2. Installing the fan

Put the new fans into the correct position, then install. You can take the above tutorial for reference. Remember to confirm the airflow direction when installing. TIP: the air flow arrow should point to BOX inside.

Installing the fan in the wrong direction may lead to the miner shutting down at high temperatures, and even causing irreversible damage!

2.1 Please refer to Figure 7 and observe the symbol on the fan. When installing the fan on the metal plate, make sure that the "AIR FLOW" arrow points towards the inside of the miner, as shown in Figure 7. Install the eight screws of the two fans in their respective positions, as shown in Figure 8.
