What is the IceRiver KS3M 120mm cooling fan and how can it be replaced?

DF1203812B2UN 120mm fan is a cooling fan for Iceriver ks3m KASPA miner. Its size is 120*120*38mm, consumes 32.4W power, and operates at a speed of 6000PRM. It features pure copper wire cores and high-precision double-ball bearings. It is equipped with a 4-wire PWM temperature control speed adjustment function, ensuring efficient heat dissipation for miners and extending their lifespan.

If the miner's cooling fan experiences issues such as reduced speed, failure to operate, or an abnormal increase in noise, it may be damaged. In such cases, it's necessary to promptly replace the cooling fan to avoid excessive internal temperatures of the miner, this can cause the hash board to stop functioning or even cause more serious failures such as burning.

When the ks3m miner has these failures caused by faulty fans, please refer to the following steps to replace the damaged cooling fan:

1. Locate the faulty fan's position based on the Iceriver KS3M miner's operational logs and the interface number of the control board fan.

2. Disconnect the KS3M miner's power supply, and remove the protective cover plate above the control board.

3. Unscrew the fixing screws of the faulty fan's protective grille, unplug the connection cable between the fan and the control board, and take out the faulty cooling fan.

4. Install the new fan in the original position, securing the fan and its protective grille with screws (ensure that the new fan's size and interface match those of the original cooling fan before installation).

5. Insert the fan plug into the corresponding fan interface on the control board, and reinstall the Iceriver KS3M miner's protective cover plate.

6. Reconnect the KS3M miner's power supply, then restart the miner. Check the operation of the new fan and whether the miner's temperature has returned to normal.

The operational status of the miner's cooling fan is crucial for its overall performance. If any faults are detected, be sure to replace cooling fan promptly to ensure the miner's cooling effectiveness and stable operation.
