Whatsminer M10 Bitcoin Miner Report

Introduction
MicroBT, also known as Shenzhen Bit Microelectronics Technology Co., Ltd., has come out with their latest WhatsMiner: the M10. The M10 is a bitcoin miner which runs on the new 16nm ASIC (QA1800) chip. Like its predecessors, it includes a controller unit and power supply.

What makes the M10 stand out is its improved performance and efficiency. The M10 provides an impressive hash rate of 33.0 Th/s using the SHA-256 algorithm, consuming only 2150W.

An important aspect to note is that the input voltage must be 176-246V. This means the regular AC voltage of 120V in North America is not sufficient.

Disassembly and Part Identification
The following section shows the components of the miner through disassembly. Below, you can see the controller.

Each hash board is connected to the power supply using a connector board, as shown below.

There are two heat sinks that are screwed onto the chips. These two can be removed. The larger heatsink at the back is melded to the board and cannot be removed.

A lot of precautions and careful planning were put into the design of this miner. As shown in the picture below, the springs used to fasten the heat sink to the chips includes screws. This allows the product to hold up better to moderate vibration while also spreading out the tension.

Upon removing the heatsinks, we can see that thermal paste was used on the underside of the removable heat sinks and covers all chips. The thermal paste acts as another layer to secure the heatsink to the chip board with minimal heat build-up.

Note that towards the bottom-half of the image below, the chips are spaced quite close together with smaller heat sinks between the chips. This is because that portion of the board is closest to the fan and receives the most cooling. As you look towards the top of the photo, the chips are spaced further apart with larger heat sinks to compensate for the lower airflow, ensuring that the unit does not overheat during operation.
