Setpoint
Cooling control for air-cooled Bitcoin sites
Local VFD control for mining sites

Stop wasting power on cooling.

Setpoint controls exhaust VFDs from a local site computer, watches miner behavior, and keeps the site near the lowest-cost cooling point. Less fan waste. Less noise. Better visibility. Safer remote curtailment.

Built for air-cooled ASIC sites with VFD exhaust fans. If you do not have VFDs yet, we can help you choose a retrofit path that fits the site.

Find the lowest total cooling power.

Lowering exhaust speed is not the goal. The goal is the best split between exhaust fan power and miner fan power as ambient conditions change through the day.

How the balance moves through the day

Cooling has a moving sweet spot
Too little exhaust makes miner fans work harder. Too much exhaust wastes facility fan power. As weather changes, the best point moves.

Setpoint follows the moving sweet spot to reduce total cooling power, not just exhaust fan speed.
Minerguard: When miners need protection, Setpoint can move above the lowest-power point. Safety comes before savings.

Why balancing miner and exhaust fan speeds matters

Power ≈ Speed³
Fans follow cube law.The power a fan uses grows with the cube of fan speed, so small speed changes can create large power changes.
Miner fans react automatically.They spin as needed to cool themselves at the current air temperature and pressure.
Exhaust fans control pressure.Setpoint adjusts facility exhaust fan speeds to take work off miner fans before exhaust power gets too steep.
The bottom of the U moves.The balance creates a U-shaped total-power curve, and changing air temperature moves the lowest-power point through the day.

More than a fan schedule.

01

Remote site control

Control fan groups, miners, and recovery from one workflow so curtailments do not depend on manual site-by-site steps.

02

Tune to your priorities

Run the system for maximum savings, quieter operation, or longer equipment life as site needs change.

03

Follow the weather

Handle winter temperature swings automatically and capture cooling savings on mild days, even during summer.

04

See site efficiency

Get visibility into site performance, filter issues, hot machines, VFD faults, and hardware failures before they become expensive surprises.

Practical at the site level.

Setpoint runs on site, controls grouped exhaust fans through VFDs, and stays simple for operators. During setup we also catch the normal field issues that often hide cooling savings.

What we pay attention to

  • VFD setup, wiring, faults, and control mode problems
  • Containment gaps, recirculation, leakage, filters, and louvers
  • Fan noise, vibration, bad bearings, and unstable ramps
  • Switching, network access, device naming, and telemetry gaps
  • Remote alerts, visibility, and curtailment workflows that operators will actually use

These checks are part of a clean deployment: better inputs, steadier control, and results operators can trust.

Works at any air-cooled site with VFDs.

The best sites already have VFD exhaust groups, power data, and miner access. Sites without VFDs can still be strong candidates if a retrofit makes sense.

Best fit

Air-cooled ASIC sites with grouped exhaust fans, measurable power, network access, and operators who want fewer manual cooling problems.

If you need VFDs

We can help think through fan groups, drive sizing, control approach, and common installation issues before you buy hardware.

What the call covers

Fan layout, miner groups, PDUs, PLCs, switches, connectivity, airflow pattern, install timing, and what a useful first deployment should prove.

Cooling control should pay for itself.

Setpoint is built to cut cooling waste, quiet the site, support remote operations, and make hardware problems visible without depending on the cloud to keep fans safe.
