Miners are ranked by Noise Level (lowest first). Profitability is calculated server-side using live BTC price and network difficulty, with a default electricity rate of $0.0735/kWh (Quebec average). Daily revenue uses the standard formula: (hashrate x 10^12 x 86,400 x block_reward) / (difficulty x 2^32). You can adjust the electricity rate above to recalculate profitability for your location.

Frequently Asked Questions
How loud is a typical Bitcoin miner?
Full-size ASICs like the Antminer S19 run at 75+ dB — comparable to a vacuum cleaner. Open-source miners like Bitaxe run at 30-45 dB, similar to a whisper or quiet fan.
Can I make a loud miner quieter?
Yes — options include fan replacement with Noctua fans, immersion cooling, custom shrouds with sound dampening, or D-Central Space Heater enclosures designed for noise reduction.
Is there a silent Bitcoin miner?
No miner with fans is truly silent, but the Bitaxe with a passive heatsink can run nearly silent (under 30 dB). Immersion-cooled setups are also extremely quiet.
Can I mine Bitcoin in my bedroom?
With a Bitaxe or NerdAxe, absolutely. These devices produce less noise than a desktop computer fan. Full-size ASICs should be in a garage, basement, or utility room.
What dB level is acceptable for home mining?
For living spaces, aim for under 45 dB. For a separate room, up to 65 dB is tolerable. Above 75 dB requires hearing protection for extended exposure and dedicated isolation.
How many miners qualify for this list, and which ranks first?
4 miners currently meet this page's criteria. The Canaan Avalon Nano 3S official owner reference ranks first by noise level. Rankings recompute automatically as our ASIC Miner Database is updated, so this list stays current.
How much does efficiency vary across these miners?
Efficiency on this list ranges from 21.3 J/TH to 96.0 J/TH. Lower J/TH means less electricity per unit of hashrate — at scale, that gap compounds into a meaningful difference in your monthly power bill.

This calculator converts miner wattage into daily, monthly, and yearly electricity costs.
Energy use is calculated as watts / 1000 x hours per day.
Cost is calculated from the entered kWh rate or the selected provincial rate.
Appliance comparisons use typical wattage values and are intended as a practical reference point.
Data sources: user inputs, network or market data available on the page, manufacturer specifications, and the displayed assumptions. Verify results before making financial or electrical decisions.
Rankings update automatically with live market data. Profitability estimates use current BTC price and network difficulty and do not account for pool fees, hardware degradation, or price changes. Not financial advice. Electricity rate default is Quebec residential ($0.0735/kWh).
