Replacing tutorial for Whatsminer DZ06038B12XG PSU fan

With its high airflow and premium metal bearing, DZ06038B12XG 12V 2.16A PSU cooling fan becomes the best replacement of Whatsminer faulty PSU fan. It's suitable for various models such as P21, P221B, P221C, P222B, P222C etc., helping the miner's power supply dissipate heat efficiently to maintain its stable operation and extend its lifespan.

The PSU fan has four different versions with different connectors and cable sequence:

Version 1, 2, 3 have different connectors but the same cable sequence: black-negative, yellow-signal, blue-control, red-positive;

Version 4 has the same connector as version 1 but a different cable order: black-negative, red-positive, yellow-signal, blue-control.

Typically, version 1 is suitable to the older power supplies like P21, while version 4 is used to the newer ones like P221 and P222.

As miners operate under high loads for a long time, the power supply fan needs to work continuously to cool the PSU, making it one of the most vulnerable components. If the miner appears abnormal noise or temperature rise, there may be some malfunctions of the PSU fan.
