81TH 3420W A1246 Canaan Avalon Bitcoin Miner 42W / TH LTC Miner Machine

Description:

The device comes with four fans. These fans help in the dissipation of heat from the machine. The machine produces a lot of heat due to its high hash rate and its high power consumption. Still, the four fans' presence helps to keep the machine at a temperature where it is optimal and efficient by dissipating the heat produced from the machine.

To improve the heat dissipation, the A1246 device is highly equipped with a high temperature resistant 12038 cooler master fans. The front has dual fans, and these fans are for air inlet. They have seven blades each, which further increases the air contact area pressure, deepening airflow penetration to the enclosure while the interior dust is blowing away. This particular design helps prevent dust accumulation on the dashboard, which can cause a short circuit due to static electricity.
