Our System: Precision Noise & Airflow Engineering
Hodlhash uses a multi-layered solution that goes far beyond stock mining setups:
- Aftermarket Control Chips
These custom chips allow us to remove the noisy stock fans from miners and replace them with a single 8-inch high-efficiency fan — fully controlled by the miner based on real-time temperature data.
- Custom Shrouds for Air Redirection
Our custom shroud designs eliminate the high-pitched “whine” of small fans by channeling air smoothly through an 8-inch duct. This duct can be routed into another room or connected to a ventilation system — keeping miners out of their own hot exhaust air.
- Intelligent Airflow Management
Hot air is exhausted efficiently, while fresh, filtered air is pumped into the miner zone. This reduces recirculation of heat, extending the lifespan of hardware and improving performance.
Results: Real-World Benefits
- Drastically Reduced Noise
Mining systems become acceptable in residential, suburban, or community adjacent areas
- Improved Cooling & Longevity
Redirecting heat ensures miners don’t choke on their own exhaust, reducing thermal strain.
- Higher Efficiency
Smart fan control and cooler air intake reduce energy costs and component wear.
Modular & Scalable
Our Designs can be applied to:
- Single-unit residential setups
- Garage and basement builds
- Mobile flare mining units
- Large-scale warehouse racks
Modular & Scalable
At Hodlhash, flexibility is built into everything we do. Our mining systems are engineered to be completely modular, meaning they can be scaled up or down to meet your specific needs — whether you're running a single unit at home, outfitting a garage or warehouse, or deploying a mobile flare gas container in the field. Every component — from our custom shrouds and ducting to our integrated smart fan systems — is designed for easy configuration and expansion. This makes it simple to add more miners, redirect airflow, or adapt to new environments without tearing down your existing setup. Whether you're just getting started or looking to grow your operation responsibly, our infrastructure is built to evolve with you.

The Alternative: Risk of Shutdown
Recent shutdowns in Texas, Pennsylvania, and Norway show that crypto mining operations that fail to manage sound and airflow properly are now a regulatory liability.
With Hodlhash systems, you build for the long term — not the next complaint.
