Avalon Miner A1566-185T Noise Levels and Acoustic Performance: A Practical Guide for Mining Operators
Introduction
The Avalon Miner A1566-185T is a high-performance Bitcoin mining rig designed for efficiency, durability, and profitability. While much attention is given to its impressive 185 TH/s hash rate and 18.5 J/TH power efficiency, one critical factor often overlooked is its noise levels and acoustic performance.
For mining operators—whether running home setups or large-scale farms—noise can significantly impact operational feasibility. Excessive sound levels may lead to regulatory restrictions, worker discomfort, or even residential complaints. Understanding the A1566-185T’s noise output helps miners optimize placement, cooling, and soundproofing strategies.
In this article, we’ll break down:
- How loud is the Avalon A1566-185T?
- What factors influence its noise levels?
- How does it compare to other miners?
- Practical solutions to reduce noise without sacrificing performance.
Understanding Noise Levels in ASIC Miners
Before diving into specifics, it’s essential to understand how noise is measured in mining hardware. Sound levels are quantified in decibels (dB), with typical ASIC miners ranging between 75 dB and 85 dB at full load. For context:
- 60 dB: Normal conversation
- 70 dB: Vacuum cleaner
- 85 dB: Heavy traffic or a blender
- 90+ dB: Prolonged exposure risks hearing damage
Since mining rigs run 24/7, even moderate noise can become disruptive over time. The A1566-185T, like most high-performance ASICs, relies on powerful fans for cooling, which contribute heavily to its acoustic footprint.
Avalon A1566-185T Noise Performance: Key Measurements
1. Baseline Noise Output
The A1566-185T operates at approximately 75–80 dB under normal conditions. This measurement is taken at a distance of 1 meter from the miner, simulating a typical mining farm environment.
Compared to competitors:
- Bitmain Antminer S19 Pro (110 TH/s): ~75 dB
- Whatsminer M50 (126 TH/s): ~82 dB
- Avalon A1246 (90 TH/s): ~78 dB
While not the quietest miner available, the A1566-185T remains within industry standards for high-efficiency SHA-256 miners.
2. Fan Speed and Noise Correlation
The miner uses dual 12050 fans (120mm diameter, 50mm thickness), which adjust speed based on temperature:
- Low load (cool environment): Fans run at 40-50%, reducing noise to ~70 dB.
- Full load (hot environment): Fans ramp up to 80-100%, pushing noise toward 80+ dB.
Key takeaway: Proper ventilation and ambient temperature control can help lower fan speeds, reducing noise without throttling performance.
3. Frequency and Tone of Noise
Beyond decibel levels, the type of noise matters. High-pitched whines are more irritating than low-frequency hums. The A1566-185T produces a mid-range airflow roar, which is easier to dampen than high-frequency fan noise found in some competing models.
Factors Affecting Noise Levels
Several variables influence how loud the A1566-185T will be in practice:
1. Operating Environment
- Hot climates force fans to work harder, increasing noise.
- Enclosed spaces cause sound reverberation, amplifying perceived loudness.
- Ventilation efficiency impacts fan workload—better airflow means quieter operation.
2. Miner Placement and Stacking
- Single-unit setups (e.g., home mining) allow for better sound dispersion.
- Dense mining farms (racks of multiple miners) create compounded noise, often exceeding 85 dB in confined spaces.
3. Firmware and Power Settings
Some firmware optimizations allow for fan curve adjustments, trading slight temperature increases for noise reduction. However, this should be done cautiously to avoid overheating.
Noise Reduction Strategies for the A1566-185T
1. Soundproofing Enclosures
- DIY Solutions: Foam panels, acoustic blankets, or plywood boxes lined with insulation.
- Commercial Options: Pre-built mining containers with noise-dampening materials.
Effectiveness: Can reduce noise by 10–15 dB, making the miner tolerable for residential setups.
2. Improved Ventilation & Cooling
- External ducting redirects hot air away, allowing fans to run slower.
- Liquid immersion cooling (advanced setup) eliminates fan noise entirely but requires significant investment.
3. Strategic Placement
- Basements or garages naturally contain noise better than open rooms.
- Vibration pads under the miner reduce structural noise transmission.
4. Fan Replacement (Advanced)
Some miners experiment with aftermarket fans, though this may void warranties. The A1566-185T’s stock fans are optimized for durability, so replacements should match OEM specs.
How Does Noise Impact Profitability?
While noise itself doesn’t affect hash rate, regulatory and logistical challenges can arise:
- Residential bans: Some areas prohibit loud mining operations.
- Worker health: Prolonged exposure to >85 dB requires hearing protection in industrial settings.
- Hosting limitations: Data centers may impose maximum dB limits per rack.
For large farms, investing in sound mitigation early prevents costly relocations later.
Conclusion: Is the A1566-185T Suitable for Noise-Sensitive Setups?
The Avalon Miner A1566-185T is a powerful and efficient Bitcoin miner, but its 75–80 dB noise output means it’s not ideal for bedroom mining without modifications. However, with proper ventilation, soundproofing, or strategic placement, it can operate effectively in:
- Garages or sheds
- Dedicated mining warehouses
- Soundproofed home setups
For enterprise miners, the noise is manageable within large facilities, especially when compared to less efficient models.
Final Recommendation:
- Home miners: Use enclosures or remote placement.
- Farm operators: Optimize airflow to keep fan speeds (and noise) down.
- Hosting providers: Ensure compliance with local noise regulations.
By understanding and addressing the A1566-185T’s acoustic performance, miners can maximize uptime while minimizing disruptions—striking the perfect balance between power and practicality.
