtailment move it.
Live the same day it's installed. Reports use fixed reference rules, measured inputs, and exportable calculations you can audit.
Your wall fans and miner fans are fighting the same fight.
Slow the wall fans and miner fans take over. Speed the wall fans up and the miners relax — but now the facility fans may be doing work the miner fans could have done cheaper.
Somewhere between those two is the lowest-cost balance. It moves with weather, dust, curtailment, and fleet load.
A temperature controller cannot find that point. It stops when the air temperature looks right. Basin watches the full cooling tradeoff — wall-fan power, miner-fan behavior, temperatures, power, and hashrate — and keeps the site near the cheapest safe operating point.
Uses the gear your site already has.
Miner APIs are read-only
Chip temps, fan RPM, inlet temps. No firmware changes, no rack probes, no miner control.
Power comes from PDUs, meters, or calibration
Smart PDUs are best. If the site lacks them, Basin still works, but the first sweep calibrates the model.
VFDs are the only actuator
Basin writes fan speed only, through the drive or PLC, with bounds and fallback behavior.
One visit from connection to control.
Basin is installed, verified, and brought online in the same site visit. It connects to the telemetry and fan controls already in the building, confirms that each zone responds correctly, locks in safe operating bounds, and starts controlling airflow from the local PC. The control loop then keeps working against real miner and power data as heat, weather, and site load move.
Connect
One local PC connects to miner APIs, power data, and the VFDs or PLC. Basin reads the fleet continuously and only writes to the fan-control layer.
Verify
A short controlled test confirms that fan commands are followed, telemetry is clean, safety limits are respected, and each zone responds the way it should.
Control
Basin starts with bounded changes, holds thermal headroom, and adjusts airflow against real miner power, hashrate, RPM, and temperature data as conditions move.
Measured on your hardware. Reported against clear baselines.
Basin records power, hashrate, temperatures, fan behavior, and weather. Each report shows actual operation against an agreed baseline, plus three standard benchmarks.
Fans at max
Every facility fan at 100%.
Design-day setting
One fixed speed sized for the hottest conditions.
Monthly tuner
A simulated operator sets the VFDs once per month to the lowest fixed speed required for that month's conditions.
Every result identifies the reference used and whether it is measured or modeled.
How each hour is counted
Every hour, the claim is a subtraction: what the rule would have drawn, minus what Basin actually drew. Each piece is labeled by how we know it.
watts = k·RPM³, with k calibrated on your hardware at install.Where each claimed kWh comes from — typical first quarter
The estimated slice starts thin and gets measured away on its own. Watching it disappear from your own reports is the point.
| Saved vs. rule | kWh | @ $0.052/kWh |
|---|---|---|
| The monthly tuner — the diligent human | 168,600 | $8,766 |
| The hottest-day setting — the industry standard | 215,400 | $11,202 |
| Fans at max — the ceiling | 355,200 | $18,471 |
Pod A/B, where the site allows it
Start Basin on one pod or zone while a comparable pod stays on your existing controls. Same hours, same weather, same curtailment calls — with power and accepted hashrate normalized before comparison.
The trial is time-boxed up front. When it ends, reporting continues against the same fixed rules used from day one.
No forced before/after games
Basin does not schedule "off" periods, force reversion tests, or run your site worse to make a chart. And there is no savings-share billing: the report shows the value, but it does not set your bill.
If the math stops working, you see it first — and you can cancel.
The optimizer becomes your cooling command center.
Basin has to watch miners, drives, fans, power, and curtailment state to do its job. That same data gives operators a live view of the infrastructure around the miners — not just the miners themselves.
Basin does not replace Foreman or your miner management stack. It adds the cooling, fan, drive, and site-control layer those tools do not handle.
Catch what miner dashboards miss
Failed fans, VFD faults, stuck speeds, stale telemetry, rising miner-fan RPM, and cooling drift surface early — before they show up as lost hashrate.
One view across cooling and curtailment
See fan speed, site state, and real-time cooling behavior across every connected site.
Tune the optimizer to the site
Bias the control toward maximum savings, extra thermal margin, quieter operation, or reduced fan wear. Basin finds the best point inside the limits you choose.
Every failure moves toward safe airflow
Thermal events, missing telemetry, drive faults, and network loss pause optimization and trigger conservative airflow rules. Every control change and safety event is logged.
Built by an operator, not a dashboard vendor.
Basin grew out of years operating air-cooled mining sites — through curtailment events, comms drops, dust, failed fans, and sustained high-temperature runs where cooling performance directly impacted uptime.
It is new as a retrofit product. Installs are done directly, savings are verified against your own data, and early sites work closely with the founder.
Built from real site problems
Basin was built around the equipment miners already run: ASIC telemetry, PDUs, VFDs, curtailment, and the messy behavior between them.
The loop runs on site
The controller runs on a local PC, on your network. Remote access is outbound only, and the cloud is not required to keep the fans running.
Reverting is simple
As-found drive settings are recorded at install. Cancel anytime, switch back to local control, and the drives keep running inside their own limits.
Simple pricing.
Fifteen cents per miner per month, plus a fixed install. No savings share, no annual lock-in.

Book a site assessment because a fan setting that keeps miners safe can still waste power every hour.
We check VFD access, miner API access, PDU/meter availability, zone layout, and fallback behavior before install.
