The FLUMINER T3 is unusual in the Bitcoin ASIC market because it targets the space between a small hobby miner and a conventional high-noise data-center machine. Its headline configuration combines 115 TH/s with 1,700 W, while LeedMiner also lists a 110 TH/s version at 1,626 W. That puts both catalog variants near 14.78 J/TH and makes the T3 worth examining for a home office, workshop or small professional deployment where electrical capacity, acoustics and heat matter as much as raw hashrate.
This detailed review separates manufacturer specifications from operating assumptions. Hashrate, power, pool revenue, network difficulty and local electricity prices all change the outcome. Treat the figures below as planning inputs, then verify the delivered unit, firmware mode and wall power before committing capital.
FLUMINER T3 specifications at a glance
FLUMINER's current official T3 manual describes the 115 TH/s version as a SHA-256 miner rated at 115 TH/s ±5% and 1,700 W ±10%. It specifies air cooling, approximately 50–60 dB under stated conditions, RJ45 Ethernet, Wi-Fi 5.0 and a compact 3U-style enclosure. Read the official FLUMINER T3 manual before installation because tolerances, included accessories and setup steps matter.
The LeedMiner product catalog currently records:
- 115 TH/s version: 1,700 W, 14.78 J/TH, air cooling and 110–240 V planning range;
- 110 TH/s version: 1,626 W, 14.78 J/TH, air cooling and the same catalog voltage range;
- Ethernet connectivity, approximately 12.8 kg and a compact chassis;
- SHA-256 support for Bitcoin and other compatible networks.
Catalog values help compare products, but the manufacturer's nameplate and manual govern the delivered machine. Confirm input voltage, plug, power cable and regional certification with the quotation.
Efficiency: the strongest part of the T3 proposition
At 14.78 J/TH, the 115 TH/s and 110 TH/s entries are materially more efficient than many older home-mining experiments. Efficiency tells you how much miner power is required for each terahash; lower is better. It does not include router, ventilation, air conditioning or other facility loads.
The simple daily energy calculation for the 115 TH/s model is:
1.70 kW × 24 hours = 40.8 kWh per day
At an all-in rate of $0.10/kWh, miner-only electricity is about $4.08 per day or $122.40 per 30-day month. At $0.15/kWh, it becomes $6.12 per day or $183.60 per 30-day month. The 110 TH/s, 1.626 kW version uses about 39.0 kWh per day before ventilation or cooling overhead.
These are energy costs, not profit estimates. Bitcoin-denominated revenue changes with network difficulty, block subsidy, transaction fees, pool terms and accepted hashrate. Use the LeedMiner profit calculator with current data, then replace the default electricity rate with the delivered rate from your bill.
Noise and heat in a real room
FLUMINER positions the T3 as a quieter miner. The official manual reports approximately 50–60 dB under its test conditions, while the LeedMiner catalog uses a 50 dB planning value. Those figures should not be converted into a universal room result. Noise changes with fan speed, ambient temperature, distance, reflections, dust loading and whether the miner is inside a cabinet.
A 1.7 kW device also releases roughly the same power as heat into the room. Even when the fan tone is tolerable, the heat may not be. Plan a direct path for warm exhaust, keep intake and exhaust separated, and do not recirculate hot air. Measure room temperature and miner inlet temperature during the hottest expected weather rather than relying on a short cool-day test.
The T3 can be more comfortable than a conventional industrial ASIC, but it is not silent and it is not a substitute for ventilation engineering.
Electrical planning deserves extra care
The wide voltage range is attractive, but voltage compatibility alone does not mean every outlet is suitable. A 1,700 W continuous load draws roughly 14.2 A at 120 V before power tolerance and losses. That is close to the practical continuous-load limit of many common circuits. Other devices on the same branch, an undersized extension cord or a poor connector can create heat and nuisance trips.
Have the intended circuit, breaker, receptacle, grounding and cable checked for a continuous load under local rules. A correctly engineered higher-voltage circuit generally reduces current for the same power, but the exact installation must match the supplied power input and local electrical code. Do not improvise adapters or defeat protective devices.
Setup and first-week verification
A disciplined commissioning process is more useful than a one-minute power-on test:
- Inspect the chassis, fan guards, connectors and shipping condition.
- Confirm the exact variant and serial number against the invoice.
- Place the miner with unobstructed intake and exhaust clearance.
- Connect Ethernet first when possible; use only the official setup method for Wi-Fi.
- Change default credentials and record the local IP address.
- Configure at least two pool endpoints and verify the worker name.
- Let the miner stabilize, then compare dashboard hashrate with pool-side accepted hashrate.
- Measure wall power, inlet temperature, exhaust temperature and room noise over several hours.
Bitcoin's proof-of-work mechanism is documented in the Bitcoin Developer Guide. The protocol does not guarantee a fixed return to an individual machine, so pool-side history and current network data remain essential.

Who should consider the T3?
The T3 can fit a buyer who wants meaningful SHA-256 hashrate in a smaller, quieter format and already has a suitable circuit plus a plan for continuous heat removal. It may also suit a small commercial operator testing a room before expanding.
It is a weak fit for a renter without permission to add electrical or ventilation capacity, a bedroom that must remain quiet and cool, or an operator whose electricity price makes the stress-case margin negative. A lower-noise label does not remove the need for heat, electrical and network planning.
Verdict
FLUMINER T3's strongest combination is compact form, approximately 14.78 J/TH catalog efficiency and lower acoustic ambition than a typical industrial air-cooled miner. The trade-offs are a continuous 1.6–1.7 kW load, substantial room heat and economics that still depend on current Bitcoin network conditions.
Compare the two variants in the ASIC comparison tool, model electricity and difficulty conservatively, and contact LeedMiner with your country, voltage, electricity rate, room dimensions and preferred batch. Ask for a current quotation and an installation check rather than relying on a historical profitability screenshot.
