How to replace the YD12038B2G cooling fan for Avalon 1246 miner?

The YD12038B2G 12mm 4 pin square chassis cooling fan is a customized cooling solution specifically for Canaan Avalon series miners (such as A1246, A1166, A1146, A1126, A1066pro, etc.). With a maximum speed of up to 6000rpm, it can quickly and effectively dissipate the heat generated by the miner during hashing operations, improving mining efficiency. It features a noise-reduction low-power design, maintaining a low noise level even at high speeds, providing miners with a quieter mining environment.

If the cooling fan malfunctions, the large amount of heat generated by the miner's operation cannot be discharged in time, leading to a continuous increase in internal temperature. This not only reduces mining efficiency, but long-term high temperatures can accelerate component aging, potentially causing hardware damage, even threatening the stability and lifespan of the machine. Therefore, it is crucial to promptly detect and replace the faulty one, ensuring the miner continues to operate efficiently.

The YD12038B2G 12V 4.5A cooling fan is the best replacement for faulty chassis fans in the Avalonminer series.

The specific replacement steps are as follows:

1. First, we need to check the miner's background operation log to find the serial number of the faulty cooling fan.

2. Next, shut down the miner, disconnect the power cord, unplug the fan connector, and remove the protective cover plate on the top of the control board.

3. Locate the position of the faulty fan according to the corresponding serial number of the control board fan interface, remove its fixing screws, and take it off along with the protective net.

4. Check the label of the new YD12038B2G cooling fan to confirm that the model matches the miner, observe whether there are obvious depressions on its overall appearance, and inspect the wire for any breaks or damage.

5. Use screws to pass through the screw holes of the protective net and the cooling fan sequentially for easy fixing later.

6. Align the fan with the holes, then tighten its screws.

7. Install the protective cover plate removed earlier, connect the fan connector to the corresponding interface, ensuring a secure connection.

8. Power on the miner to observe the operation of the new fan.

Cooling fans play a crucial role in the cooling system of air-cooled miners, not only improving mining performance but also extending the machine's lifespan. The YD12038B2G chassis fan is the most economical and efficient choice for the Avalonminer series, providing miners with a better mining experience.
