Quiet ASIC miner for Dogecoin and Litecoin: Fluminer L1 and alternatives

The Fluminer L1 is a quiet ASIC miner for the Scrypt algorithm: it mines Litecoin and Dogecoin at the same time, delivers 5.3 GH/s at a power draw of 1,200 W, and the manufacturer states a noise level of around 40 dB. This means it can run in a study, office or garage where a typical 75 dB industrial miner would be unbearable. Below you will find its specifications, today's earnings and a comparison with other quiet miners for LTC and DOGE.

Summary

• Fluminer L1: 5.3 GH/s, 1,200 W, efficiency 0.226 J/MH, around 40 dB, 12.8 kg.
• It mines Litecoin and Dogecoin simultaneously (merged mining) – the earnings from both coins add up.
• Gross earnings as of 18 Oct 2026 are around CZK 66 a day, with consumption of 28.8 kWh a day.
• It pays off mainly with cheap electricity from your own solar panels or where you use the miner's heat for heating.

Why the Fluminer L1 is quiet

Typical Scrypt miners such as the Antminer L9 draw 3–3.5 kW and have fans running at around 75 dB. That is the noise of a vacuum cleaner, 24 hours a day. The Fluminer L1 draws roughly a third of that, so slower cooling is enough.

The manufacturer states a noise level of around 40 dB, the level of a quiet fridge. In practice it depends on the room temperature: in a warm space, the fans speed up. Also bear in mind that 1,200 W of heat will noticeably warm a room – an advantage in winter, but in summer you will need to ventilate.

How much the Fluminer L1 earns

Scrypt miners mine Litecoin and, “for free” on top, Dogecoin, because the pool searches for both blocks with the same work. Today 1 GH/s earns 1,86 Kč in Litecoin and 10,60 Kč in Dogecoin per day, roughly CZK 12.46 in total.

At today's difficulty and exchange rate, the Fluminer L1 with 5.3 GH/s therefore mines approximately CZK 66 a day gross (as of 18 Oct 2026). Over the same period it uses 28.8 kWh. Mining therefore covers its costs as long as you pay less than about CZK 2.29/kWh for electricity.

If you pay more at home (including distribution and fees), pool mining on its own loses money. It makes sense with surplus solar power, or when the miner replaces a direct heater and you would be paying for the heat anyway. Earnings change with coin prices and network difficulty – you will find current figures for all machines in our ASIC miner profitability overview.

Quiet LTC and DOGE miners compared

The Fluminer L1 is not the only quiet Scrypt miner. For comparison, we calculated today's earnings and the electricity price at which mining just pays for itself (break-even). The figures are as of 18 Oct 2026, at earnings of CZK 12.46 per 1 GH/s a day.

The table gives a simple rule: the lower the J/MH, the more expensive the electricity a machine can “bear”. Smaller machines (L2, D1 Mini, DG Home 1) are suitable for a flat where you don't want more than 250–650 W of heat. The L1 and L1 Pro are better suited to a garage, workshop or plant room.

Who a quiet Scrypt miner is for

• Solar panel owners – it turns surplus power you would otherwise sell cheaply to the grid into LTC and DOGE.
• Those who want to heat with mining – the miner turns practically all its electricity into heat, much like a direct heater.
• An office or study – noise up to 50 dB is bearable even in a room where people work.

If you have expensive electricity and won't use the heat, it is better to place a larger, more efficient machine in hosting, where the cheapest location currently costs 1,13 Kč per kWh. Our soundproof box can also quieten a noisier miner at home.
