Antminer L3+ is an addition to Bitmain's Antminer Application Specific Integrated Circuit flagship brand. Bitmain produces it, a giant in the mining industry. Launched in 2013, the Antminer brand has been one of the leading brands in technical specifications and excellence in produced miners quality. The Antminer has over 75% share in the mining industry worldwide. 

Due to the popularity of Litecoin, there was a demand for mining hardware that can mine the coins. Bitmain produced and started shipping the Antminer L3 series from the end of 2016. The L3 series consists of L3+ (504Mh), L3++(580Mh), L3++(596) and L3+(600Mh). All L3 models come with an impressive BM1485 Litecoin ASIC chip. 

The BM1485 is the first Litecoin Application Specific Integrated Circuit(ASIC) useful chip for mining Litecoin. Each Litecoin miner has 288 of such chips in its framework. Litecoin miners are also known as Scrypt miners. 

The L3 miners can mine any coin on the Scrypt algorithm.

Features of Antminer L3+

Antminer L3+ (600Mh) has a dual-fan arrangement at the rear and front sides with a suitable aluminum shell case. The arrangement is consistent with the previous model's design. It weighs about 4.4kg with size dimensions of 188 x 130 x 352mm, making it smaller than most miners with an added advantage of convenient handling and stacking.

The fan arrangement is the IP button, network cable socket, and reset button on the front of the miner. The top's data cables are buckled to prevent wear and tear and for steady data transmission. The Antminer L3+ comes with Bitmain's 10nm ASIC chip, which, coupled with the hash rate and low power consumption, makes the miner powerful. The miner also comes with an APW3-12-1600-B2 power supply unit, which converts at the rate of 93%. 

Algorithm

Every miner's algorithm is essential as it decides the top coin and scale of profitability for the device. Since the L3 miners are specifically for mining Litecoin, they work with the Scrypt algorithm. Scrypt is an encryption method that requires lots of time for selection and uses significant memory volumes. It is used in many altcoins as Proof of Work (PoW). Made for Tenebrix and released in 2011, it serves as the basis for Litecoin and Dogecoin, based on the Scrypt algorithm. 

The Scrypt algorithm is for crypto-coin mining, which makes it more complicated for specialized ASIC miners. Coins mined from Scrypt are different from Bitcoin as Bitcoin uses the SHA-256 algorithm. 

Cooling Method

The Antminer L3+ comes with a high-quality aluminum case that protects it from dust and heat with two fans at the rear and front for cooling. This design is just like the previous models of the L3 series. To achieve effective cooling, Antminer L3+ uses a combination of conduction and convection to cool the device. This cooling process ensures that the miner does not overheat even at maximum capacity, which is an added advantage over terahash miners. 

Inside the miner, it has high-grade aluminum heat sinks on every chip, which raises the heat-absorption capacity. The two fans at the end of the tubes are arranged to dispose of hot air, thereby cooling it immediately. This heat absorption process shows the L3+ can work at maximum power while keeping itself cool. 

Power Consumption

Notable for its low power consumption, the L3+ is ideal for people who want to mine at home. The L3+ has a power consumption of about 850W, and for users with free electricity, it is an added advantage as it reduces electricity costs. Calculating the electricity cost at 0.1 per KwH, users can enjoy some profit after a day's work.

Fan and Air Circulation

The Antminer L3+ has a 12cm fan of 12V 2.3A at the front side for air intake. The miner also has another 12cm fan at the end for taking out the air and heat. These two fans do an excellent job maintaining a stable mining condition by cooling the device and preventing overheating. During normal mining operations, the fan speed is at 4300 rotations per minute, which is quite useful.

Noise Level

Most miners' noise level is about 60db to 70db, but the Antminer L3+ has a noise level of 75db. The four dedicated fans are working to maintain stable mining conditions and prevent overheating cause the noise level. The standard fan setting adjusts automatically based on the ambient temperature. The Antminer L3+ is suitable for mining at home as the noise level is optimized but is best kept at mining farms.

Profitability

The profitability of the Antminer L3+ depends on the electricity rates of the area and the market conditions. Profitability may vary daily, depending on electricity costs; the device will profit when the market favors the top coin.
