In April 2020, MicroBT, one of the leading crypto mining hardware companies, released the MicroBT Whatsminer M30s, the first in its M30 series. It was clear MicroBT meant business this time, as shown in the improvements from the older M20s version and the wide acclaim that followed the release. MicroBT has quickly built a reputation for being one of the leading equipment providers in the space, with a commitment to transparency and reliability.

Of appearance, the size is 150 x 255 x 390mm, and the weight is 10.5kg. The difference between the M30S and M20S is that the power supply is replaced with a flat style, which reduces the machine's height by 15mm, and at 0.9kg, the weight of the whole machine is lighter than the M20S-68T. The device uses one input, one output system with two dedicated fans for cooling. The air inlet fan comes with a protective metal cover.

At optimal mining conditions, this miner's temperature is around -5 — 35 °C, which can be expected due to the cooling fans' efficiency. Also, due to the fans, the noise level is reduced. Average miners have a noise level of about 75 dB and above, but this device has a noise level of just 72dB.
