How to replace the damaged W12E12BS11B5-07 cooling fan for Antminer KS5 miner?

The W12E12BS11B5-07 12V 1.65A 6000RPM 120mm cooling fan can be used to replace faulty chassis cooler fans of Antminer KS5 KS5pro, helping them to efficiently dissipate heat. It adopts high-quality double ball bearings, comes with a 4pin  plug, supports the PWM temperature control function, and has a maximum air volume of up to 197CFM. Additionally, it is also suitable for other Antminer miners that use 120mm 4-pin interface cooling fans, such as S17, S17 Pro, S17+, T17, T17E, S19, S19 Pro, S19j Pro, D7, L7, KA3, S21, T21, etc.

The cooling fan is the most critical component in the air-cooled miner's cooling system. Once it fails, it will directly affect the overall cooling efficiency, leading to a failure to timely dissipate the heat generated by the running hash boards, causing the internal temperature to rise. This will not only affect mining efficiency but can also lead to overheating damage to other electronic components. At this point, promptly replacing can help the miner resume normal operation, ensuring mining revenue.

The specific replacement method for the W12E12BS11B5-07 120mm cooling fan is as follows (taking the KS5 miner as an example):

1. Login to the miner's background management interface and determine the number of the faulty cooling fan based on kernel logs.

2. Shut down the miner, disconnect the power cable from the power socket. Wait for a few minutes to allow the machine cool, avoiding burns during operation.

3. Remove the protective cover plate on the top of the miner, then unplug the fan connector, ensuring that the control board and its fan interface are clearly visible.

4. Identify the location of the faulty fan based on the control board fan interface number, remove its fixing screws, and take it off together with the protective net.

5. Inspect the new W12E12BS11B5-07 cooler fan for any visible damage to its overall appearance, then align it with the screw holes, secure it and its protective net with screws.

6. Connect the fan connector, and secure the protective cover plate, ensuring a stable connection.

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

With its excellent performance, the W12E12BS11B5-07 cooling fan safeguards the operation of the miner! Promptly replacing faulty chassis fans can not only restore efficient cooling but also effectively extend the lifespan of the machine.
